    All our baselayers act like a second skin. Extremly slim fit cut with extended back side for lower back protection. Whatever Isadore jersey size you are used to wear, this baselayer will certainly fit you in the same size. However if you prefer more casual fit, we advice you to choose one size bigger than the Isadore jersey you are used to.

    • A second skin

      Stefano Nucera, Germany, 21.12.2017

      I'm using it in winter (under a jacket) and I used it in summer (below my Echelon Jersey) and it keeps perfectly the body temperature. And the cut is really comfy. Only your skin has the same body fit :)

    • Can't Fault It

      Gary O'Sullivan, Ireland, 22.12.2016

      A superb piece of kit, standing up well to lots of use. I love the transferred on washing instructions. I find the fit great with arm length, torso length and head size all being just right. Doesn't ride up, doesn't develop smells and looks good

    • Comfortable and breathable (100% Merino SS Baselayer Black)

      Nathan Thomas, United Kingdom, 19.5.2020

      Had my 100% Merino SS baselayer for a couple of years now, and it still feels very soft and comfortable against the skin. Mine did shrink a little after a few washes even after following the care instructions, so in future I might be inclined to size up.

    • Top baselayer (100% Merino SS Baselayer Grey)

      Miguel van den Wildenberg, Germany, 18.10.2019

      My first Merino wool baselayer; I don't want anything else:) Following other reviews, I have ordered a size larger than normal. Size L is just perfect: 1.86m/72kg.

    • COMFORT & FUNCTION (100% Merino SL Baselayer Grey)

      beno trček, Slovenia, 13.5.2019

      Excellent,for the time being I don't have any comments!Base layer serves his purpose

    • Excellent (100% Merino SS Baselayer Black)

      Pascal Gerritsen, Netherlands, 4.9.2018

      I wear size L but next time i will try XL. I'm 1.93 and 78 kilo. Jersey is L but bas will be XL. Top quality, always wear Rapha, but this is much thicker and it fits better.

    • Simply a charme (100% Merino SL Baselayer Golden Oak)

      Markus, 2.9.2018

      Very lovelly on the skin and works to keep warm without creating heat on a harder training session.

    • Light warm and breathable (100% Merino SS Baselayer Grey)

      Christophe Verlinde, Belgium, 30.4.2018

      Light enough to wear in warm weather, but warm enough also to be worn in rather chilly mornings. Very breathable and odorless if you do multiple day rides. I followed the advice to take a size bigger. Took size L, I'm 186cm and weight 73 kg

    • Spot on (100% Merino SS Baselayer Black)

      Mark Botham, United Kingdom, 17.1.2018

      Had the l/s for a few years and it's been great. Don't know why but tried 2 other brands before going back to Isadore. It was the only one that fitted well, didn't itch and keeps me warm. You pay for quality.

      Sascha Hartmann, Germany, 22.8.2017

      perfekte Passform - tight, long & stylisch ...

    • perfekt (100% Merino SS Baselayer Grey)

      robert kalasek, Austria, 21.8.2017

      hatte urspruenglich grau bestellt - "leider" gab es nur noch golden oak. seit dem ersten mal ausfahren bin ich ziemlich gluecklich mit golden oak. werde noch ein grau bestellen sobald es wieder verfuegbar ist. komfort, optik, gefuehl - alles passt. bezgl. groesse: wuerde im zweifel zur groesseren variante raten. mein SS in L ist sehr sehr knapp. XL passt ohne, dass irgendwo ewtas flattert - laut tabelle wuerde ich mit 190cm und 81kg ziemlich dazischen liegen.

    • Perfect baselayer (100% Merino SS Baselayer Atlantic Blue)

      Pierre Geronimo Corvaia, Austria, 1.2.2017

      Short sleeve baselayer is thinner then the longsleeve baselayer. I am 175, 84 kg and wear an L. The baselayer is also longer then the longsleeve baselayer and covers more of your thighs. The quality is awesome after several times of washing it still looks as new - highly recommendable I just ordered a new one in grey

    • Essential item in my wardrobe (100% Merino SL Baselayer Atlantic Blue)

      Pierre Geronimo Corvaia, Austria, 1.2.2017

      Sleeveless baselayer is thinner then the longsleeve baselayer. I am 175, 84 kg and wear an L. The baselayer is also longer then the longsleeve baselayer and covers more of your thighs. The quality is awesome after several times of washing it still looks as new - highly recommendable I just ordered a new one in grey

    • Excellent baselayer but watch the sizing... (100% Merino SS Baselayer Grey)

      Martin Page, United Kingdom, 9.11.2016

      Really nice material, quite thin but it seems to suit a wide range of temparatures. I like the design at the neck. I wear size medium in Isadore jerseys and shorts, and bought this baselayer in medium. It was a fairly snug fit, but after the first wash it shrunk slightly, and is now a bit on the tight side, and quite short at the waist. (I followed the washing instructions!) Having been so impressed with the quality of other Isadore garments I was a bit disappointed, but I will buy more baselayers in size large to allow for shrinkage...

    • Very good quality, very tight fit (100% Merino SS Baselayer Grey)

      Oliver, 22.8.2016

      Well, if you know Merino, you know what it's worth. This piece is no exception. What you need to know, is that sizing is really tight. I usually wear L in all my shirts and trikots, which gives me a good fit. This baselayer is tighter than any other piece of wardrobe so far. I took XL, if I were to buy another one.

    • Athletic slim fit (100% Merino SS Baselayer Grey)

      Dusan Samudovsky, Slovakia, 1.8.2016

      Unboxing Isadore is like opening jewelry box. When trying on the tight fit is paramount for baselayer. This is tight at XXL for 193cm and 78kg with 96cm chest exhaled. XL is also good but I was afraid of possible shrinking after multiple washing and this is baselayer which is washed often, plus the extra cm to cover the back. I have the LONG SLEEVE JERSEY INDIGO BLUE in L (though XL would be very good fit as well) for reference and XL for bibs. It is a bit itchy for the first moment as almost all merinos but after a while I forget about it.

    • Base layer not basic (100% Merino SS Baselayer Grey)

      Rhett Butler, France, 20.12.2015

      If you are going to wear a base-layer it wants to be fabulous. These are, riding or socializing these are great, tight fitting so if you work out and want people to notice wear the base as a t-shirt and with the shaped collar it looks the dogs wotsits, on the road all day comfortable and keeps me warm and feeling dry. Top product !!!!

    • classsy colour and great wool feeling (100% Merino SL Baselayer Grey)

      cem atiyas, Turkey, 6.11.2015

      great colours and material. very fit cut but still god feeling o n he skin.

    • Perfect Styling (100% Merino SL Baselayer Grey)

      Royce Walston, United States, 23.10.2015

      Base layers have always been a struggle for me. I could never find one that offered the comfort and temperature range suitable. This has all changed with Isadore. This base layer is perfect, with genuine comfort in a wide range of temperatures. Treat yourself to exceptional quality and comfort.

    • Perfect comfort (100% Merino SL Baselayer Grey)

      Stephen Ridett, Denmark, 1.9.2015

      Used my new sleeveless base layer today - together with my new Signature jersey - on a 2 hour spin. Very comfortable, nice fit and no annoying tightening under armpits when on the drops. Can recommend jersey and base layer.

    • Incredible bit of kit (100% Merino SL Baselayer Grey)

      Ed Newey, Switzerland, 27.7.2015

      I have now ridden with this in cooler conditions and in baking hot sun. it is amazing how well it performs in both environments. in cooler conditions the wool blend is cosy and just takes the edge off. This weekend on a hot sun baked, brutal mountain climb it wicked the sweat away and kept me extremely comfortable. At the top the temperature fell drastically. I zipped up, wool arm warmers on to begin the descent and it was back to cosy time again. Ive bought 2 shortsleeve layers (will get 1 more when restocked) and will order a long sleeve for the winter. One guy on this ride had the long sleeve on and even on the climb going into cooler air he found it worked beautifully. and on the train home we didnt clear the seats around us... Another fabulous product from Isadore

    • Stylish second skin (100% Merino SS Baselayer Grey)

      Philippe Lemmens, Belgium, 15.7.2015

      I have the short sleeve merino in black. This is like a second skin, so comfortable you don't feel you have this base-layer on. It evacuates sweat, so no uncomfortable feeling from this shirt when riding hard. It adds warmth without one feeling it, so good base-layer for intermediate temperatures (10-20° C.). Very stylish!

    • A really good buy. (100% Merino SS Baselayer Grey)

      stephen pullman, United Kingdom, 3.6.2015

      I have two of these vests and they wash well, dry quickly, do not shrink or stretch. They are comfortable through a wide temperature range and wick moisture well, they do not become itchy when damp. The vests are also good for wearing casually after a ride. Hopefully, Isadore will add a few more colours to the range.

    • Light, Comfort & Function (100% Merino SS Baselayer Grey)

      Kevin Finch, United Kingdom, 29.4.2015

      I have a few Isadore base layers now and I don't wear any other. The merino is soft and supremely comfortable. I always wear a base, even in summer (a vest), and these are excellent for wicking moisture away. They have no odour so you don't need to worry about the cafe stop. Wash them carefully (30 degrees maximum and use delicate cleaning agents) of course, and they stay like new.

      Marcel Laros, Netherlands, 20.2.2015

      I like this Merino: no itching, but great in keeping the body dry. I also wear it casual because of the pleasant feel to the skin and perfect fit.

    • great product

      Marian Kľúčovský, Slovakia, 17.5.2017

      I used it for cycling and running during cold spring and it amazes me. It keeps me warm and dry even if sweating. It is also very comfortable and superbly cut. I am 191 cm, skinny but with wide shoulders and L size fits great.

    • Uwe (100% Merino SS Baselayer Atlantic Blue)

      Uwe Flad, Germany, 27.10.2019

      Teueres aber gutes Unterhemd aus 100% Merino. Die bestellte Grösse bei 178 cm und ca.76 kg war L. Dieses war viel zu klein und eng. Der Umtausch in XL war problemlos. In Verbindung mit dem Langarmtrikot von Isadore eine gute Lösung. Es kann bis zum waschen öfters getragen werden, Auslüften genügt, keine Geruchsentwicklung.

    • Herr (100% Merino SS Baselayer Crushed Berry)

      Felix, Germany, 15.6.2019

      Hatte das selbe Hemd schon in blaugrün. Trägt sich sehr angenehm. Körpernaher schnitt.

    • Nice cut and comfortable to wear (100% Merino SS Baselayer Grey)

      Stephan, 31.3.2019

      Very good and warm baselayer! A little bit short for me, but helps perfect during winter and spring.

    • Výborne (100% Merino SS Baselayer Crushed Berry)

      Matúš Hübler, Slovakia, 11.1.2019

      Nátelnik s výbornými termoregulačnými vlastnosťami vhodný aj na iné outdoorové aktivity, ako je cyklistika. Pri kúpe odporúčam vybrať o číslo väčší nátelník, vzhľadom na to, že je vyrobený z vlny a po vypratí má tendenciu sa zrážať. Prať len ručne!

    • Herr (100% Merino SS Baselayer Crushed Berry)

      Ulrich Ziegler, Germany, 26.10.2018

      Sehr eng anliegendes U.-Hemd, sehr knapp bei Gr. M/175cm/70kg, Evtl. minimal zu kurz geratener Rumpf, aber ich persönlich finde es super. Größe M der britischen Konkurrenz (R.) ist mir etwas zu lang, drauf sitzen mag ich nicht.. Also tendenziell eine Nummer größer, wenn man das racemäßige nicht so mag...

    • Comfy baselayer, great features (100% Merino SS Baselayer Grey)

      Tomáš, Slovakia, 17.10.2018

      Probably the best baselayer I've ever had. Nice and soft, no skin irritation :)

    • Parfait (100% Merino SL Baselayer Atlantic Blue)

      Olivier, Switzerland, 14.9.2018

      Une première couche que l'on ne sent pas et qui régule parfaitement la température de votre corps. Couleur originale. Coupe parfaite.

    • Tight and comfortable (100% Merino SS Baselayer Grey)

      Florian Possinger, Germany, 12.8.2018

      I used to buy my merion baselayer from another carrier. But now that I know the Isadore quality I'll always get them here. They fit tightly and keep me warm on cold morning rides. They don't get hot when the temperatures rise. Perfect.

      Reinhard Kinzl, Austria, 21.11.2016

      Trägt sich weich auf der Haut, perfektes Temperaturmanagement! Erst vor kurzem gekauft und schon mein Lieblingsteil! Größe S passt mir, 181cm, 76kg perfekt

    • CD (100% Merino SL Baselayer Grey)

      Claus-Dieter Kurz, Austria, 6.4.2016

      the nicest & best baselayer I've ever worn!! Only one thing for improvement: the length could be 3 -5 cm longer (my size M for 185 / 72)

    • Merino rocks! (100% Merino SS Baselayer Grey)

      Ulf, Germany, 4.4.2016

      Very nice base layer, that works excellent for longer rides in northern european weather - you'll stay warm in the morning and when the sun gets warmer the merino will cool your body - magic!

    • angenehm zu tragen (100% Merino SL Baselayer Grey)

      Arno Nym, 20.5.2015

      Man merkt gar nicht, dass man das Shirt anhat, bis man angekommen ist, Jacke auszieht und sieht, wie man geschwitzt hat. Ich fühle mich dabei nicht nass oder kalt, sondern angenehm. Das Shirt ist in kurzer Zeit wieder trocken und kann für die Heimfahrt direkt wieder genutz werden. Einzig der leichte Wollegeruch könnte als störend empfunden werden... Ich habe es auch schon mit normaler Sportwäsche bei 30° mitgewaschen - formstabil! als einziges habe ich beim Aufhängen das Rückenteil mit Klammern beschwert, dass es sich nicht einrollt. Ich werde definitiv noch weitere davon kaufen!

    • VERY GOOD PRODUCT, BAD CUT... (100% Merino SS Baselayer Crushed Berry)

      Christophe LE GONIDEC, France, 18.4.2019

      I'm very happy with Isadore signature jerseys! Size S fits perfect for me. So I decided to order 2 baselayers size S(one SL and one SS). They were suprisingly too small for me ; I had the impression to wear my child clothes! I exchange both for Medium size as Isadore Return and Exchange works very well. SL baselayer fits perfect but SS one remains too short in M and therefore very uncomfortable. Anyway, I'm happy with the first one. I wear it as often as I can. Nevertheless, I have to admit that I hesitate to order other Isadore articles because of this size/cut issue.

    • 100% Merino SL Baselayer - Too short! (100% Merino SL Baselayer Crushed Berry)

      Daniel C, Germany, 9.1.2019

      Nice looking, good quality, and probably good functionality. But a terrible fit! It is way too short! All my Isadore jerseys fit perfectly (XL for 194cm, 92kg), but the baselayer doesn't work at all for me. The baselayer is shorter than the jerseys, and as its 100% Merino, it's riding up on your back leaving your lumbar section exposed. I my opinion, baselayers should be could rather long, as they worn under the bibs. If you are rather short and/or don't mind your ass and lower back not being covered by anything but the bib, the baselayer might be ok. If you are tall and/or want the baselayer to cover more, stay away.

    • merino žerú mole (100% Merino SL Baselayer Grey)

      Eduard, Slovakia, 13.10.2018

      do chladnejšieho počasie je to dobrý doplnok, len treba dať pozor že 100% merino chutná aj moliam, keď som ho po lete vytiahol zo skrine mám ho trocha sieťkované :D

    • leider schnell kaputt (100% Merino SL Baselayer Grey)

      Francesco, 19.8.2018

      Ich habe seit dieser Saison mehrere Teile von Isadore und bin von der Optik und der Qualität eigentlich begeistert. Auch dieses Unterhemd trägt sich toll. Ich habe es jetzt ca. 5-10 mal getragen und habe nun ein Loch im Brustbereich, welches sicher nicht mehr kleiner wird. Ich habe das Unterhemd immer mit der Hand und Merinowaschmittel durchgespült. Ich bin etwas traurig, dass es nur so kurz gehalten hat. Es ist immerhin nicht gerade günstig.

      Isadore Team


      Dear Francesco, sorry to hear about the defect in the fabric. Please contact us at info@isadoreapparel.com to arrange replacement. Many thanks, Natalia from customer service.

    • Looks good but the durability is poor (100% Merino SS Baselayer Grey)

      Nick Wang, Taiwan, 8.2.2017

      it's a race cut fit, that holds body well. however, i do not like it got wrinkled, side seams were twisted and a small hole on chest near decoration after the first wash. i always throw my cycling kits into laudry bag. it's kind of disapointed though.

      Isadore Team


      Sorry to hear about the trouble with baselayer.
      Our customer support will contact you and try to solve this to your full satisfaction. Thank you

    • Great but a question of durability. (100% Merino SS Baselayer Grey)

      Jeffrey Bell, Australia, 16.4.2016

      A really excellent baselayer, warm and effective on brisk Melbourne mornings, great fit as well. Only problem is after first wash got a number of holes in random locations, washed on light setting, top loader as per directions with a wool & delicate detergent along with similar cycling delicates..
