    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.

      im around 78kg and 179cm tall. i compared M and L. Large is more comfy and looser. Medium fits really well, tight but still comfy. my built is muscular and i was afraid the medium would be tooo tight but its not. its just perfect. the material feels awesome, looks well made and the first ride in it was more then satisfiying. this will not be the last product of isadore.

    • Top baselayer

      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.

    • Light warm and breathable

      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

    • Simply Top

      Sascha Hartmann, Germany, 22.8.2017

      perfekte Passform - tight, long & stylisch ...

    • perfekt

      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.

    • Excellent baselayer but watch the sizing...

      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

      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

      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

      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 !!!!

    • Stylish second skin

      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.

      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

      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.

    • Nice cut and comfortable to wear

      Stephan, 31.3.2019

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

    • Comfy baselayer, great features

      Tomáš, Slovakia, 17.10.2018

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

    • Tight and comfortable

      Lukas, Slovakia, 2.9.2018

      This merino baselayer is absolutely great. Worth of the money.

    • Mr.

      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.

    • Perfect

      Paul Renson, France, 19.6.2018

      The base layer looks great and fits very well. Keeps the body at a comfortable temperature even for long and difficult rides.

    • Merino rocks!

      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!

    • Looks good but the durability is poor

      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.

      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.

      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..
