  • Soft on touch
  • Excellent perspiration and wicking

    This piece of garment is one of the key parts of every rider’s wardrobe. In times when the temperatures drop, it can be combined with top layers to make you feel comfortably warm. Combining the natural characteristics of Merino wool, they are odor resistant and have excellent perspiration wicking and thermoregulation.

    Constructed from 180g/m 100% Merino Wool fabric.

    Comes in many colour variations: black, flecked grey, Atlantic Blue, and Golden Oak.

    Super comfortable

    Slim fit is comfortable enough to feel free when moving and Merino is soft on touch and itch free. We removed any labels and tags to avoid discomfort.

    Race or comfort size

    Pick your regular size for slim performance fit. If you prefer comfort fit we recommend one size bigger.

    Easy care

    High quality and delicate material that deserves careful maintenance. We strongly recommend cold hand washing and strictly no tumble dryer.

    Proudly handcrafted in EU.

    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.

    • Perfect Styling

      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

      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

      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

    • 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.

    • smooth fit

      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.

    • 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.

    • 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

    • CD

      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)

    • angenehm zu tragen

      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!

    • 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.

    • Mr (Women 100% Merino SL Baselayer Grey)

      Robert Mitosinka, Slovakia, 31.8.2018

      Super kvalita. Velkosti su trochu nevyspytatelne medzi dlhym a kratkym rukavom ... M a M nie je celkom totozne.

    • Reinhard (100% Merino SL Baselayer Atlantic Blue)

      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

    • merino žerú mole

      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

    • 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.

    • leider schnell kaputt

      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.
