  Perfect base layer for autumn/spring

  Amazing base layer, keeps your body warm & dry. Used in combination with a normal jersey on rides with 13-15°C and it was perfect.

  Nice product

  I just started using these base layers and the first thing I noticed is they're soft and warm, perfect for late fall to early spring, they may be too hot for summer. The fit is good but a bit too long for me, I got an M and am 5'6" 148lb. But I like them and see me using them on colder days. For summer I will look for the lighter version of these

  Soft and perfect fit

  Excellent base layer. First time trying this brand so I think I’ll try some other items now that I can see/feel the quality.

  Perfect for cooler days

  Merino baselayer is perfect for Spring rides. Very soft and stretchy fabric that feels like you didn't have it on, except for the added warmth that feels really nice this time of year.

  So much comfort

  I have been using this underlayer now for a couple of rides. All the plastic/polyester underlayers made my skin itchy. This merino is super comfy and soft. Cold wash and its good to go for the next run. Isadore is a new brand for me but super hyped about the quality. Im 185 84kg and size medium fits perfect.

  Wie immer sehr gut

  Der stoff ist sehr angenehm zu tragen scheint auch ein anderer feinerer zu sein wie die Baselayer T-Shirts . Dadurch konnte ich eine größe kleiner nehmen da er flexibler ist. Stinkt nich verarbeitung Top. Als Jahrelanger Kunde kann ich die Produkte weiter empfehlen.

  Wonderful baselayer

  Very well made shirt with nice detail on the collar. I’m 1.63 and 73kg and S is a tight but good fit, length is good too. Material feels soft on the skin.

  Très bien

  Porté 3 ou 4 fois. Rien à dire sur la qualité. Taille S pour 1m78 et 68kg et c’est parfait, aussi bien coté longueur qui descend bien sur le bas des hanches que sur la largeur quand on aime que ça tienne bien le corps.

  We treated ourselves to the Women's Merino Sleeveless Baselayer Sulphur Spring 1.0 and Merino Sleeveless Baselayer Golden Oak 1.0 and are totally thrilled. The workmanship is great and it wears like a second skin! We almost only wear (merino) wool on skin and have various well-known manufacturers in our wardrobe. We are curious to see whether it will stand the test of time. You should definitely support Isadore: great service, fast shipping, lovely packaging, the quality and the colours are simply amazing.

  Merino Base Layer feels great

  My skin is very sensitive to wool in general but merino top this is brilliant.... Nice colour too. Great under my Spring jacket. It was a bit chilly out but my core stayed very warm. Perfect. I bought a M, but turned out too big, but not an issue. I've bought another one in a different colour and Small.

  zunächst einmal gefällt mir die Firmenphilosophie, Stichwort Nachhaltigkeit, umweltfreundliche Verpackung etc. habe mir das SL und das Kurzarm-Shirt SS plus das Deep Winter Baselayer jeweils in Größe XL gekauft. Bin 187 cm und bringe muskulöse 88 KG auf die Waage. Die beiden Kurzarmshirts passen wie eine zweite Haut, fühlen sich super-angenehm an, bin schon jetzt begeistert. Ich mag den enganliegenden, kurzen Sitz/Schnitt. Wer es weiter mag sollte sich für eine größere Größe entscheiden. Das Winter Baselayer sitzt nicht ganz so körperbetont und ist deutlich länger geschnitten, reicht mir bis übers Gesäß. Ist jedoch nicht störend, dennoch hätte es hier vermutlich auch eine L getan. Sehr hochwertige Teile, klare Kaufempfehlung

  Fantastic!

  Fantastic base layer. You put it on yourself and you feel most probably the most comfortable material ever. You start your ride and you forget, that you have some base layer. You continue with riding.... you can see, that you are sweating, but you can't feel it. You feel just comfortable enough. This is the description of the good baselayer like this. + material is with very good feeling on the skin + sweat is wicking away + fast drying + unlike the baselayer with "holes," when you unzip your jersey or your jacket, you don't feel the colder air right on your skin - any

  100% Merino SL Baselayer - Too short!

  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.

  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

  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.

  Essential item in my wardrobe

  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

  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.

  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

  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

  angenehm zu tragen

  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!

  Light, Comfort & Function

  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.

  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.
