Natural Merino fibers to keep you naturally warm

5 / 5
50 reviews

I have a drawer full of merino thermals I wear both off and on the bike. Most are 150 or 180gram weight. This one is 250gram and is the best by far. The sizing is tight to begin with but merino does loosen up with time. Some have commented that these are expensive. I disagree. If you can find a 250gram merino top at a better price I would be surprised and of this quality definitely not. Chapeau Isadore!

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.

  • Too short

    Roger Murer, Switzerland, 4.1.2022

    I am 78kg, 188cm with a chest of 100cm. I purchased in XL however arms and body are too short. However this Meriono-Shirt keeps you warm even when it is wet.

    I liked the product however I have a hairy chest and it was really scratchy for me to use it. I had to return it.

  • Comfortable but sleeves too short

    Stefan Zieg, Germany, 21.12.2018

    Just bought XXL (180/90) for Winter walks and rides, feels very comfortable und cosy. Unfortunately the sleeves are about 2-5 cm to short. Usually this is not a problem for me with other brands and the Ovada Deep Winter Baselayer Men in XL. Using the thumbholes helps a littlelittle bit. Please give some cms to the sleeves ;-), especially for winter.

  • Great product

    Eduard Winkler, Slovakia, 26.11.2021 (Merino Long Sleeve Baselayer Marsala)

    I'm enjoying wearing it even when I'm not going on bike. It's very confy and warm. On a bike is working well in cold, used only once, but was very happy with this product.
