Alternative Long Sleeve Baselayer 1.0
For those winter rides where the cold is relentless, the Alternative Long Sleeve Baselayer works to prevent sweat buildup which helps to keep your body from alternating between heat and chills. The 100% recycled materials are good for your body and great for the environment.
Now with an updated fit, the Alternative Long Sleeve Baselayer is made for autumn-winter riding and works to keep the body temperature well-regulated and the skin dry. It is a piece of clothing that accomplishes this with a snug, second skin feeling, and is so comfortable that you will forget you are even wearing a baselayer. The long sleeves pair well with one of our long sleeve jerseys and help ensure your arms will not suffer from biting winds. The fabric has been knitted from material that has been made from recycling waste products, and in compliance with the GRS International Certification. The printed design is stylish and understated. Extremely easy to wash and care for.

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.

Luxurious base layer with a compressive fit
I ordered up a size to my usual Isadore fit and glad I did as this has a compressive fit. Great looking base layer with a silky feel and works perfectly. I've used it on cold Spring days as it seems to have a good temperature range.Show full review -

Alternative Long Sleeve
This is my comment to the long sleeve shirt: It is thicker than the short sleeve summer shirt. It feels very nice on the skin and protects very well on cold rides with a long sleeve jersey. I am 188cm/78k - chest 100cm and ordered XL it sits nice on the body without being tight. The sleeves could be 2 to 3cm longer, but since it is a base layer it works as is. I'd purchase an other one right away.Show full review
