Assos Spring Fall Skin Layer woman base layer

Light insulation, seamless comfort, and full-arm coverage in a long-sleeve base layer complete with a female-specific cut for the colder conditions encountered in late fall and early spring. It’s crucial that our upper body gets an added boost against the elements during those cold fall and early spring conditions. The Spring/Fall LS Skin Layer underwear jersey has a completely revised design and an entirely new set of fibers compared to the iconic SkinFoil base layers. The weight is reduced by 8%.

Featured fabrics
A cool-weather-tuned blend of carbon and polypropylene yarns are employed to pull moisture away from your skin and insulate your core, keeping you dry, insulated, and comfortable from the outset.

The thicker Circular Seamless construction introduces a tubular knit that’s free of side seams, creating an ultrasoft, comfortable feel against the body. Our female-specific cut mirrors the body in the saddle, with raglan-cut sleeves continuing up to the neck for maximum range of motion.
