The Castelli Iride Seamless Long Sleeve Base Layer for men is Castelliís softest
and most comfortable base layer yet. They worked with state-of-the-art seamless
knitting technology to make a base layer thatís so comfortable on the skin that
youíll be amazed. But itís also due to the new texturized polypropylene fibers
that mechanically transport moisture away from the skin to the nylon layer where
itís transferred outward. Even the little details are just right like the ultra
soft thumb loops that hold the sleeves in place and cover the wrist between your
jacket and glove.
for comfort. Polyester/Lycraģ for excellent wicking. Thumb-loops.
