Seamless reinvented This is our softest & most comfortable base layer yet. Weve worked with state of the art seamless knitting technology to make a base layer thats so comfortable on the skin that youll be amazed. But its also due to this new texturized polypropylene fibres that mechanically transport moisture away from the skin to the nylonlayer where its transfered outward. Even the smallest details are just right like the ultra soft thumb loops that hold the sleeves in place & cover that gap that always forms between glove & jacket.
