Not just a simple baselayer, this is a thin high-performance midlayer, cut to ¾ length to fit with your ski boots. Our special Thermagrid material is unbelievably light and warm. Its micro-grid system makes it breathable, warm and stretchy. Thanks to a special antimicrobial treatment you will remain odor free and feeling fresh. Super-comfortable, these are designed for skiing but also ideal to relax in after a hard day on the mountain.
