FINGERSCROSSED guarantees a new dimension of comfort and freedom of movement. PROLEN® is the lightest fibre ever developed, with a density lower than water, 50% lighter than cotton. PROLEN® clothing is the lightest so far on the market.

Resistant to abrasion, tension and tearing. PROLEN®'s resistance to wear is 2.5 times that of cotton or wool. PROLEN® garments withstand bad weather, sun, sweat and moisture very well. Thanks to the fact that the yarn is dyed with a drum dye  Prolen is dope-dyed or mas dyed, i think drum dye is sth different , the racing socks remain colourfast even after repeated washing. The colour does not migrate to your skin.
