Rehall says about the Croob-R
The CROOB-R is our most technical men's snow pant. All visible zippers are waterproof, the outer shell fabric has a 20K/20K water resistance and the inner lining fabric is made out of 100% Polyester. This two-colored pant with contrast zippers has a normal fitting, reinforced fabric on the bottom hem of the legs and on the inside hem of the legs there's a snow skirt to keep out unwanted snow.
