Description from Helly Hansen: "Hardwearing pants for shredding freshies Durable synthetic materials for quick-drying performance Breathable membrane provides light waterproof protection Synthetic insulation at seat and knees for warmth where its needed. Better layered Adjustable waist provides a secure, customized fit Articulated knees increase range of motion Integrated gaiters stop powder from packing in Zippered thigh pocket has D-ring for securing your beacon." Note: Slight scuffs on the inside cuffs from ski edges. Visible in photos. I can repair them, but then firm on price. They don't really affect the pant performance as-is, because the scuffs are over the boot cuffs.
