The Alpinestars Stella AST-1 Pants are based off the popular men's AST-1 pants. The Women's AST-1 pants are a great option for the lady rider who needs waterproof protection in a lightweight and tailored riding pant that will pair up with any Alpinestars Stella riding jackets. The AST-1 pants are constructed of ballistic nylon and poly-shell for durability, protection and weight and feature a waterproof, breathable membrane for protection from wet weather. For impact protection, the AST 1 pants have CE approved knee protectors and internal hip PE comfort foam. The waist has a dual cinch for tailoring fit, and has a zipper and sliding hook for a secure closure. Zippered boot gussets seal out the elements and facilitate fitting and removal. These are for motorcycle riders. These are adjustable, posted pics of the Velcro at the bottom of pants and the waist.
