Alpinestars Ast-1 Short Waterproof Textile Trouser

The alpinestars AST-1 v2 is a pair of lightweight motorcycle trousers with a waterproof and breathable Drystar membrane. They are designed without a bulky thermal liner.

Features include reflective detailing and hook and loop waist adjustment. The UK waist sizing guide gives M as 32, L as 34, XL as 36, 2XL as 38 and 3XL as 40.

Alpinestars garments can fit smaller than other brands, so a size up from a previous motorcycle trouser may be needed to allow for thermal clothing. The size guide is only a guide and cannot determine an exact size.
