Alpinestars ST-1 Waterproof Pants

Straightforward waterproof touring pants in nine sizes

The ST-1 Waterproof Pants are the matching half of the ST-1 WP Jacket: a 600D polyfabric shell with poly ripstop reinforcement on the inner legs, a fixed waterproof liner, and a detachable 80 g thermal liner that zips in for cold mornings and comes out for summer. The cut is a new active fit with pre-curved legs, 3D knees and a comfortable crotch construction. Knee armour is CE Level 1 Nucleon Flex Plus, sitting in a three-tier colour-coded pocket so you can set the height, and the garment is certified to EN17092-4 A class.

Sizing and fit

Nine sizes from S to 6XL, which makes the ST-1 one of the few waterproof pants that go this big. Zippered cargo pockets give you real storage on the thigh, and the streamlined construction keeps them looking like touring pants rather than adventure pants.

Complete the set

Made to pair with the ST-1 Waterproof Jacket. For gloves, the Andes v3 Drystar Gloves cover most of the year and the WT-1 Drystar Insulated Gloves cover winter.
