Alpinestars Explore AST Pants

Lightweight stretch adventure pants for hot weather

The Explore AST Pants are Alpinestars' warm-weather adventure pants: a fully breathable, stretch outer shell with stretch ripstop reinforcement at the knees and seat, cut with a casual style that works off the bike as well as on it. They're built for spring and summer trips and hot-climate touring rather than winter. Armour is CE Level 1 Nucleon Flex Plus at the knees and Level 1 Bio-Flex at the hips, both included, and the knee protectors sit in external pockets so you can pull them out when you're off the bike without taking the pants off. Certified to CE AA.

Sizing and fit

Sizes S to 4XL in two colourways: Black and Walnut/Black. Belt loops let you set the waist with your own belt, the knee armour is adjustable for height, and a long zip at the hem opens the leg to fit over boots or riding shoes. Zippered cargo pockets on the thighs. The same pants come in a short leg.

Match it up

From the jackets here, the Andes Air Drystar Jacket is the natural warm-weather match, or the Maxdura Drystar Armoured Shell if you spend more time off-road. Gloves: Mogress Airflow Gloves.
