Alpinestars Stella Flex-Ast Explorer

The Alpinestars Stella Explore Ast motorcycle trousers are purpose-built for women who demand lightweight performance in hot-weather tour-adventure riding. Designed specifically for the female fit, these trousers combine breathable stretch construction with impact and abrasion protection, without unnecessary bulk. The outer shell uses a breathable, stretch fabric that moves naturally with you on and off the bike. Strategic stretch ripstop reinforcements at the knees and seat increase durability in high-wear zones, improving abrasion resistance where you need it most. The result is a balanced combination of flexibility, resilience and long-distance comfort.

In terms of protection, the trousers are CE Certified AA, offering a high level of abrasion and impact performance for serious touring and adventure use. Integrated Nucleon Flex Plus CE Level 1 knee protectors and Bioflex CE Level 1 hip protectors deliver lightweight, flexible impact absorption. The protection remains low-profile and ergonomically shaped, so you retain natural movement and long-distance comfort. Adjustable knee protector positioning ensures precise alignment for optimal coverage in the riding position.

Practicality is equally well considered. Ergonomic zippered cargo pockets provide secure storage for essentials, while the external knee protector access system allows quick and easy removal when off the bike. A long zippered lower-leg opening makes fitting over various types of motorcycle boots straightforward, and integrated belt loops allow you to fine-tune the waist fit.
