Bollé Keystone MIPS Ski Helmet Unisex
Description
Built for riders who push into steep terrain and variable conditions, the Bollé Keystone MIPS delivers a clean, freeride-focused silhouette backed by serious protective engineering. Its ABS shell construction provides durable impact resistance while keeping overall weight manageable across long days on the mountain. The standout feature is the MIPS (Multi-directional Impact Protection System) — a low-friction liner layer that allows the helmet to rotate slightly on impact, reducing rotational forces transmitted to the brain. An integrated front brim cuts glare and wind without adding bulk, and an elastic goggle retainer locks your goggles in place so there's no gap between helmet and lens on fast descents.
The Keystone is offered in three matte finishes — Argil Matte, Black Matte, and Smoky Purple Matte — each with a low-sheen surface that resists scratches and keeps a refined, understated look on and off the lift. The matte palette suits riders who prefer their gear to complement rather than compete with their kit. Sizing runs across three options — Small (52–55 cm), Medium (55–59 cm), and Large (59–62 cm) — with a fit system designed to accommodate a broad range of head shapes, making this a reliable unisex choice for both skiers and snowboarders.Frame Specifications| Specification | Detail |
