Ostrya is a Montreal-based mountaineering brand that bridges technical performance with a progressive aesthetic—because gear that works shouldn't look like it came from a 1990s REI catalog. Founded on the belief that adventure living can respect the spirit of mountaineering pioneers while connecting art, culture, and mountain sports, they make functional garments built for alpinists, climbers, and backcountry skiers who care about innovation, self-expression, and discovery.

Their approach emphasizes durability and confidence in the mountains, whether that's ice climbing in the Laurentians or ski touring in the Rockies. It's mountaineering gear for people who believe the journey matters as much as the summit—and who want to look good getting there.
