Expedition Performance

Trusted by backcountry athletes around the globe, [ak] delivers field-proven performance when it matters most.

Waterproofing, warmth, and mobility for optimal performance in the harshest conditions.

Engineered to Perform

[ak]® is more than a high performance line, it’s reliability when you need it most. A culmination of years of rider-driven development and backcountry exploration, this collection is engineered with features and technology to keep your mind on the journey instead of your gear.

Stormproof Protection

Dependable protection from rain, wind, snow, sleet, and everything in between. In harsh conditions, GORE-TEX outerwear isn’t a bonus feature, it’s a necessity. [ak]® jackets, bibs, and pants deliver relentless waterproofing without sacrificing mobility or breathability to keep you dry and ready for deep snow and stormy days.

Skin-to-Shell Warmth

Staying safe in extreme weather starts with what you're wearing. [ak] offers a system of layers with options for base, mid, and shell protection that work together to keep you warm, dry, and safe. Shed a base layer while climbing or add a GORE-TEX shell on the ride down to ensure comfort throughout the mission.
