The Beta Shell Mitten delivers complete waterproof breathable protection, is highly durable and has a level of dexterity not expected of a mitten. Durable protection comes from N333p-X 3L GORE-TEX® fabric with tricot technology on the palm and fingers. Combining proven GORE-TEX® weather protection with a burly N333p-X face fabric and laminated TPU reinforcements on the fingers and palms helps eliminate the need for a leather overlay. This reduces overall weight, and, as leather can absorb moisture, helps keep hands warmer. N70p GORE-TEX® on the back of the hand has a lighter weight face fabric for improved breathability. All seams are fully taped to create a shell that completely seals out water, wind and snow. Designed to be layered over an insulated liner mitten.


While mittens don’t offer the dexterity gloves do, it is still important that they work with the complexities of the human hand. The Beta Shell Mitten is constructed using Arc’teryx Tri-Dex™ patterning technology, a three-lobe finger pattern that specifically maps the thumb and finger box according to the hand’s natural grasping motion. Seams are minimized and placed so as not to interfere with grip. The result is a mitten with unexpected dexterity.


Features are selected for the realities of alpine travel and the demands backcountry skiers and snowboarders face. The short gauntlet fits under or over jacket sleeves; the elasticized adjustable wrist strap creates a secure seal and precision fit that keeps heat closer to the fingers; the gauntlet adjustments are easily operable with the mittens on, and removable leashes help prevent dropping. In freezing conditions, the Beta Shell Mitten systematically layers with the Primaloft® filled Atom Mitten Liner, or, in milder cold, can partner with the Rivet Gloves or Delta Mittens.
