Three things stand out in the Sabre Gloves by Arc'teryx: the ultra-breathable Gore-Tex XCR technology, the durable top fabric with extra stretch for dexterity, and the anatomically constructed fingers.The Gore-Tex XCR membrane has the same trustworthy lightweight, waterproof qualities as Gore-Tex, but has been fine-tuned to add even more breathability. This means that when you're breaking a sweat to get first tracks on a powder day or digging for your ski after a full yard sale into 3 feet of snow, your gloves with help to regulate the temperature inside your gloves without freezing your hands after you start to cool down. Overlaying the back of the hand is Arc'teryx's Fortius fabric, engineered for durability and flexibility. As a lightweight spandex/nylon blend, the fabric gives extra stretch for optimal dexterity of the hand when you're trying to unfold and re-fold the resort's trail map or open your water bottle, but stays true to the Arcteryx quality toughness when you're in between a rock and a hard place (or tree).Still, the Sabre Gloves' real winner is the Tri-Dex Technology, where each finger is individually constructed to give the best articulation of your hand. Each finger flexes without resistance from the glove, giving you all the freedom to grab at the tiniest of zippers or button the tiniest of buttons without ever needing to take them off.
