The Ortovox Ortler Gore-Tex Pant uses a 3-layer GORE-TEX PERFORMANCE fabric weighing just 86 grams per square meter, yet it holds a waterproof rating of at least 28,000 millimeters for the pant's entire service life. Dyneema-CORDURA reinforcement guards against sharp ski edges, and integrated gaiters with non-slip elastic seal out snow at the boot. A light carabiner secures an avalanche transceiver against loss, and side ventilation zippers dump heat on the climb. What Our Gearhead® Experts Are Saying:"I've caught my ski edge against this pant more times than I'd like to admit on a long tour, and the reinforcement holds up without a tear. That kind of durability from something this light is what lets me stop babying my gear."
