Alpine environments calls for durable layers that move with us, which is why we like the ORTOVOX Brenta Short. The nylon face fabric is highly abrasion-resistant with elastane stretch to secure more freedom of movement for our climbing moves and fast-moving approaches. The short is also lined with a blend of polyester and merino wool to wick moisture away from our skin to keep us drier and more comfortable as we exert more energy moving up the mountainside.
