Arc'teryx Alpha FL

On ski tours (at least for me), the hardshell jacket spends almost the entire ascent either in or on my backpack. As I only wear it for the descent, I started looking around for a lightweight model without any frills and ended up with the Alpha FL from Arc'teryx. What was important to me was a robust, high-quality and relatively durable membrane, and the Alpha FL also uses Goretex Pro (in contrast to the Alpha SL, which is identical in terms of cut and details but slightly lighter, which uses Goretex Paclite), which promises long-lasting weather protection.
