Mountain Studio’s Hybrid Shell Bib pants are designed for both the piste and the backcountry. Built with our new ALP-3 fabric technology and 20g G-LOFT insulation, they combine the lightness and durability of a shell with just the right amount of warmth for any mountain day. The ALP-3 membrane provides impressive water resistance (30,000 mm) and breathability (30,000 g/m2/24 hrs). The 3L stretch fabric, made from nylon and spandex, ensures comfort and top performance, while the PFC-free DWR treatment adds protection. The 20g G-LOFT® evoX insulation uses next-gen 3D fiber architecture for exceptional warmth with minimal weight.
