The Mountain Studio 3L Hybrid Mens Shell Jacket 2026

Hybrid shell jacket built for freeride and backcountry skiing. The Z-5 jacket features The Mountain Studio’s proprietary ALP-3 membrane technology, combined with 20g lightweight insulation. The jacket is light and durable, like a shell, with just a touch of insulation that makes it a perfect hybrid for any day in the mountains.

The ALP-3 technology is a PFAS-free, hydrophilic membrane that delivers some of the best waterproof and breathability ratings in the industry, combined with a stretch fabric for enhanced mobility and comfort. The jacket features two large chest pockets, alongside two hand pockets, to store essentials while out on the mountain. Underarm ventilation zippers allow for quick airflow adjustments and the release of excess body heat. An internal snow skirt keeps wind and fresh snow from sneaking in from underneath, cooling you down. A large, helmet-compatible hood adds an extra layer of protection from the elements when needed.

The Z-5 jacket is the perfect choice for the resort-based and backcountry skier who needs full coverage against all imaginable weather conditions.
