The men's Dynafit Blacklight Thermal jacket is an extremely lightweight and technically advanced solution designed for fast ascents, ski touring, and demanding alpine tours. Thanks to the innovative Octa® Silver material with its unique hollow-fiber structure, this jacket delivers superior thermal insulation while maintaining an exceptionally low weight and high breathability that prevents overheating during high-intensity sports activities.

The construction features a Jersey Bistretch outer layer providing full 4-way stretch and unrestricted freedom of movement at all times. The material composition combines 100% polyester (47% of which is recycled) on the inside with a blend of 71% polyamide and 29% elastane at the hem for a secure, comfortable fit. With a total weight of just 281 g, the jacket is lightweight and packable, making it perform exceptionally well as a reliable midlayer.

The design is completely dedicated to mountain functionality: a close-fitting hood provides reliable wind protection, while elastic hems and cuffs effectively prevent heat loss. Two carefully designed front zippered pockets are positioned to allow easy access even when wearing a backpack or climbing harness, underscoring the well-thought-out mountaineering character of this garment.
