F1 LT MEN’S

Ultralight with uncompromising control, the F1 LT is built for demanding ski mountaineers and fast-moving backcountry athletes. Designed for long ascents and technical descents, it delivers exceptional efficiency without sacrificing stability. A Carbon Grilamid® LFT shell and cuff provide powerful stiffness at minimal weight, while the Speed Lock LT ski/walk mechanism offers a 72-degree range of motion for fluid uphill strides. The BOA® Fit System secures the lower shell for a precise, glove-friendly fit, and the Fast Buckle closure simplifies transitions between climb and ski mode. Inside, the Intuition® Tour LT liner delivers warmth and custom-molded comfort that adapts to your stride. A Vibram® UFO RS sole ensures reliable traction across ice, rock, and steep skin tracks.
