A high-performance ski mountaineering race suit designed in collaboration with the Spanish National Skimo Team, with the goal of delivering maximum performance at the Olympic Games. Developed to meet the highest competitive demands, it combines lightweight construction, ergonomic fit, and advanced functionality.

Made with AeroSkin fabric, featuring four-way stretch, it adapts perfectly to the body, providing maximum comfort, freedom of movement, and optimal thermal regulation/breathability in extreme conditions. Weighing just 319 grams, it is possibly the lightest suit on the market.

It includes a double elastic pocket for quick access to climbing skins and an inner zippered pocket to securely store essentials without compromising aerodynamics.

The ankle area is reinforced with ultra-light and durable Dyneema® for increased durability, while an upper band and an interchangeable elastic strap ensure a precise fit over the boot, preventing snow from sticking and creating a "clog" effect.

Moreover, a strategically designed rear opening allows compatibility with any ski boot fastening system. A 100% FAST&LIGHT garment, meticulously engineered for top-level competition, optimizing every detail for maximum speed and efficiency on the snow.
