CHOOSING YOUR ULTRA TRAIL JACKET

Warmth, protection and breathability

In ultra, conditions change without warning: cold at altitude, light rain, dry heat, icy wind. That's why we've designed a range of jackets adapted to each season and each intensity.

Choosing the best solution for your running practice revolves around three criteria: thermal protection, waterproofness, breathability.

Whatever the weather, our solutions are designed to meet the demands of ultra and touring, without compromise, combining comfort and performance.

THERMAL PROTECTION
Adapt to the intensity of the effort and the temperatures. An insulated jacket becomes essential for cold or high-altitude outings or a lighter model to avoid overheating.
IMPERMEABILITY
Cope with all weather conditions Choose a 3-layer waterproof membrane to protect against the risk of storms or prolonged rain, or simply an ultra-light, water-repellent windbreaker.
BREATHABILITY
Evacuate heat and humidity regardless of the intensity of the effort An ultra-light and breathable jacket to wick away heat from intense exercise or to opt for the comfort of a more protective material.
