Down fears moisture, ordinary cotton is bulky and easy to collapse, and artificial fleece has poor air permeability. PrimaLoft perfectly fixes all these drawbacks.

It serves both beginner skiers and advanced alpine & powder snow enthusiasts. If you pursue durable and weather-resistant skiing experience without bulkiness and cold troubles, PrimaLoft-equipped ski gear is undoubtedly a reliable choice.
