Warmth-to-weight ratio: - Even when every gram counts on the trail, you need clothing that provides reliable warmth. A high warmth-to-weight ratio means lots of warmth with little weight. Lightweight: - We design every product with performance in mind. That´s why weight, in combination with functionality, always plays a major role. The lighter the style, the freer and more agile you can move. The more durable and dense it is, the more protection it offers. Quick drying: - To prevent you from losing heat during a break at the summit, your clothing must wick sweat and moisture away from the skin and allow it to evaporate quickly. The more you sweat during an activity, the more important it is for it to dry quickly and have breathability. Stretchability: - Outdoor clothing must not be constricting. It must be elastic without losing its shape and should give you maximum freedom of movement. The more flexibility your activity requires, the more important stretchy material is.
