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.

Breathability:
- Especially for fast-paced activities, you need breathable clothing that regulates your body temperature, wicks away sweat, allows air to pass through, and so keeps you comfortable.

Durability:
- For your garment to last you a long time despite plenty of abrasion or rock contact, it has to be hard-wearing. Do you weigh every gram and define absolute freedom of movement as the most important characteristic? Then less abrasion-resistant, lighter clothing can be an advantage.

Packability:
- On multi-day adventures or other activities with a lot of equipment, space in the backpack is at a premium. Similarly, for those aiming to travel fast and light, packability is essential. This factor may be less relevant if protection and durability are the top priorities.

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.

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.
