In our outdoor world, not all shell fabrics rate the same, which is why we decided to set a Stio standard for mountain-rated protection you can trust when rough weather descends. Our new PeakProof rating ensures a Teton-tested level of waterproof technology and breathable comfort for elevated action in mountain environments.

Entrant™ is a lightweight 50 denier waterproof/breathable plainweave fabric that offers durability, a soft hand and mechanical stretch. With a 20,000 mm waterproof, 13,000 g/m2 breathability and hydrophobic microporous membrane, it provides quick response to weather related changes and an ideal balance between waterproofness and moisture permeability.
