All our bivouac tents feature a high-quality 3-layer laminate made from GORE-TEX®.
GORE-TEX® ARID LITE AIR is not only completely waterproof, windproof and moisture-permeable, but also extremely breathable and, above all, gas permeable. This means that our bivvy bags and tents can be completely closed off without you having to leave a vent open.
Oxygen and carbon dioxide exchange through the material, although you are fully protected against bad weather.
