shelterTX™ 1 (bluesign®-approved)
An extraordinarily waterproof, breathable and robust outer material. The laminate lets condensation dissipate and offers excellent protection against damp from outside material.
enduranceTX™ 3 (bluesign®-approved)
Very durable, water-resistant nylon ripstop material with PU coating. Ripstop fabrics are made by weaving a nylon thread in interlocking, crosshatched patterns through a base material. (You can spot its distinguishable appearance in fabrics with a raised box or diamond pattern.) This reinforced construction prevents rips and tears from spreading across the fabric, increasing their ability to withstand abrasion.

I used this bivi inside of the tent during a multi day mountain trip to keep my sleeping bag dry from the condensation. In that regard it performed really well and my bag stayed dry. I haven't used it yet as a solo bivi bag as I always bring my tent with me. The only annoying thing about this Bivi is that it is not that easy to fold it back into its pocket because of the air which enters during the folding. To minimize that, I usually first fold it starting from the pocket (opposite side) to the top of the Bivi so that the air can escape. After that, while unfolding it bit by bit, I fold the other side of it and finally insert it into it's pocket. When packed, it has really minimal dimensions so there is no reason why I wouldn't bring it with me to any of my further trips to the mountains.
