The Samaya2. 0 is a true featherweight mountaineering tent thanks to its premium materials and single-wall construction. This 4-season tent features 43g Dyneema Composite on the floor and 34g Dyneema on the removable roof for an extremely lightweight and abrasion-resistant build. The walls feature a 3-layer Nanovent membrane which is highly breathable (40000 g/m2) and waterproof (10000mm) to keep out rain and snow while transmitting evaporated moisture from inside the tent to the outside air. The tent also features a zippered vent for increased airflow and reflective guylines to secure the tent in storms and windy alpine conditions. The Samaya2. 0 packs down into an 8X6 pouch with a trail weight under 3 pounds.
