Any serious adventurer taking on the mountains needs the UltraTek 900 down sleeping bag in their gear. It features a mummy shape design, which minimises bulk and reduces air pockets, and RDS 750 fill power down insulation to deliver a lightweight, high performance bag that can withstand ice, wind and snow. The down is treated with DownTek™ to shield it from moisture and prevent clumping, allowing it to continue insulating down to -17°C when dampness is likely present. The bag construction is also engineered for superior thermal efficiency, with trapezoidal baffling, a cantered foot box and a 3D hood design with face baffle. The Pertex® outer fabric and Durable Water Repellent (DWR) finish enhance both wind resistance and water resistance. For additional comfort, the hood and neck baffle can be tightened to help trap warm air inside. A compression sack and storage sack are included for storage and travel.
