The UltraTek 730 down sleeping bag is designed to shelter you from the cold sting of alpine conditions. Lightweight and durable, it combines a mummy shape design and RDS 750 fill power down insulation to create comfortable protection down to -11°C. The bag construction also enhances thermal efficiency through trapezoidal baffling, a cantered foot box, and a 3D hood design with face baffle. The Pertex® fabric shell provides wind and water resistance, and is also treated with a Durable Water Repellent (DWR) finish for an extra barrier from the wet. Inside, the down is treated with DownTek™ to shield it from moisture and prevent clumping, allowing it to continue insulating even when ice or snow is present. For additional comfort, both the hood and neck baffle can be tightened to minimise warm air escaping. For storage and travel, both a compression sack and storage sack are included.
