Why this sleeping bag matters Keeps your head and body warm while blocking cold wind — designed for sleeping outdoors or in unheated spaces where drafts and low temperatures interrupt rest. Lets you control ventilation without removing layers, so you avoid overheating or sweating during changing conditions. Provides room to move and sleep comfortably rather than trapping you in a tight cocoon. Key benefits and how it solves problems Heat storage hood: the retractable, pulldown hat seals out drafts; the Ushaped hood shape traps warm air around your head for greater comfort in cold conditions. Adjustable ventilation: an independent zipper along the side lets you open or close the bag for controlled airflow. Easily finetune temperature without fully exiting the bag. Windproof and moisturemanaged: waterproof outer fabric combined with dense fibre fill creates insulation that resists wind. Breathable construction and moistureproof properties reduce condensation and keep insulation effective. Spacious envelope interior: envelopestyle layout gives a roomy inside that allows turning and comfortable sleeping postures, preventing the cramped feeling of narrow bags.

Breathable, moistureresistant construction to limit condensation and maintain comfort. Envelopestyle interior providing generous space for movement. Performance and compatibility Designed to provide windproof insulation and controlled ventilation for a wide range of outdoor and indoor sleeping situations.
