Why We Like The Marmot Helium Sleeping Bag

The Marmot Helium Sleeping Bag stands out with its combination of superior warmth and lightweight design. It utilizes premium materials, starting with 800-fill goose down that offers exceptional insulation, enhanced by the Down Defender treatment to improve its resistance to weather conditions and maintain its loft for long-lasting warmth. Furthermore, the Helium features the Pertex Quantum fabric, known for its lightweight yet durable properties that contribute to the bag's impressively light weight of approximately two pounds.

The mummy shape of the Helium not only reduces weight but also maximizes heat retention, supported by the insulated draft tube and Nautilus Multi-Baffle Hood. Whether on backpacking trips or mountaineering expeditions, this sleeping bag's compact size and lightness ensure it won't weigh you down.
