Frequently Asked Questions

Is this sleeping bag suitable for winter camping in the US?

Absolutely. With a temperature rating of 5°F, this sleeping bag is designed for extreme cold conditions and will keep you warm during winter camping trips in the mountains, backcountry or any cold-weather environment.

How do I pack and store the sleeping bag?

The sleeping bag comes with a compression bag for easy transport. After use, ensure it's completely dry before storing loosely in a breathable storage sack to maintain the insulation's loft and longevity.

Can I wash this sleeping bag?

Yes, but we recommend hand washing or using a large-capacity washing machine on a gentle cycle with mild detergent. Avoid fabric softeners and tumble dry on low heat or air dry completely before storing.

What's the difference between a mummy bag and a rectangular sleeping bag?

Mummy bags are tapered to follow your body's contours, which minimizes air pockets and maximizes heat retention. They're lighter and warmer than rectangular bags, making them ideal for cold-weather camping and trekking.

Is the sleeping bag waterproof?

The outer shell is made from water-resistant 190T polyester taffeta, which protects against moisture and light rain. However, for prolonged exposure to wet conditions, we recommend using a waterproof bivvy bag or tent.

What height range is this sleeping bag suitable for?

The mummy design accommodates most adults up to approximately 6'1" comfortably. The tapered shape ensures efficient heat retention for a range of body sizes.
