Ultralight Down Sleeping Bag

Conquer the Cold with Ultralight Down Warmth

When your adventures take you into cold environments, a reliable sleeping bag isn't a luxury. It's essential. This high-performance mummy sleeping bag is engineered for those who demand serious warmth without the weight. Filled with premium duck down and designed for thermal efficiency, it's the perfect companion for winter camping, mountaineering, and cold-weather backpacking.

Features

• Premium Duck Down Insulation At the heart of this bag is high-loft duck down, nature's best insulator. It creates thousands of tiny air pockets that trap your body heat, offering an unbeatable warmth-to-weight ratio that synthetic fills can't match. It's incredibly light, warm, and compresses down to a minimal size.

• Thermally-Efficient Mummy Design The form-fitting mummy shape reduces excess air space around your body, meaning you warm up faster and stay warm with less effort. The bag features a deep, adjustable hood and a shaped footbox to prevent heat from escaping, cocooning you in warmth from head to toe.

• Choose Your Mission-Specific Model Select the right bag for your adventure:

  • 3-Season Model (300g Fill): An ultralight choice perfect for backpacking from spring to autumn, weighing approximately $900\text{ g}$.

  • Winter Model (600g Fill): With double the down, this model is built for true winter conditions and temperatures dropping well below freezing.

• Create a Double Sleeping System Don't adventure alone. This sleeping bag is designed for splicing—simply zip a left-zip model and a right-zip model together to create a spacious and incredibly warm double sleeping bag for you and a partner.

• Ultralight & Packable Don't let your gear weigh you down. This down sleeping bag packs into the included compression sack, shrinking to a surprisingly small size and freeing up valuable space in your pack.
