The Anatum Down 20°F Sleeping Bag is a fully featured, lightweight sleeping bag designed for backpackers and backcountry adventurers who want dependable warmth without unnecessary weight. Built with ultralight shell and liner fabrics, the Anatum delivers excellent packability while maintaining comfort and durability for nights spent in the mountains or deep in the wilderness.

Filled with 500-fill power RDS-certified duck down, this sleeping bag provides a strong warmth-to-weight ratio at an accessible price point, making it a great choice for hikers, campers, and climbers looking for reliable insulation in cooler conditions.

A #5 YKK® two-way zipper with dual tabs allows for smooth entry, easy exit, and adjustable ventilation, while the anti-snag zipper cover prevents fabric from catching during use. The zipper is designed to remain sleek and low-profile, so you’ll hardly notice it when it’s not in use.

The Anatum also features a segmented hood adjustment system with individual pull cords, allowing you to dial in the fit around your head for maximum warmth and comfort. A continuous zipper and hood baffle help prevent heat loss and eliminate cold spots along critical areas of the bag.

For added stability during the night, four sleeping pad attachment loops allow you to secure the bag directly to your sleeping pad, helping prevent shifting while you sleep.

The bag is finished with a PFAS-free water-resistant treatment, offering protection from moisture while maintaining environmentally responsible performance.
