Kelty Supernova 0 Degree Down Sleeping Bag (Long) – Compact, Roomy & Eco-Friendly 2024

Meet the Kelty Supernova 0 Degree Long

The Kelty Supernova 0 Degree Down Sleeping Bag in Long size sits between casual campground nights and backcountry treks. It combines a compact footprint with a roomier silhouette to fit a wider range of body types and sleeping positions. Inside, lofty baffles cradle 550 fill power down for warmth and loft, while buttery-soft fabric resting against the skin adds a gentle, comfortable feel on chilly nights. An anti-snag zipper with locking sliders gives you controlled venting and easy adjustments as temperatures shift from evening cool to early morning chill.

Designed for versatility

Whether you’re solo under the stars or sharing a campsite with a partner, the Supernova adapts to real-world nights out. If you want extra space, you can zip two bags together to create a 2P sleeping haven, with room for two full-sized pillows and plenty of wiggle room for different sleeping positions.

Eco-conscious design

Kelty’s ongoing recycled materials program now includes recycled fabrics in both liners and shells, helping reduce environmental impact while you enjoy outdoor adventures.

Technical details that matter

Zero-degree Long size is designed to fit sleepers up to 6 ft 6 in, with an interior roughly 81 x 34 inches. The bag uses 550 fill power gray duck down with RDS certification, and it weighs about 4 lbs 13 oz when packed. When stored, it compresses to a compact 17 x 10 inches in the included stuff sack.

Why this bag might fit your trips

Lofty baffles and buttery-soft fabric create a cozy feel on colder nights, while a lightweight yet warm construction helps keep your pack manageable.
