A bad sleeping bag means a bad night. A great one means you actually want to go camping again. The market is full of options from $30 to $600 and the difference matters.
Our Top Picks
1. Kelty Cosmic 20 — Best Overall Value
Kelty consistently makes gear that punches above its price. The Cosmic uses CloudLoft synthetic insulation that dries faster than down and works in damp conditions where down loses effectiveness. At 20 degrees it covers most three-season camping.
- 20-degree rating covers three seasons
- Synthetic insulation works when wet
- Snag-free zipper with draft collar
- Available in regular and long lengths
2. TETON Sports Celsius 0 — Best for Cold Camping
For campers who go out in fall or early spring, the Celsius 0 offers serious warmth at a fair price. The double-layer zipper draft tube keeps cold air from sneaking in and the brushed interior is comfortable against skin.
- Rated to 0 degrees Fahrenheit
- Double-layer draft tube keeps cold air out
- Brushed flannel interior
- Right and left-hand zipper options
3. Coleman Brazos 20 — Best Budget Pick
Under $50 and works for warm-weather car camping. The flannel lining is comfortable and the mummy shape retains heat well. Not going to win awards for packability, but for a car camper who goes out a few times a summer it is perfectly adequate.
- 20-degree rating
- Flannel lining for comfort
- Mummy shape for heat retention
- Available in multiple sizes
4. REI Magma 15 — Best Down Bag
850-fill power down, 1.5 lbs, warm to 15 degrees. The Magma packs to about the size of a Nalgene and will keep you warm in three-season conditions with room to spare. REI’s version of the premium lightweight down sleeping bag at a more reasonable price than the boutique brands.
- 850-fill power down insulation
- 1.5 lb total weight
- 15-degree rating
- Packs to Nalgene-bottle size
5. Teton Sports LEEF Lightweight Sleeping Bag — Best Ultralight Budget
A 20-degree sleeping bag under 3 lbs for under $80 is unusual. The LEEF is synthetic, packs reasonably small, and works for backpacking trips where you do not want to spend $400 on a down bag. Good starter option for new backpackers.
- Under 3 lbs for a 20-degree rating
- Synthetic insulation works in damp conditions
- Budget-friendly for new backpackers
- Right and left-hand zipper versions
How to Choose
Temperature rating. Buy 10 degrees warmer than the coldest night you expect. Ratings are often optimistic. A “20 degree bag” for a 20 degree night means you survive, not that you sleep well.
Down vs. synthetic. Down is lighter and packs smaller. Synthetic insulates when wet and costs less. Car campers rarely need down. Backpackers in dry climates benefit from it.
Mummy vs. rectangular. Mummy bags are warmer because there is less dead air space to heat. Rectangular bags are more comfortable if you move around a lot at night.
FAQ
What temperature rating do I need? Summer camping: 35-45 degree bag. Spring and fall: 15-25 degrees. Winter camping: 0 degrees or colder.
Should I get down or synthetic? For dry conditions and weight savings, down. For wet climates or budget camping, synthetic works fine.
How do I store a sleeping bag? Never store it compressed long-term. Use a large storage sack or hang it in a closet. Compression damages insulation over time.
