The right sleeping bag makes the difference between a great night and a cold one. For spring-through-autumn camping, a 3-season bag rated around 20F/-6C is the sweet spot. Here are our picks for 2026.
1. Kelty Cosmic 20 — Best value down bag
Genuine down warmth at a synthetic-like price. Warm, reasonably light and the go-to recommendation for hikers on a budget.
2. REI Co-op Trailbreak 20 — Best all-round
Comfortable, durable and affordable synthetic insulation that shrugs off damp conditions. A dependable first bag.
3. Marmot Trestles Elite Eco 20 — Best synthetic
Warm, water-resistant synthetic fill with a roomy cut. Great for wetter climates where down is a risk.
4. NEMO Disco 15 — Best for side sleepers
A spoon-shaped design gives extra room at the knees and elbows, plus vents for temperature control. Ideal if you toss and turn.
5. Sea to Summit Spark — Best ultralight
Premium high-fill down in an astonishingly light, packable bag. The choice when weight is everything.
