You never know what a summer evening will be like. The best hot weather sleeping bags should stand up to morning dew, nighttime temperature drops, and sticky humidity. Going to bed cool and waking up warm: That's what you need from a good bag.

Material can make or break your outdoor gear. At the risk of overheating, you'll need to look for features like a breathable lining and lightweight construction. It's always a good idea to look at the exact temperature range each bag is intended for before purchasing. To aid you in your search, here are 12 of the best sleeping bags for summer camping.

1. Patagonia Hardware-Free Lightweight Sleeping Bag, $199

The subtly insulated shell and lining with no hardware make this compressible sleeping bag a top pick for light packing.

2. Naturehike LW180 Lightweight Summer Sleeping Bag, $54.95

This ultra-lightweight material breathes and yet provides shelter from chilly morning dew. It's also made from soft nylon fabric that repels water.

3. Cocoon Silk Mummy Liner, $69.95

Sometimes the best hot weather sleeping bag isn't one at all, but a silk liner, which helps to regulate body temperature, is naturally mosquito repellent, and hypoallergenic. The sack is made to fit into a sleeping bag or be used on its own.

4. Outdoor Research Helium Bivy, $199

Skip the sleeping bag altogether on scorching nights and purchase a bivy bag. A single-pole system creates headspace within the enclosure, while a mesh window keeps nighttime bugs out.

5. Bessport 1-2 Person Sleeping Bag, $29.99

This is an affordable, warm-weather sleeping bag that works well in temperatures of 40-77 degrees Fahrenheit — and if it happens to hit 80 one night, simply open the bottom to let your feet breathe.
