If you want a true summer bag (for mild nights above 40°F) that packs easy (less than two pounds and stuffable to bread-loaf size), but hesitate to overspend for a one-season bag, get the Swift. The price guarantees you won't have gear guilt, and the 750-fill down and roomy semi-rectangular cut assures you'll have a good night's sleep.
It compresses as well as more expensive bags, thanks to the premium down and a lightweight, 40-denier ripstop nylon shell. It even has a hood and a full draft collar that seals with a bungee cord, which boosts warmth for cold sleepers. Bonus: A stash pocket inside the chest area is bigger and easier to access than average. $135; 1 lb. 10 oz.; 40°F
