Western Mountaineering Summerlite Sleeping Bag: 32F Down Cranberry, 5ft 6in/Left Zip

The Summerlite 32 Degree Down Sleeping Bag is Western Mountaineering's lightest bag with continuous baffles, ideal for backpacking anywhere from nearby lakes to the faraway alpine.

This mummy bag achieves a phenomenal light weight through its 850+ down insulation, the loftiest down available on the market.

Western Mountaineering wrapped up this ultralight insulation with a water-resistant ripstop material, which Western Mountaineering claims is the lightest downproof fabric out there.

The shell's water-resistance helps the insulation retain its lofty warmth in moisture-riddled environments.
