Sea to Summit Backpacking Sleeping Bags Micro Mciii 28 Sleeping Bag (850 Down)-Long-Left 033LL. These bags incorporate their 2D NanoShell providing the lightest most breathable water resistant shell.


The Sea to Summit Micro MCIII Sleeping Bag is a 28 degree sleeping bag for ultralight backpackers. The Micro MCIII is packed full with 850+ RDS-certified, ULTRA-DRY Goose Down, treated to provide water resistance so you can worry a little less about wet weather. The 2D NanoShell surrounds the down, protecting it in its lightweight, breathable nylon. Ideal for spring, fall, and winter trips, the mummy shape converts to a rectangular shape at the bottom via drawcord at the foot. This allows for temperature regulation on warmer nights, giving your feet a bit of a breather. The whole bag compresses down super small, taking up less space in your backpack so you can bring along that extra layer or more food. Yum, extra snacks.
