Versa Mummy Sleeping Bag: 41F Down

Heading out on a late spring or summer backpacking weekend, the Exped Versa Mummy 41 Degree Down Sleeping Bag offers ultralight warmth when temperatures drop off after sunset. Stuffed with 650-fill down, you benefit from superior warmth that packs down small in your bag, and it's sourced from ducks that have never been subjected to inhumane treatment. While the down may not be as beneficial if it encounters moisture, it's protected by a water repellent finish on the shell that helps ward off a light sprinkle or leaky canteen. Gear loops at the foot and center make for easy hanging when you need to air it out.

The Versa features plenty of details to make sleeping through the night more comfortable, even with temperature fluctuations. The generous hood is large enough for a pillow, and it cinches down tight to trap your body heat on chillier nights. A mummy shape and specific baffle design offer the most efficient warmth, but a two-way zipper means you can ventilate if you find the night balmier than expected.
