Nemo Verve 30 Sleeping Bag Jennes Blue/Keylime- Long. A mummy bag makes sense when you’re huddled up in a snow cave in the dead of winter, but when you’re sleeping under the stars on a cool summer night, there’s no reason not to have a sleeping bag that gives you some room to move around and relax. With a Spoon shape that balances warmth and comfort, Nemo Equipment’s Verve 30 Sleeping Bag lets you roll from side to side and features an integrated Blanket Fold at the head opening, giving your arms a place to rest outside of the bag. 40D nylon ripstop with DWR finish. Stuff sack and storage bag included.
