Marmot Kids' Nanowave 40° Sleeping Bag

Brand: Marmot

Whether it's a bike trip to the beach or a campout in the backyard, kids will be able to stuff the Kids' Nanowave 40 Sleeping Bag in their backpacks and stay warm and comfortable all night long. Spirafil™ high-loft insulation's unique blend of large, spiral hollow fibers and small polyester fibers provides the exceptional warmth, softness, and compressibility of natural down while increasing moisture resistance. The anatomically shaped footbox minimizes heat buildup and gives kids plenty of room to get comfortable. The bag’s top portion is built for maximum loft and warmth, while the bottom portion retains a blanket-like feel for all-night comfort. Rounding out this adventure-ready sleeping bag are “feely” draw cords, dual hang loops, and a stuff sack that compresses for convenient packability. This bag is ideal for people under 5 feet tall.
