What Our Gearhead(R) Experts Are Saying:"This is my favorite car camping bag when nights dip near freezing. It's roomy enough for side sleeping and turning over, but it still packs down surprisingly well. The draft collar is great for sealing in heat, and I love that the insulation and shell are made from recycled materials."We love slipping into the Tempo 20 Sleeping Bag after long campfire nights or early morning hikes. With its generous Classic Spoon(TM) shape, this bag offers space to move at the elbows and knees, making it perfect for side sleepers or restless campers. It's a cozy retreat for crisp shoulder-season overnights, and packs smaller than most traditional rectangular bags, so we can stash it easily in the trunk. This updated version uses 100% post-consumer recycled Zerofiber(TM) 650 synthetic insulation to trap warmth and resist moisture, and NEMO's PFAS-free polyester shell supports a lower-impact footprint. The plush Blanket Fold(TM) draft collar helps seal in heat like our favorite comforter, and the integrated sleeve makes a great spot to stuff a jacket or pillow. Whether we're camping at a festival or pulling up to a mountain basecamp, the Tempo is warm, comfortable, and responsibly built.
