Campers and outdoor adventurers, this BISINNA mummy sleeping bag is seriously built for comfort in chilly conditions! It's rated comfortable down to 41°F (5°C), making it perfect for spring, fall, or cool summer nights. The 7-foot length comfortably fits users up to 6'1\ tall, with extra shoulder space and a stretchable footbox so you're not feeling cramped.

The adjustable drawstring hood seals in heat around your head, and the full-length insulated draft tube blocks chilly breezes from the zipper area. Speaking of the zipper, it's a smooth-gliding YKK 2-way zipper with anti-snag technology, so you can vent from the top or bottom for temperature control. At just 1.8kg, it's lightweight enough for backpacking, and it compresses down to a compact 15.7×11 inches using the included compression sack. You also get a mesh storage bag to maintain the loft between trips. It's machine washable, which is huge for keeping your gear fresh after multiple uses. Whether you're backpacking, car camping, attending festivals, or need emergency preparedness gear, this sleeping bag delivers reliable comfort and warmth. The quality features at this price point are honestly impressive - it feels and performs like much more expensive bags.
