BISINNA Cotton Flannel Envelope Sleeping Bag for Adults - 3-Season (75x33 in)

Cozy, roomy comfort for outdoor adventures

The BISINNA Cotton Flannel Envelope Sleeping Bag is built for adults who value space, warmth, and easy versatility on camping trips, backpacks, or car journeys. Sized at a generous 75 x 33 inches (190 x 85 cm), it accommodates most sleepers up to around six feet tall, allowing natural movement and spread-ease without feeling restricted.

Inside, a soft, skin-friendly flannel lining wraps you in gentle warmth. The exterior uses a 190T tear-resistant polyester shell that offers dependable water- and wind-resistance, while hollow-fiber fill adds to the overall warmth without unnecessary bulk. The result is a companion that feels comfortable from the first sleep to the last, whether you’re refreshing on a cool night or facing a brisk breeze at dawn.

Smart design for warmth and versatility

Practical details work together to keep you comfortable in varied conditions. A flannel draft tube along the zipper helps minimize drafts, and a Velcro strap keeps the zipper in place to reduce heat loss. If temperatures rise, you can unzip the bottom for a touch of open air at the feet, enhancing comfort on warmer evenings.
