Coleman Big Bay 40°F Cold-Weather Sleeping Bag for Big & Tall Adults — Headrest & Foot Vent

Stay warm and comfortable on cool nights with Coleman Big Bay 40°F

When the temperature drops, a reliable sleeping bag makes all the difference. The Coleman Big Bay 40°F is designed for bigger campers, offering generous space up to 6 ft 5 in, while maintaining a compact footprint for easy packing. The contour shape and built-in headrest work together to provide neck support and soothing warmth, helping you rest more soundly after a day of outdoor adventures. With Coletherm insulation at the core, you’ll experience a steady level of warmth that can help you feel ready for the next excursion without feeling boxed in by your sleeping bag.

Thoughtful features address common camping realities. The Thermolock draft tube wraps around the upper body to help minimize heat loss, while the J-zipper at the footbox gives you adjustable ventilation on warmer nights. When it’s time to pack up, the compressible stuff sack keeps everything organized and easy to carry, whether you’re heading back to the car, to a trailhead, or to a backyard campsite for a stargazing evening.
