Roomy and Fully Featured Comfort

Enjoy plenty of space with a 72” shoulder room and a 52” vaulted footbox. The two-way, anti-snag zippers let you adjust the bag to your liking, providing easy in-and-out access. Customize your comfort with Pillow Barn, which keeps your dog's pillow secure throughout the night.

Temperature Regulation and Warmth

Stay warm without losing body heat. Our fitted jacket-style hood and internal cinch control ensure your body is snugly wrapped. The “No-draft” collar, wedge, and zipper baffles help block cold drafts, keeping you cozy without overheating. The design reduces air pockets, ensuring your body stays warm and close to your mattress.

Durable and Packable

Crafted from a lightweight Rip-Stop nylon shell with water and stain-resistant treatment and a soft, quiet Polyester lining, this bag is both durable and comfortable. Insulated with FireLine ECO Synthetics—made from 100% post-consumer recycled polyester—it provides excellent warmth. Weighing only 3 lb. 10 oz., it packs down to a compact 8 x 10.5 inches, making it easy to carry.
