Cozy, Built for Cold-Weather Camping

Meet the HiZYNICE Sleeping Bag for Adults, a generously sized 90 by 39 inch model finished in navy blue. Inside, a 100% cotton flannel lining offers a soft, comforting touch, making chilly nights feel a bit more like a warm retreat. The design prioritizes roominess for side sleepers or anyone who prefers a little extra space without sacrificing warmth.

Soft, Breathable Comfort

Soft cotton flannel lining provides a gentle, skin-friendly surface that feels inviting as you settle in. The anti-snag zippers are designed for smooth operation, and they can unzip from the inside or outside, and from the top or bottom, giving you flexible options for ventilation and easy access in tents or cabins.

• 100% cotton flannel lining adds a soft, cozy feel
• Anti-snag zippers unzip from multiple directions for easy access

Adaptive Warmth for Varied Conditions

Three distinct temperature cues help you gauge warmth across different nights and activities, with a heat-retaining draft tube along the zipper to minimize heat loss. This setup supports comfortable use in a range of outdoor scenarios.

• Extreme temperature 20 ℉
• Limit temperature 35 ℉
• Comfort temperature 50 ℉
• Draft tube along the zipper helps keep warmth in

Size, Fit, and Versatility

The bag’s big and tall profile measures 90 x 39 inches, making it suitable for campers up to 6 ft 7 in and ideal for side sleepers who crave extra room. A practical bonus is the ability to zip two bags together for a double sleeping bag or fully open the bag to use as a mat.

• 90 x 39 inches; accommodates tall campers
• Left/right zipper compatibility allows two bags to form a double
• Can fully open to become a camping mat

Care, Maintenance, and Longevity

Maintenance is straightforward: machine wash cold on a gentle cycle. For best shell protection, turn the flannel surface toward the washing machine to shield the waterproof coating of the outer shell.

Practical Use Scenarios

Well suited for three-season camping, cabin trips, car camping and outdoor events where warmth and space matter but portability remains important. The generous dimensions offer comfort without demanding heavy packing.
