HTMEYBG 3-Season Sleeping Bag for Boys and Adults, Lake Blue, 3 lbs, Lightweight Waterproof with Compression Sack

HTMEYBG's 3-season sleeping bag is a roomy, lightweight camping sleep system designed to keep teens and adults comfortable from spring through fall while packing down small for backpacks.

Built to balance warmth, breathability and portability, this sleeping bag uses a waterproof nylon shell, soft polyester pongee lining and hollow microfiber fill to provide insulation without bulk. At 86.6 x 31.5 inches (220 x 80 cm) it fits taller users and can unzip fully into a blanket, while the included compression bag reduces packed volume for trail-ready transport. Comfort and limit temperature ranges make it versatile for everyday outdoor activities like camping, hiking, and travel.

How warm is this sleeping bag for three-season use?

The HTMEYBG sleeping bag is rated with a comfort range of 50°F–68°F (10°C–20°C) and a recommended limit of 41°F–77°F (5°C–25°C), making it suitable for cool nights in spring, summer evenings and mild fall weather. Its hollow microfiber fill traps heat while remaining lightweight, and the breathable shell helps regulate temperature so you won’t overheat.
