This sleeping bag is made of 100% polyester fiber fabric, which is light and breathable, hard and wear-resistant. It is treated with dense warp and weft threads to make it more wind-resistant, cold-resistant, and warmer. The size is approximately 72.78*29.5 inches, and the U-shaped cover can fit tightly against the head when tightened to prevent cold wind from entering and heat loss. Envelope opening, easy to clean.
