Fengzel Outdoor Newest 3D Quilt Sleeping Bag for Envelope Legs High Quality Feather Suitable for 3 Minimum Operating Temperature Outdoor Down Shruff

[Envelope shape for a relaxing sleep] This is a 220*130cm envelope-shaped sleeping bag for two people, with the top and bottom sides of the sleeping bag made of the same width, and zippers on the sides and feet. You can easily move your limbs inside the sleeping bag, bend your knees, and turn over. When fully opened, you can enjoy the relaxing comfort of sleeping on a warm futon. [Down rate 93% high-quality down filling] We use high-quality feathers obtained from the chests and bellies of waterfowl that are carefully raised in down production areas with large temperature differences.We perform a careful feather cleaning process such as dust removal, washing, drying, and cooling to create a 93% high-quality down that is intertwined with large down balls from which many ultra-fine barbs radiate. It can contain a lot of air and achieve high heat retention. Also, it is light and soft to the touch, and has excellent comfort, elasticity, and bulk. [Multi-Performance Fabric] The front and back of the sleeping bag are made of 400T nylon and polyester with a strong water-repellent finish, which not only prevents the down from blowing out, but also prevents the down from getting wet from the moisture of the outer layer. It locks in the warmth of the feathers and has good heat retention. In addition, the fabric's inherent beautiful luster, good breathability, lightness, softness, and gentle feel are also appealing, allowing you to enjoy a light and comfortable feel that is compatible with your skin. [Three-dimensional box quilt structure] We use a quilt sewing specification that creates a three-dimensional box structure between the front and back sides of the sleeping bag, and the down in each square traps a three-dimensional air layer to prevent cold air from entering and maximize heat retention performance! The box structure gives it height, so the feathers have excellent bulk. In addition, this will prevent the down balloons from moving and shifting in each square. It also has the benefits of being easy to fit your body, convenient to wash, and compact storage. [Put your legs out] Comes with a zipper with a puller that allows you to freely open and close your legs, so you can open the zipper and sleep comfortably on hot nights when it's hard to sleep. In the cold season, you can close the zipper and wrap your whole body for warmth. It is very convenient to be able to ventilate and adjust the temperature depending on the camping location, temperature, season, etc.
