Description
Product introduction:
The white duck down filling material is
comfortable and warm, the sleeping bag is very light, and the down is very soft
and light, very warm. The material of the sleeping bag and the unique sewing
process can make it difficult for the outside cold air to reach the inside, and
the inside hot air to reach the outside, so that the temperature can be
maintained. The fabric is waterproof, and it’s OK to get wet in light rain.
Down’s heat preservation principle:
The down is very soft. Although it looks thin,
when you sleep in your sleeping bag, the down will attract your body
temperature, expand the down, isolate the cold air from the outside, and
achieve the effect of keeping warm. It looks thin when the temperature is low.
After attracting your heat, it will become thick when the temperature is high,
which is normal.
Notice for purchase: When you purchase a

sleeping bags, we will send you a left zipper and a right zipper, so that you
