text: Semi-feather and semi-cotton sleeping bags are more suitable for use in extreme cold, not a simple mixture of cotton and down, but half of the cover is feather and half of the cover is cotton, because a pressure on the body of the feather quilt will be very thin and not conducive to warmth, as the saying goes, the cover is not as warm as the pavement, so half-cotton and semi-feather sleeping bags are better solutions.
