The S-shaped stitching pattern allows for slightly less air entry that does not extend side to side for more opportunities for the cold air to enter. Normal envelope sleeping bags include end to end stitching which creates joints where the stitching meets creating greater chances for outside temperatures to penetrate the sleeping bag. The S-shaped stitching pattern limits those possibilities.
