The "sleeping bag quilted pants" I made in the winter of 2023-24 were very useful and I wore them a lot, but at that time I thought, "It would be light and useful if I also had a top," so this winter I tried making a shirt. The ultra-thin nylon fabric with a crinkled surface and quilted padding makes it both light and warm. I made it with a moderately loose silhouette so that it can be worn like an outerwear.
