Breathable 1.1 oz ripstop polyester with DWR. Lightweight, but still fairly durable fabric. Specifically finished to have a softer hand feel.
This fabric can be purchased in a downproof calendered version, or an uncalendered, more breathable version. Great for projects such as top quilts, under quilts, sleeping bags, pillows, jackets, garment lining material, and lightweight stuff sacks/bags.
