Thindown

From TheUltralightHiker.com: Thindown. A new down insulation material. Thindown creates this fabric by adding an adhesive to the down after it has expanded which then traps the down between two ultralight layers of fabric so what it can no longer move around. This means that the resulting product can be used in many different ways to create a range of new down garments and products which do not require channels or quilting. It also makes the down garment much more washable or even dry-cleanable. It is a brilliant idea, and will seriously challenge synthetic insulation.
