The Patizon Stuff Sack is an ultralight organizer bag made from recycled Pertex Quantum nylon with DWR treatment, cut directly from the fabric offcuts left over from sewing Patizon sleeping bags — recycling built into the production line rather than a marketing label. That keeps the carbon footprint sensibly low while retaining the properties of the fabric used on the brand's premium bags: low weight and moisture resistance.
The sack comes in three sizes (S/M/L) weighing 8 to 15 g and in five colours, closed with a simple drawstring. It's not a waterproof roll-top dry bag but a light compression/organizing sack — suited to sorting clothing, layers, or small gear inside a pack, not to carrying items exposed to rain without further protection.
For ultralight hikers, the main appeal is the weight-to-volume ratio: even the largest L size weighs only around 15 g, so building a system of several sacks to organize a pack costs almost nothing in total carried weight.
