The Kula Cloth is a reusable personal hygiene cloth weighing 14 g, with a silver-ion antimicrobial coating on the absorbent side and a waterproof layer on the back so moisture doesn't soak through to whatever it's clipped against. A snap closure folds it shut after use, and a hanging loop lets you clip it to a pack strap to air dry as you walk.
The antimicrobial coating controls odour between washes rather than eliminating the need to wash it — it should still be laundered periodically, ideally at the end of a trip or when access to washing allows.
At 14 g it replaces single-use toilet paper for urination on the trail, cutting down on packed-out waste and repeat purchases; it's aimed at hikers comfortable with a reusable system rather than anyone who prefers disposable options for hygiene.
