A cup that folds down into a disc the size of a palm. The rings telescope into one another and lock flat, so it rides in a pocket, a purse or the front pouch of a backpack and takes up almost nothing until you need it.
It is made of food-grade stainless steel - it will not shatter if it lands on a rock, and it rinses clean in seconds. A buckle and key ring are fitted so it can clip to a belt loop, a bag strap or a jacket zip on the way to a trailhead, a campsite or a concert queue.
Three capacities: 75 ml, 140 ml or 240 ml
Telescopic rings, collapses flat for storage
Food-grade stainless steel, easy to clean
Buckle and key ring for clip-on carrying
One cup per pack. Pull it open to full height before filling.
