GSI Outdoors Infinity Stacking Cup

The GSI Outdoors Infinity Stacking Cup features clean & green, non-leaching 100% recyclable clear polypropylene in a lightweight stacking design for compact carry and storage. Infinity is an ultra-lightweight, completely recyclable, BPA-free alternative to polycarbonate resins. With exceptional clarity, jewel-like brilliance and 25% weight savings over polycarbonate, Infinity will not absorb food odors like other plastics and will not leach plasticizers or other chemicals into either food or beverage. Infinity pieces remain strong in both hot and cold and are so light that they actually remain buoyant when filled with water. It's even dishwasher safe and actually becomes more stain-resistant with every wash.Use: BackpackingWt. 1.8 oz. Capasity: 14.2 fl oz.Size: 5.2"x4"x3.3".Material: Infinity clear polypropylene
