The Ion8 is a revolutionary new sports water bottle. 100% leak proof, the Ion8 is designed for rapid hydration. Regular rigid water bottles are painfully slow to drink from; soft bottles can be squeezed, but often leak. Ion8 is rigid, crystal clear and has a vented, smooth liquid flow. No glugging, no squeezing - just effortless hydration! Concave sides for a comfortable, slip free grip. Open with one hand and easily lock closed for peace of mind. The pouring spout is under a hard shell, keeping it clean, fresh and hygienic. No dirt, no wiping. Made with the finest odor-resistant BPA free, Phthalate free, non-toxic Tritan. Get supercharged!
