The Contender Topo Purist MoFlo 22oz Bottle is another collab with Specialized, but this time with a fresh topo design that stands out. Just like the Striped version, it features an amorphous silicon dioxide coating that gives it a smooth, glass-like finish inside. This coating keeps your drink tasting fresh and clean, preventing any weird aftertastes or stains-even on those hot days when you need it most. Purist infusion: Prevents odors, stains, and mold, so your water stays pure and the bottle stays fresh. Large screw-top design: Leak-proof and wide enough to add ice or mix in powdered drinks easily. Updated MoFlo cap: Delivers a smooth flow, with an improved grip and flush top for better cleaning. Totally leak-free when closed. Easy-squeeze LDPE material: Flexible design for quick and easy hydration. Clear viewing strip: Lets you keep an eye on how much water you&&';;ve got left. BPA-free plastic: Made with FDA-approved, food-grade materials and printed with non-solvent based (UV cured) ink.
