TASCO water bottles use the Purist technology developed by Specialized. This treatment to the inside of the bottle shields it from any bad taste, mold, or staining. As pure as drinking from a glass, but with all the advantages of a flexible bottle. No "carry over" from yesterdays drink mix - your bottle stays clean and your water tastes pure - each and every ride!
Lid: MoFlow- easy to open, effortless to use, and leak-proof when closed
