This cap has something for everyone. Most wide-mouth bottles are easy to fill and clean, but the standard opening is too big to drink from easily without spilling. Narrow-mouth bottles are great to drink from but you can forget about putting ice cubes in them, let alone cleaning them. And bottle inserts don't really fix a spout that was never meant for daily drinking.

This cap offers the best of both worlds. Drink spill-free through the small spout, sip through the straw, and then clean and fill easily with the large cap.
