Iron Flask Flex Straw Lid

This is the essential refresh kit for anyone who has worn out their favorite bottle. You sacrifice the minimalist look of a standard cap for the convenience of a straw and carry loop, but the trade-off is a significantly more functional, leak-proof setup that survives the dishwasher.
