BOT 2.0 - the next generation of the original BOT weighted straw sippy cup. This straw sippy cup uses the same Siliflex weighted straw but now comes with two ways to sip 1) direct connect straw with the original weighted straw or 2) Disc + weighted straw. Disc + straw option creates the patented buffer chamber to equalize pressure in the cup so you can enjoy your favorite warm liquid. Whichever way you choose, both options use the weighted straw so you can still sip to the last drop.
