Please DO NOT use HOT liquids with HidrateSpark PRO Chug and Straw lids because these lids are NOT designed to withstand the pressure of HOT liquids.
However, if you purchase a FLIP LID from our accessory page, and place on your bottle you then can put both HOT and COLD drinks in it as the FLIP LID is built to withstand the pressure of HOT liquids.
The FLIP LID is compatible with 17, 21 and 32oz PRO bottles.
