Ascent Straw Lid: Our narrow BPA-Free Ascent Straw Lid is leak proof when the nozzle is in the closed position and is dishwasher safe on the top rack; US Patent Pending

Ascent Straw Lid Usage: Because the straw lid is leak-proof when closed, we do not recommend using it for hot or carbonated beverages due to pressure that may build up within your bottle, which could cause spills
