Frequently Asked Questions
Are these Hydro Flask bottles truly leakproof?
The Flex Straw Cap is designed to be leakproof when closed, but customer feedback shows mixed real-world results. Proper assembly and closing of the cap help prevent leaks; if leakproofing is critical, consider a screw-cap or inspect removable gaskets regularly.
Can I put these bottles in the dishwasher?
Most listings note dishwasher-safe components; Hydro Flask recommends disassembling the straw lid before washing. Regular cleaning of straw parts and gaskets prevents buildup and preserves function.
Can I use the straw cap for hot beverages?
No — the Flex Straw Cap is not intended for hot liquids. Use a dedicated insulated coffee cap or a screw-top lid for hot beverages to avoid scalding and to protect lid components.
