## Description

Stay hydrated the easy way with the Hydro Flask Flex Straw Cap, designed for cold refreshment with the flip of a cap. Whether you’re heading to school, practice, the gym or just relaxing at home, this leakproof, insulated straw lid makes sipping simple. Flip it open to drink, click it shut when you’re done, and enjoy leakproof hydration from your favorite Standard Mouth Hydro Flask bottle. The Flex Straw Cap is built for convenience. It comes with two straws that can be trimmed to the perfect length for your bottle, with a handy trim ruler included for quick measuring. Once adjusted, you’ll have a customized fit that makes every sip effortless. The cap and components separate quickly for thorough washing, and you can toss everything right into the dishwasher or wash by hand.

Review: Good buy! - Very nice! Closes tightly. Easy to take apart and clean. I like that the softer parts are red so that mold can’t hide.
Review: Worth the extra to get the Hydroflask brand! - This accessory straw top is great. So much better than the other brands that "mostly" fit but aren't Hydroflask. It doesn't leak when it's closed, easy to get the straw in, and best of all doesn't have that soft rubber on the flip lid that breaks down so quick and isn't easy to clean. It's worth getting the name brand that was designed for this bottle.
