Hydration just got 10x easier. Whether I'm hiking, driving, or just lounging, this cap makes sipping effortless. The flex straw is soft yet durable, and the seal is rock-solid. No leaks, no spills, just pure convenience. 10/10 recommend.

Great design overall, super handy during morning runs. Only downside? I accidentally left it in the sun too long and the straw got a little warped. Still works, but be careful with heat exposure.

Works okay, but the straw is a bit harder to clean than expected. Gets gunky near the bend if you don’t scrub it right after use. Functionally solid, just needs more TLC than I hoped for.

Love this add-on! Fits my Hydro Flask perfectly and doesn’t leak, even when tossed in my backpack. The flexible straw is so convenient for staying hydrated on the go. Worth every penny.

I didn’t think I needed a straw cap until I tried one. Now I can't imagine going back. It’s leak-proof, easy to clean, and makes drinking from my flask effortless. Even survived a tumble off my bike—impressed!

This straw cap is a game-changer! I used to struggle with chugging water during hikes, but now it's like nature handed me a built-in smoothie machine. Perfect for quick sips without stopping to unscrew anything. My dog even tried to use it—high praise.
