Customer Reviews
Mr. L***********ann I
I bought two and immediately wanted more. My kids stole one for school, and now my husband uses the other for work. Keeps coffee hot through winter mornings and water icy in summer. The Flex Sip cap is genius—no more chugging like a caveman. Best hydration upgrade ever.

Works well, but took some getting used to the flip mechanism. Not as intuitive as I hoped at first. Once you figure it out, it's solid. Lid feels a bit flimsy compared to the sturdy body.
Magda********** DVM
I’ve had this for months now and zero issues. Dropped it on rocky trails and it still looks brand new. Sip function works smoothly, and I appreciate that it’s dishwasher safe (top rack only!). Highly recommend for hikers and busy parents alike.

Perfect for my morning gym runs. The wide mouth is great for ice cubes, and the sip lid doesn’t leak—one fewer disaster in my car.

Solid bottle, great insulation. Only reason I’m not giving 5 stars is the cap gets tricky to clean around the hinge. Still, my go-to for camping trips.

This Hydro Flask sip cap is a game-changer! No more spills in my backpack during hikes. I love how easy it is to drink from—just flip and sip. Keeps my water cold all day, even under the hot Arizona sun. Worth every penny for outdoor adventures.
