Weird Smell

When I opened the bottle up it immediately wreaked of what smelled like cinnamon gum. There were rust like spots right inside the top of the bottle as well as on the part that screws into the lid.

Love the bottle, hate the cap

When are the regular caps coming back? I hate the caps with straws.

I absolutely love my hydro

I absolutely love my hydro flask. I love all the stickers ive decorated with and even the dents and scratches its had. It just lets my appreciate all the amazing memories ive made staying hydrated with my favorite water bottle. what i love more though is the hydroflask company. they just devote so much to their amazing values and I feel so great supporting this brand.

LOVE my Hydro Flask

I love this water bottle. It keeps ice overnight and is so easy to maintain! Keeps me going all day and helps me keep up the right amount of water intake.

Hydroflask with straw

Good bottle but definitely needs to be cleaned often and does leak occasionally

Great bottle

This summer I’ve really appreciated the ability of this bottle to keep my water cool in hot weather. The straw cap is easy to take apart and wash.

Good Water Bottle

I keep upping the size of my Hydroflasks as the hot weather makes more and more water necessary for my daily walks. The 40 oz just about does it and I was able to use the sling from my 32 oz. , still not too heavy to carry around. I prefer Hydroflask to Yeti - the Yeti I bought just didn't keep the water cold long enough. I would not say the Hydroflask is exceptional either on that score, but I think it does a better job.

Love!

The best double wall insulated water bottles. Doesn't leak and I am comforted knowing that these are lead free!
