    • Great product
Style: 40 Oz Color: Black
I have been using it daily for over a year. It's leak-proof and keeps ice from melting all day. I have dropped it multiple times without any problems. I love its sleek design and perfect size. Durability is spot on!!

    • Better than the Former Version
Style: 20 Oz Color: Moonshadow
My Hydroflask from 2019 finally gave up the ghost, after I had repeatedly banged it on the bottom. Finally bought a silicone boot, but it was too late for the old bottle. This new one seems better designed, especially near the top. And it's wearing the boot, so it won't get banged up! Works like a charm, keeping ice for as long as 24 hours. ... show more

    • Perfect
Style: 32 Oz Color: Black
I wanted a bottle that was all stainless steel and easy to clean. This one checks all of the boxes. It holds a lot of water and keeps it cool with the lock. I would buy it again in a heartbeat. The handle makes it easy to carry around as well. It's worth the price.

    • Very nice water bottle, but the prices...

Review Image by Casual Reviewer Casual Reviewer
I understand why people like hydro flasks so much, they really are excellent quality. Does not leak. Will not precipitate (or "sweat") even with ice inside. Will stay cold all day. Installation is incredible on this one. However, the prices can get kinda of crazy on some of these. Over a dollar per oz on these things or much more sometimes. While I like the quality, the price gouging on some popular products like these is out of hand. Grey for 24 bucks and dark green for 44 bucks... hmmm, me thinks the quality is not what's being charged for here. Supply and demand, newer colors, I know how it works. But still, business practices like this leave a sour taste in my mouth when they are so obvious. It's a 50% difference. However, I would not discourage people from buying this product. It still outdoes itself in many aspects. I would just recommend waiting for a sale. 😂 ... show more
