Excellant but pricey at $27 but not too happy for $34.
Very nice water bottle! (for $27) it's big brother the wide mouth flex chug was even nicer, I loved both but at $34 and $42 respectively is cra cra. I liked both Hydro Flasks better than the less expensive Hydro Cell product, but that was nice too. it's a water bottle! I'm on the Zep shot, happily losing weight here, but lets us not go crazy....it's a water bottle for kris sake! lolI'll keep the 21oz Hydro Flask Standard for $27. (even that is a tad pricey, and wait for a sale to back up with a second one hopefully the Flex Chug Cap.

Great water bottle for a day out
I have many pieces of Hydro Flask now. They are well made, keep water cold all day, and reasonably priced. I got this one because the opening is large enough for ice cubes and still easy to drink out of without spilling. I have the 21 Oz which fits nicely in my car cup holder. It is sleek looking and the little handle on top is handy.

No weird smell from the bottle while drinking
It keeps my drink at the right temperature really well. I also don’t notice any strange smells when drinking, which is a big plus compared to other products I’ve used before.

Small opening
The opening is a bit small for some ice machines making it difficult to fill with ice. However it keeps drinks cold for the entire day!

Unbreakable, doesn't leak, keeps drinks cold / hot!
Bought this to take on a hiking trip, fit in my fanny pack, kept my water cold, easy to retrieve from the fanny pack, easy to open and close. Unbreakable & Did NOT leak. 10 out of 10 would recommend and will probably buy another one to have a pair to hike with.

Works well
Whether I put hot or cold liquid into this doesn't matter. Either way, the liquid stays at the same temperature for almost 24 hours. The handle makes it easy to carry and by twisting the lid, you can easily open it. It won't come loose by itself. It's also very strong and has survived me dropping it MANY times but there are a few dents from that.
