Love it.
After I lost a generic souvenir bottle my mom got me at school, which I wish I could find out the name of so I can rant about it because it would spill no matter how much you tipped it, which resulted in multiple large spills in the few weeks I used it, I ordered this because I knew the brand had a reputation for quality and the size was exactly what I needed, and it did not disappoint. It fits perfectly in the pocket of a bag and it hasn't leaked once. Very easy to open, although it felt a bit tight when I first got it, the color looks great, and, while it's a bit expensive, I think you still get your money's worth from this bottle.

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.

Excellant but pricey at $27 but not too happy for $34.
Edited: Very nice water bottle! (for $27). Hydro Flask bottles are beautiful, minimalist design but it's a little hard to swallow, even more so with its big brother the “wide mouth flex chug”. I loved both but up to $34 and $42 respectively is cra cra. The hands down winner is the Farsea brand 24 oz with paracord handle, integrated cap handle and removable silicone. I picked up the beautiful Farsea with dual caps for $22 it's a water bottle! I'm on the Zep shot, happily losing weight here, but lets us not go too crazy....it's a water bottle. I picked up a nice Wontego paracord shoulder strap as a nice addition that none of them include for $11 so maybe I went a little crazy, but I’m happy with end product. :)
