Could Be Better
I bought two of these slings for my children to carry to school. I also bought two of the boots to go with the slings so the bottles could be extra protected. Needless to say the bottles with the boot do not fit in the sling because it was to tight. It would be nice if the sling could be a little bigger so the bottle with the boot could fit. Other than that it is a thing to have so you can have your hands free to do other things.

Nice sleeve or shoulder sling
Overall this product is well made and stays nicely.

That being said there a few things I wish was changed. There is a really small pocket that I can put a key in or water purifier tablet. In either case if was hiking I would not use the sling I would use my day pack and the casual user wouldn't put a key there because I would clip my keys to the loop at the bottom of the sling.

A detachable strap would be a nice option if wanted to have a strapless sleeve. For now I just tuck it inside works well enough.

I'm so happy with this sling!
I am so freaking glad I got this sling for my new HydroFlask. I need a sling to carry it around because my new 40oz is too big for my car's cupholder and having a sling just makes it easier to carry the thing around. First of all it's a GORGEOUS color! Red happens to be a favorite color of mine and this is a beautiful shade of red. I also love how stiff the sling is in terms of protecting the bottle itself. Plus the strap is super easy to adjust and fits comfortably on my shoulder. I have only one nitpick, and that is the useless pocket. I appreciate the idea of a pocket on the sling, but this pocket is basically useless. I genuinely cannot think of anything I can or will be able to store in there. The pocket is too small and too flat to store anything but business cards, maybe. The HydroFlask sling is not the only one to make a useless pocket so it's not just y'all. I just wish you would either make a bigger pocket or leave it out entirely.

Other than that I am super happy with the sling and am glad I bought it to safeguard my new water bottle :

I use this everyday
I love this sling! My hydro flask lives in this sling for protection against scratches and convenience. It is really nice not to have to carry my hydro flask anymore. I saw some reviews that the strap is uncomfortable but I have not had this problem.

Awesome little carrier!
I love it! We purchased it for our trip to Alaska as we knew we would be carrying our water bottle everywhere. We do not have a hydroflask, but the one we have for like a glove. I definitely recommend if you do a lot of hiking or outdoor activities.

Actual color is different than pictured color
I was so excited for this to come in. Unfortunately when it did, the color of the product was most definitely not the color advertised. The pictured color Hydro Flask advertises is a dark khaki gold color with the bottom portion darker than top, the but the sling I got in the mail is a bright yellow mustard color from top to bottom. The bottom of the sling case is NOT darker than the top. It is one solid bright yellow color. The colors look nothing alike and so naturally I wanted to get a different color sling. I contacted customer service to see about an exchange and they informed me they do not do exchanges. They would not pay for return shipping or reimburse for shipping the product you want to return back to them. I am just really disappointed because the product does not fit the picture whatsoever yet they will not make it right by sending me a different one or even reimbursing my shipping cost.

Keeps my drinks even colder
I have wanted one of these for awhile but kept putting it off. When I saw they were on sale I had no excuse. I am so happy with it! Keeps my hands free and the extra insulation keeps my drink colder longer.

Great but stitching is awful!
I’ve been using my sling for about a month and while I love how practice it is, the stitching along the strap is a real problem. The thread is made from some synthetic material and it snags every shirt I wear it with! After a day of hiking the shoulder of my jacket and tank top looked horrible where the strap was rubbing against them. There doesn’t seem to be a way to cut the part that’s causing the snag so I’ll have to think of some way to cover the strap.

Not safe
The idea to neat. I bought one to carry my 32os bottle that is a little to heavy to carry by the finger loop.

However, there needs to be a way to release the strap in case of emergency. It wouldn't be impossible for hydro flask to make one of the plastic buckles into a plastic or metal clip.
