NathanRunning Handheld Water Bottle Adjustable No-Grip. Quick Squeeze Lite Hand Strap. 12oz / 18oz / Insulated. Reflective Hydration Water Bottle.

I like it! Fits well, easy to drink from, doesn’t leak at all. It was about 55-60 degrees out on my two runs that I went on and my hand got super sweaty. The hotter it gets the worse that will be, but I think any bottle you hold is going to have that problem. Doesn’t slide off my hand or move around. So all in all, I find it does it’s job well and I would recommend it.

Good running bottle in terms of size, shape and comfort. I vehemently dislike the size and function of the mouthpiece. It feels cartoonishly large, hard to quickly seal around and leeks if you don't. For all the good this bottle has, it will likely go into the drawer because it's primary function of delivering water annoys me so much. I would not buy again nor recommend.

I like the bottle it's simple easy to carry comfortable enough you can carry it a couple different ways. If it's hot the water does get warm weather quickly but that's okay. I I feel it's quite expensive for what it is. The value is not quite there.

Love this bottle. I live in miami and it’s super hot and humid so practically impossible to run without hydrating. I fill this with electrolytes ice and water and it gets me through long runs. Barely feel it’s there

I keep buying handhelds. I must have 8 or 9 of them now. Which doesn't make sense because I've only got two hands and I don't even go through a whole bottle when I run. My favorites are the old school bike bottle ones that were just a strap, no ergonomics or bite valve technology, or not leaking all over your hand for 15 miles.This is a huge upgrade from those old things. Ergonomic, lightweight, dry. All the things you want from a water container held in your hand when jogging across the landscape.As previously stated, I've got lots of these dang bottles with straps attached; but I needed a new, very specific one. I needed something just for training runs. Something without pockets, or zippers, or plastic windows for phones, or any other flashy junk. I just needed some water in a bottle with a strap. I also didn't want a soft flask because those are a PITA to set down.This hits all the markers for what I want and it does it well. It's got a different bite valve than I am used to, so I had to learn how to use that; and since I got the 18oz bottle, it gets a little off balance when it's about 1/3 full. These are all things that I'm used to and don't really bother me at all.Overall this is way better than my old system of an old sports drink bottle and some athletic tape. FIVE STARS!

Omg, this is the worst designed product I've ever seen in my life. Before companies started making handheld water bottles for runners, we would use Aunt Jemima syrup containers filled with water. The hard plastic handle could slide on your hand and stay there without having to hold it tightly. Yes, that cold hard plastic is a way better design for running than this actual water bottle that was supposedly made for runners.Rundown:* The nozzle will not stay open after you open it, so you can't ever get any water out.* When you do try to pull it open with your teeth and hold it there, you either squeeze absurdly hard before anything will start to come out or suck insanely hard before anything will come out.* Because you must apply so much pressure, it squirts every where all over you mostly on the ground, barely any in your mouth -- this is extra bad if you use a mix like Tailwind since you are now sticky every where and wasting an expensive drink and not hydrating or replenishing.* If you ignore the fact that you can't get any water out or in your mouth, it still is terrible because the way it sits in your hand is so awkward and weird. The balance is totally wrong. I've ran with like 12 different kinds and brands of water bottle and never felt so awkward trying to carry something.I've tried 2 of these and they both are the same way so it isn't a manufacturer defect. It is a design defect. DO NOT BUY!! Worst product ever. Worse than the Cornballer. How in the world anyone gave this even 2 stars let alone 5 is beyond me. Did you even try to use it? What possible redeeming quality could you have possibly found in this thing?

The water bottle feels great and is easy to run with. Design and fit is great, and feels like it could have lasted. I wish it could have worked! The problem is that the bottle leaks everyone when you run, so it is not functional. All the water was gone within a few miles of the run from spilling on me and the ground.

Light and easy to hold. Used to train with for the nyc marathon, absolutely would recommend.
