Rated 5 out of 5 by from LOVE IT!!! I love my new Purist bottle!! I have used it on my last few runs & it's the best bottle ever!! I got one a few months ago and didn't like the then 'new' cap. I wrote a review that the original top was better & wish they hadn't changed. I immediately got a response from Brian Frank that they were not happy with it either and he sent me a replacement top that I preferred. Awesome customer service. Now this latest Fixy cap is even better! When I go on long runs, I do loops from my house to change out water bottles. I love this one so much I just kept filling it from the line up of other bottles prepared! I guess I need to get some more Purist bottles! Thank you Brian & Hammer Nutrition!!

Rated 4 out of 5 by from Great water bottle no leaks and colors stay intact I've got 4 of these and they work great. However, I'd remind folks to take the nozzle off and throughly clean out the valve parts as they can get some pretty nasty build up even when you think you've cleaned the bottle sufficiently.

Rated 5 out of 5 by from Must-have bottle! The lid and logo are very durable, and clean easily. I've used it nearly every day for four years. Superb design.

Rated 4 out of 5 by from Good quality Love the quality of the plastic, design and flex, but I really don't like the spout which only open by pressing the bottle, then boom a ± big blow of water if you pressed too much. Took them all off to replaced with old lid from bottle I was recycling because of bad smell. Will not buy again because of lid.

Rated 5 out of 5 by from Another great product from Hammer I purchased four bottles a few weeks a go and was very impressed with the quality of the bottles. I had no leaky lid issues and I like the amount of liquid that was delivered when I needed a drink. Thanks Hammer for another outstanding product.

Rated 5 out of 5 by from Slightly New Design The bottle and spout are a little smaller than earlier models. It's taking a little time adjusting to a smaller spout. Nonetheless, good product.

Rated 4 out of 5 by from Excellent product fluids stay cold and easy access Am a marathoner/triathlete and been using hammer gel since the midto early 90's my love for it is that it's very easy going down and digestible.

Rated 5 out of 5 by from Best bottle I have ever used! Best part of the bottle is the valve, doesn't spill when left open. Only gripe is it's not available in other colors. Already bought two more.
