Review: AWESOME accessory to enhance my runs and keep me hydrated !! - When I first got into running long distance a few years ago I tried so many iterations of bottles - this by far is my favorite! It’s a solid design, holds just the right amount of water for me and fits in my run vest so I can be hands free, plus it doesn’t break the bank. I’ve also weirdly enough put warmer water in it for winter running! They last a long time - the spout makes the water easy to access and if I don’t bring my vest it’s light and hand sized, making it easy to carry. All in all great functionality. Also their customer service is super friendly and knowledgeable! Rare to have a person on the line AND one who’s friendly.
Review: Easy to use soft flask for running! - This handheld soft flask is great and easy to carry with me on my runs. Easy to use. Has a slight plastic taste at first but I’ve soaked it in hot soapy water and that has helped. The little pocket on the hand held “carrier” works well to hold my keys and a small snack. Wished I’d found it sooner! Good quality. Easy to use and carry!

To hydrate, simply softly bite the mouthpiece and press the soft flask and enjoy! The harder you press, the faster the liquid will exit.

### ⭐⭐⭐⭐ So far this is a love/hate thing
*by W***Y on May 29, 2024*

Update on this, the seller reached out and was very interested in what was going on, great customer support for that. The reason for the 4 stars is because this still feels loose in my hand. When the bottle goes down, i still flip it around and have to hand grip it. No matter what I try. Here's where Im at with this. I LOVE the idea of the smaller water bottle in your hand and not carrying some oversized jug. However..... * When the bottle gets low, you have to switch it from above your hand to inside, if not you wont be able to get the rest of the water out. * The wrist strap should be able to tie closer to your hand. Its very loose when again the water bottle is not full. I find it slipping and have to keep my hand clenched so it wont slip off. * The drinking method does take a minute to get use to, its not just sucking water. You have to bite and pinch the end to get the water to come out. Overall its a much better mouse trap thats for sure. But there are some things that could be refined for sure.
