Review: Great flask!! - This is the best plastic flask I have bought. Highly recommend for the use and the durability. No leak, easy to unscrew the top and easy fill. Fits perfectly in a jacket pocket and not detectable with metal detectors (wink,wink).
Review: Very Nice and Looks Great - Love the look and feel of this flask. Only concern is that it maybe hard to clean - however, it shouldn't be a problem if you just keep liquor in it and not a sugary mix.

- Wide mouth opening makes for easy filling, pouring and drinking; Molded graduation marks help you quickly measure or see what’s left while you’re on the trail
- See-through design for a fun and novel drinking experience; Hinged top with grippy silicone bumper makes for easier opening, helps prevent leaks and ensures you won’t lose the cap

### ⭐⭐⭐⭐⭐ Great flask!!
*by K***T on September 6, 2025*

This is the best plastic flask I have bought. Highly recommend for the use and the durability. No leak, easy to unscrew the top and easy fill. Fits perfectly in a jacket pocket and not detectable with metal detectors (wink,wink).

### ⭐⭐⭐⭐⭐ Very Nice and Looks Great
*by D***S on May 8, 2026*

Love the look and feel of this flask. Only concern is that it maybe hard to clean - however, it shouldn't be a problem if you just keep liquor in it and not a sugary mix.

### ⭐⭐⭐⭐⭐ Water, water, everywhere…
*by U***P on June 20, 2021*

I got this to carry water with me in a small daypack or sling bag along with other daily essentials. While the flat design makes it very easy to pack in either bag, the rubber bumper that goes around the outside grabs on to my backpack when I’m trying to push the bottle down one of side pouches. It isn’t a big deal, but worth noting. It slips in and out of my sling bags with ease, and the size is just right for my purposes. The cap screws down securely and the bottle does not leak, it is clearly built quite tough, and being able to see through the smoke side makes it really easy to keep tabs on remaining water. One nice thing is that it doesn’t look too much like a hip flask, so drinking from it in public doesn’t feel weird, and it just looks like you’re drinking from a small water bottle. So far I’ve been very happy with it and would recommend it hands down.
