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: Great for snug spaces! - Great little water bottle if you're a little tight on space, since a more flat-ish shape works nicely in a lot of the bags I use. 10oz is a good amount for sipping on or just getting you through a few hours outside before your next fill up, though it'll go quick if you're thirsty! I can't speak to its durability over time, since I haven't had it for very long, though it appears to be all that it's advertised to be! Plastic feels pleasantly firm, the cap doesn't leak (At least mine doesn't), didn't seem to have any lingering flavors after an initial rinse or two, and is a great way to keep an eye on how much I have left to drink! Only thing holding it back for me is that despite the rubberized exterior being a great accent for color and some added cushion, it also makes it a little grippy when trying to slide into bags as well as possibly picking up little bits of dust and debris easily from wherever you set it down. Not a deal breaker for me, but I wouldn't mind seeing another style that's less rubberized!

### ⭐⭐⭐⭐⭐ One tough cookie!
*by D***G on November 23, 2025*

Driving down the road at 55 mph I hear a thump. Looking in my rear view mirror I see something tumbling down the middle of the road behind me. Suddenly I remember setting my flask on top of my car before leaving home. I turn around to retrieve the flask overjoyed to discover that it only suffered a bit of stuffing on the screw cap. This thing really is shatter resistant! Perfect size for those 3 -4 mile walks. Fits nicely in a pocket.
