15 oz. Flask, Patented, Flexible, Metal-Free, Reusuable, Plastic, BPA-Free with Carabiner Clip and Filling Funnel

Why didn’t I purchase this product sooner? I go to a lot of Jazz concerts in the park and I just pour my drink of choice into the flask and put it in my backpack cooler. It’s easy to pack and carry and the sealed top stops any kind of spillage. I love it.

I saw another review say these are not good for backpacking, but I had the exact opposite experience.I took all three of these on a 7 day backpacking trip in the High Sierras. We setup base camp at 9,980 elevation just below the tree line, and did day trips up to 11,000 elevation. I had all three flasks filled nearly to the top and stuffed into my backpack and encountered absolutely zero leaks or issues at all.Filled them with Double Chocolate Liqueur, Praline Sipping Cream, and Vanilla Peppermint Baileys to mix with coffee and hot coco. They lasted the entire tirp without a drop leaking anywhere it was not supposed to go. They are super lightweight at half an ounce each, and hold around 18 oz of liquid. Great deal, and I highly recommend these.

This product deserves a "chef's kiss". Perfect for sneaking into festivals. DOES NOT LEAK, even under pressure while being stashed under clothes or belt lines. The plastic clips that are supplied are strong and durable and able to handle clipping onto belts, hanging on the hem line, or clipping around the overall buttons. Best investment ever for festival life, when trying to save some money.

These are about a third of the price of the name brand and they hold a substantial amount. The markings say 15oz but the literature in the package hints to that not being correct, I believe it holds more. The carabiner is useless but that’s not what you’re paying for and the funnel is a very nice add one.

Wife and I often go away for the weekend. We always brought a jug of water with us, but then you either throw it out or have to bring home a bulky container. These things are great, they collapses down to nothing when finished. We have 6 of them. So far they do not leak. Seems sturdy and hopefully will hold up for awhile.

Threw this in my backpack and put stuff on top of it. Tossed my backpack around and no leaks. I like the fact that it hold more than most collapsible water bottles. The only thing thats not great is the measurements on the side are just for looks. Not sure why they even put them there then. But they don’t affect functionality, so oh well, all in all a good collapsible water bottle so far that holds much more water than most it’s height.

Perfect for a sneak in cocktail! Perfect size

I had previously ordered a cheaper version of this type of flask and I thought it did the job. This version was impressive in comparison. It has a quality feel and it's much more comfortable when stashing it in your pants. It also has a Guage that tells you how much you have in it. How would you add your beverage? No worries, they include a perfect funnel. What if you want to Clip it instead of stashing it? They thought of that too! It comes with durable removable clips. This is a must have for liquid consumption on the move.

This is a very basic flexible flask. As others have suggested, I see no point in putting a huge flask label on the item on both sides when its supposed to be discreet. The main problem with this item is that when the flask is open, the locking ring can be easily lost as it is not held into place by anything. If that ring is lost, i think this item would start leaking. Tested with water first and held up fine even when i applied some pressure when fully closed. Item did not leak. The real test will be real world conditions.3 stars due to the locking ring issue.After using it this and washing it, the flask takes FOREVER to dry out. I left it out and open for 2 days and it was still wet inside. Be sure to have a fan to circulate air to dry it out or else it will take forever to dry inside.
