GSI Outdoors Flask - 18fl. oz.

My wife and I just got back from a couple nights out on the beautiful Florida trail. It was great having this along with us to have a little something to nip on after dinner while getting cozy around the fire. We actually have the 10 oz size instead of the larger 18 oz size sold here. The 10 oz size is perfect for the two of us, but since the weight difference between the two of them is really negligible, if you have room in your pack I heartily suggest going with the larger one. As others have noted, this container imparts no extra taste to the contents. It seals up very well, is much lighter than a traditional stainless flask, and the wider mouth makes it much easier to fill (and to empty!)

If you enjoy whiskey, but might also like something sweeter, there is a great product that my wife and I enjoy very much. It is called American Honey. It is almost TOO good. It's a great drink to warm you (and your significant other) up on a cool night around the camp fire. It is a requirement whenever my wife and I hit the trail.

Enough for the entire crew. Sturdy and takes freezes well. This thing is big. Look at the photos I uploaded.

Most people have commented on the size and it is definitely bigger than the pictures make it out to be. A standard flask is about 8 oz, so this thing is more than double that size. That said, if you plan on taking more alcohol, 18 oz will do some pretty good damage among a few guys. This this will hold nearly 3/4 of a fifth of booze. I usually just bring this along when there's multiple people and we're staying a couple days. Otherwise, the standard 8 oz flask comes with me.

It appears to be a nice functional design but mine leaked in my pack. I discovered the O-gasket seal in the cap moves out of position when tightened. I thought it was an isolated case but when the second flask did the same thing, I replaced it with a 16oz Nalgene HDPE narrow mouth screw top bottle & the problem went away.

Like others said already it's surprisingly big, but that just gives you the option to part fill or completely fill to manage the weight. The size is no problem if it's in my pack. Certainly not a flask to carry in a pocket. It's cheap, doesn't leak and there is no odor from the plastic. From there the flask can be judged by the quality of what you put in it.

It's a really nice flask to have. Great item to buy if your trying to just get enough for free shipping like me.

Took this guy camping a few times so far and have been pretty well impressed at how it's held up. Be advised; it's MUCH taller than the photo on here makes it out to be. Surprisingly taller to be honest. Holds a LOT of liquor. It cleans very well, (I agree with the below reviewer with the fact that the body of the flask doesn't hold a lot of odor, however the cap has a tendency to do so. I believe this might be because of the small gasket.) Speaking of that gasket, I would have rated this more stars than I did, but that little malleable gasket in the cap has separated and come loose. I expected that this would happen over time but was surprised at how quickly it came loose after two instances of "field" use.

Overall, while it does fill the bill and is useful, I'm thinking about trying another flask from a different manufacturer and moving this into more of a backup role for my camping kit.

Leakproof screw on top,durable and thin profile... and cheap! These don't hold odor at all really- They would if you left some booze in there for a month after your camping trip, but it's really nothing to worry about. I dropped a full one about 10 feet onto hard granite-- just a scratch. They are a little taller then the product photo would indicate- About 8" tall I'd guess w/o having it in front of me.
