Not actually 8 oz
Albeit a nice flask, it’s way under 8 oz. I used a measuring cup and lined it up to 8 oz, and even with some spillage during the pour, it still overflowed. In comparison, my 8 oz Stanley flask took the whole 8 oz (no spillage as per wide-mouth design). Still a solid piece, but it’s well under 8 oz. It’s more like 6.
Leaky
I loved this for the first couple of uses that I got out of it. The drink I had it in on my last use though, ended up filling my snowpants pocket because the tread/seal for the cap stopped being able to line up properly and no matter how hard I try to get it to close and seal shut, whatever you have in the flask is going to leak.
A dandy little jug that fills a niche perfectly
I have had this flask for about six months and use it regularly for 3 to 5 mile hikes. It fits nicely in a pocket and carries enough water for short hikes like that. The small opening is perfect for dosing ones head or neck in extremely hot weather. I have only use this for water. I have no opinion on its use for other liquids. This is a small container, making it perfect for short hikes where I want to carry as little as possible. Obviously, on longer hikes, one needs a bigger container. This is a dandy little container that fills a niche that most of us need. I was strongly recommend buying it.
Leaks
It's a nice size, shape, and design, but the threads inside the cap are plastic and don't mate to the threads on the flask correctly, so the flask leaks.
Works great!
I purchased 2 of these. This flask works great, packs nicely. Like other members commented the opening is small but I pour the contents into a cup. The only real negative comment is the glue residue from the removable sticker. It would not come off. After trying cold water, hot soapy water, rubbing alcohol, I gave up and I used Goof-Off which is basically xylene. I quick cleaned that off with hot soapy water. It didn't ruin the surface!
Leaks! Don’t buy this.
Cannot recommend this flask as it leaks terribly. We took it with us on a backpacking trip and luckily we had it in a ziplock, because the contents leaked all over. We bought this for ski season, so glad to find out before our snow gear is soaked in whiskey on the slopes. Unfortunately we are past the return window.
Great little flask
So far so good. I can see how the plastic/metal interface for the threads might be (or become) a problem, but we used this for a weekend backcountry xc ski overnight with no issues. We were able to open and close it with big mittens/gloves on. We didn't measure exactly how much liquid it holds, but it was enough for our needs.
Durable and Stylish Flask
Durable, stylish, leak-proof, well-designed. This flask is an excellent product. Keeps liquid secure in any bag, pocket, or purse. Made really well and is easy to handle.
Right size
On my 2 night trip on a the AT this held just enough most of all no leaks
My favorite flask, with one flaw
Love this flask. The color, finish, shape are all very satisfying. Only complaint is with the rubber piece to keep the cap when open. The material is like. Rubber band, so there’s a good deal of friction when unscrewing the cap, and it would snag in my pocket. I removed the piece, and now the flask is great, though there’s always the risk of losing the cap. Hope they consider a better material in the future.
