GSi Outdoors Boulder Flask Thermos,Unisex Adult, Unisex_Adult

The GSI Outdoors Boulder Flask Thermos is a fantastic companion for outdoor enthusiasts and travelers looking to enjoy their favorite beverages on the go. This flask has quickly become my go-to choice for its style, reliability, and impressive thermal performance.First and foremost, the design of the Boulder Flask is sleek and eye-catching. The durable stainless steel construction not only looks great but also ensures long-lasting durability. The textured grip adds a touch of elegance and provides a secure hold, preventing any accidental slips.When it comes to thermal performance, this flask truly shines. The double-wall vacuum insulation keeps my beverages hot or cold for extended periods. Whether I'm sipping on a steaming cup of coffee during a chilly hike or enjoying a refreshing cold drink on a hot summer day, the Boulder Flask consistently delivers on its promise.Another feature that sets this flask apart is its convenient size. With a generous 10-ounce capacity, it strikes the perfect balance between portability and capacity. It easily fits into my backpack or bag without taking up too much space, making it ideal for outdoor adventures or daily commutes.The leak-proof cap ensures worry-free transportation, preventing any spills or leaks. I appreciate the thoughtful design that allows for easy pouring and drinking, thanks to the well-designed spout and integrated cap.

This container holds liquids, and when I screw the top on, they don't leak out. The bottle seems pretty durable, too, which is a plus.I will note, this is bigger than I expected. You can't fit this flask into the average pocket. It certainly won't fit in and pants pocket, and likely won't fit in most jacket pockets either. That's on me; they obviously can't make it smaller while still holding the same volume. But it's a good thing to be aware of.

Awesome flask! Seems durable and holds enough to get pretty darn tipsy. Lid seals tight. Pulling it out, unscrewing the lid, flipping the lid back and forth, and screwing the lid back on can be done one handed.

Really good volume, 10 oz is nice.The cap must be screwed on tightly or it will leak.Pours well and can be sipped from comfortably.Grippy sides so a little difficult to slide into and out of pockets but over all a solid and enjoyable flask.

I haven't exactly done any impact tests, and the rubber border doesn't feel like it's sturdily attached, but for some reason it feels solid. The rubber thing is more like a sleeve for the actual bottle. Could be inconvenient getting out of a pocket cuz the rubber grips, but alternately it won't fall out of a pocket nearly as easily. So whatever your needs are. I use it as an alcohol flask.

These are excellent. Won't set off a metal detector, and won't leak. I found that if I left bourbon in a metal flask for a few weeks, the bourbon got dark. I thought I was getting a little metallic flavor too, but that might just be from the darkened whiskey. Anyway, those days are over now. Bonus is that you can see what's in there, how much is left, and how much you are pouring.

I bought this to not set off metal detectors and bring some whiskey into Broadway shows where drinks are like $25. It worked but now I mostly just use it camping.

I used to put my backpacking bourbon in water bottles. It saves weight.. but they eventually leak. Better to not have no bourbon and bourbon soaked gear and to have a non leaking flask. I like that the lid is attached so does not get lost. I like the larger opening than a normal flask. Makes it easier and faster to clean.
