    Great Water Bottle

    • Familiarity: I've used it several times

    This thing goes with me everywhere! It fits just the right amount of water for games, concerts, skiing, pretty much anything I do! Buy this if you need a sturdy flask for all your drinks!!

    Super Heavy Duty

    • Familiarity: I've used it once or twice and have initial impressions

    This isn't your average "I bought this at a gag gift store" flask. It's heavy duty (literally, the flask is pretty heavy), super insulated, and I imagine will put up to anything you could put it thru.


    • Familiarity: I've used it several times

    I love the look of this flask, it has great style for those outdoorsy folk that like to sip on some booze as well. And it is made by Stanley which has been an staple brand in the camping industry for a long time now. This isn't a flask that I would take hiking or mountaineering with me though as it is quite heavy, but is extremely sturdy and well made because of that. I use this as more of a car camping/resort skiing flask and love it. Stanley makes some great flasks that are more lightweight and would be more suited for lightweight backpacking. If you are looking for a sturdy flask that you'll keep for years, then this is the one for you. Let me know if you have any questions : )

    So amazing, it needs a Marvel movie

    • Familiarity: I've put it through the wringer

    I am no stranger to Stanley products as my current thermos is by the same brand, passed down two generations. When I had purchased the Master Flask, I wanted a flask that would bounce back from the abuse of all of my outdoor activities, and still be able to hold a celebratory whiskey when the ride, hike, or climb peaked. This monster has exceeded every expectation I could have had. The added weight tends to bode well for this guy, because I accidentally ran over it shortly after purchase. Whoops. But if we are honest, I was not surprised in the slightest when it was completely ok after picking it up off of the ground.

    If you are looking for reliability, durability, or just something cool to gift, this is the flask for you. If you have any questions, please reach out to me at

    Stanley Master Flask - 8oz

      A little heavy, but this thing is bombproof. Love the wide opening for a true pull and easy pouring. No funnel required. The foundry black color and texture is great.

      Good for Weightlifting

        Okay so it's heavy, but I see it as a positive- Get some extra arm curls in while you're camping or at a concert. I particularly like doing goblet squats and taking a shot every third rep. It's bomber and looks steezy.
