Description of Backcountry.com Dawn Patrol Vacuum Coffee Tumbler:
The double-wall, stainless steel Backcountry.com Dawn Patrol Vacuum Coffee Tumbler keeps hot beverage hot for up to six hours. Maybe you’ll drink that hot liquid; maybe you’ll use it to thaw the frozen lock of a yurt as the sun drops with the temp, who knows? The Dawn Patrol’s lid locks on tight with a vacuum seal that prevents spills as well as it insulates, and its screw-in compartment leaves room for a teabag or sugar. Double-wall stainless steel construction sheaths your beverage in insulation and protection, and the Backcountry.com logo hit shows the love.
Honestly, I love 100% of my Backcountry.com brand products- except this one. I have had it for less than a month and it is already leaking profusely around the edges. I have only used this a handful of times and there are no visible signs pointing to a cause of aleak.
This thing is great. With the lid cranked down, you can chuck it around like a water bottle and not spill or break it. 12 ounces might not be enough for some people to get their morning fix, but I thought it was plenty and it keeps the tumbler small. In my experience, the 6 hour time is a bit optimistic, but then again I was opening and closing it a lot. It still lasted about 4 even with that. The little compartment is great for putting a teabag in once your brew has steeped, the edge doesn't get hot, and it's nice and slim. I carried it in an internal coat pocket for a day of skiing and didn't even notice it. Plus the brushed aluminum is super cool and you get to rep the Goat.
The size, shape, style is all nice, but it just doesn't do the job - keep things hot. I tried pre-heating it once with boiling water - 2 1/2 hours later my coffee was luke-warm. It doesn't make sense that there are 3 little holes in the top of the plastic cap that are plugged by a little rubber stopper (which is easy to lose down the drain). Even with the stopper in you can feel the heat being lost through the plastic cap and through the metal cap on top. Just not a good design.
