Conducted a temperature test. How long to stay hot?
Full hot water from the faucet. I think our water heater is set at 125°F so maybe conservatively I’ll say that the water temperature started at 115. I set it outside at exactly 9 PM last night. I picked it up at exactly 9 AM this morning. the starting temperature at 9 PM was 44°F and the ending temperature at 9 AM this morning was 32. And when I drink it this morning, I’m gonna say that the water felt like bathwater so probably 80° (I go swimming at the YMCA a lot, so I feel confident that it was 80°F) So that’s a temperature drop of 35° in the water over a 12 hour period where the average temperature was 38°F outside. So I’d say that the thermos has some thermal insulation properties probably would be good on a short hike in some freezing temperatures. So I plan on keeping this thermos for some shorter hikes that may not be quite as cold, but for hikes longer than three hours in temperatures approaching 0°F, a double capped thermos I’m going to estimate will be a better choice.other notables: Leakproof. I also got this thermos specifically for its size. I wanted something that maintained the same cross-section throughout its entire height. I did not want narrow at the bottom and wider at the top. and I wanted something that was no bigger than 3 inches in diameter, so that it fit perfectly in the side pocket of my bag shown in the picture. I got the 21 ounce version so that it’s not too tall that it would possibly fall out of the side pocket of my bag. and I can put the side strap of the backpack through the loop of the cap for extra security that it won’t fall out. Also, there’s another lady at my workplace that had this exact same thermos and she is an avid hiker and has used it for many years and it’s her favorite thermos.

Always stays cold
I have bought other brands of water bottles and this is the only one that keeps my water very cold all day. I live in the south and I would leave this in the car when it is over 100 degrees and when I come back hours later, it is still cold. Well worth the money. I’ve had mine for 5 years and it is still like brand new!!!!
