REI Flip-Top Vacuum Tumbler - 15 fl. oz - Specification

• Durable
  - it is well-constructed, easy to use, good-looking
• Maintains Temperature
  - it keeps everything hot for hours (the drink was still hot 7-8 hours later)
  - I put in ice cubes, left it overnight (about 10 hours), and 80% of the ice was still there
• Compact
  - the part I like the best is being able to drink right from it and not needing to place the liquid in a cup and then drink from that
  - if you overfill the container and then put the lid on, you'll need a new shirt. The liquid creeps into the lid and will drip endlessly, but it isn't inherently easy to tell when you have overfilled it
  - you will love the fact that this thermos doesn't leak
  - feels great in the hand, and can easily be used with one hand provided your hands are big enough
• Lightweight
  - this is very lightweight comparing with other vacuum botles
• Easy to clean
  - not difficult to clean, but not easy
• Stable
  - don't forget to click the button to close the flow of fluid

• Noisy
  - the open & close switch does a great job of keeping heat/cold in but it is too noisy

• Hiking
• Car camping
• Backpacking
• Everyday
• High altitude
