It’s -35° and four hours later the tea is too hot to drink.


  • * Keeps it very hot
  • Lightweight
  • Large cup/lid
  • Ergonomic shaped
  • Spill proof spout
  • Reasonable priced

I purchased two of these 1Lt bottles for treating clients on winter day hikes. 

They have done everything that I expected. I usually fill them twice a day and they handle the wear and tear of daily use.

The stopper is well built and has a spill proof gap that is great for serving tea. I have also forgotten and left the stopper loose and the cup/cap sealed the top and kept my pack dry.

The canister shape does not take up excess space and is easy to hang on to.

Of course, most importantly, I have been out for all day in -40° and tried to photo the steam of the hot tea coming out of the cup.



I'm giving your review a vote, because anyone who can say "I spent all day in -40 weather" really needs some support. :P
