Insulated Water Bottle

 

These things are fantastic! I own three so far. Prior to purchasing this insulated Thermos I picked up a wide mouthed generic Thermos from K-mart but was major disappointed as my coffee would be only warm in a matter of a couple of hours.

Yes there are a little on the pricey side. At the time of writing this article I own three of these wide mouthed Thermoses.
Main use if for making bulletproof coffee for breakfast. That is a Klean Kanteen in the Video below.

There is no need to tighten the top too much, as the seal of of good quality. Over tightening may cause the internal grommet to flip and may result in leakage. Easy does it.

The circumference is not too thick so it easily slots into those side areas on backpacks designed for water bottles. Also leaving area to spare.

Molded into the screw on lid is the ability to attach it to your bag via a for lack of a better word rock climbing clip.

The cap feels very solid and of very high quality. You could probably tow a car using the cap.
