Test: Klean Kanteen “TKPro” Insulated Bottle

The Klean Kanteen “TKPro” Model Insulated Bottle Tested: Top of Flop?

The TKPro is a high-performance, plastic-free thermal Kanteen. With its integrated double-wall stainless steel cup and 360-degree pour-through functionality, the TKPro features our new TK Closure™ internal thread design which provides cutting edge thermal performance for both hot and cold beverages. Whether sipping hot coffee miles from the nearest road or pouring ice cold cocktails in the heart of the city, the TKPro is your built-to-last solution.

So much for the ad blurb, but how does this luxury thermos hold up to the test of reality? That’s what we’re here to find out.

Materials

The plastic-free nature of the TKPro is the main reason I bought it in the first place, as it was the only one of its kind at the time. As such, it should come as no surprise that it consist of nothing but stainless steel and silicone.

For the health conscious hiker, there is simply no better material composition to wish for, and if it lasts the lifetime it should, it’s an very ecological option as well.

Finish

At first glance, this bottle is about as well made as a bottle can be. It looks and feels great; robust and really high quality. I especially like the brushed steel finish, but that’s a matter of taste.

As it turns out the actual manufacturing quality is a bit hit and miss with this product. You may get a good one or a bad one and you will only find out once you start using it. For some, the insulation works perfectly, as advertised. For others, it fails within a few weeks to months, or is broken from the start. There seems to be a problem with the seal.

You can test if yours works properly by simply filling it with boiling water, closing the cap, and giving it a few minutes. If the cap starts feeling hot, the insulation is broken and you can return it for a refund. Try again and better luck next time. I should mention that the RMA process was quick and painless. Customer service was great.

It’s a fair guess that the faulty component may be the “TK Closure™ internal thread design”.

It’s possible this problem has been fixed since I ordered mine, but I did receive one of the faulty ones and judging by the reviews, so did a lot of other people over a long span of time.

Functionality

If you’ve gotten your hands on a working model, the insulation works very well. Not as well as was advertised, though. At the time of writing, Klean Kanteen have removed the “12 hours hot” claim from the official product description, but it was there when I ordered mine last year. In reality, hot drinks stay hot for about 6-8 hours, depending on whether you heat it up with boiling water before filling in your drink. Long enough for day hikes, but not exactly impressive.

This may be due to my specimen having been faulty, but it only failed later on and rather instantly/completely from one day to the next. Them removing the claim speaks for itself though.

The “360-degree pour-through functionality” leaves something to be desired, namely a lack of mess. I’d recommend just opening it completely to pour.

The cup is a welcome addition, one that should be standard for insulated bottles.

Cleaning the thing is easy enough, and the silicone rings can be effortlessly removed and replaced.
