Klean kanteen flask

The flask is fantastic, just what I was looking for. If there was one thing I would love to improve on, is some way of not using silicon as a seal. Being totally plastic free would be my goal, but I am happy. Natural man had a great price, and delivered quickly. Would definitely buy this product, and use natural man again.

Klean Kanteen Insulated TKPro 1L Kanteen Thermos Flask

Pros:It does keep the hot tea in it. it easy to poor any liquids in it. So far its clean and has good acmes to clean it with a brush Top Cup is capable of holding the ring work for long time. Cons: Make sure you firmly tide the first top. the top Cup can unscrew quite quickly. It s quite noisy if you are at Bird watch or close to the animals. So far is the best flask i have had. I had cheep from Tesco,Cheep Stanly,Lifeventure 700 and that was quite long lasting one. I believe i can through it in to the fire to let the flame or mainly ash to warm the water in.Of course with out any tops on. I will recommend it for 3 and more days of walking in the wild.For work get the one from Tesco. Yes do you want good one for a regular adventure?You need to splash money to it. it.
