Review on 🆕 New 2018 Klean Kanteen Wide Mouth Stainless Steel Water Bottle - Single Wall, Leak Proof Interior Cap by David Fields

In general, I like it very much. Keep in mind that this is a single wall mug so it won't stay cold forever like a "YETI" or other brand's double wall mug. I bought this as part of a survival bag I'm building and the fact that it's metal and single walled allows me to boil water in it if needed. The lid closes securely and the rubber seal prevents leakage. If I had one thing to complain about, it would be that I wish the opening was a little rounder and not as sharp. It's not a problem, but a rounded edge would be nice.
