Great quality and as another reviewer stated you can feel da heat baby! But that is not a bad thing as I make full 20oz cuppa hot coffee and usin da lid it keeps it hot around 2hrs so I can savor dat hot juice. Also I will definitely enjoy this outside in colder temps as you have a hand warmer. Shout out to Matt for great customer service again as usual.

Overall it’s a decent cup. It’s made of pure titanium and holds 600 ml, which is why I bought it — so the C8 oil I blend into my coffee wouldn’t have any plastics to react with.
The double-wall insulation is the weak point, though. When I fill it with hot liquid I can feel the heat coming through the walls almost immediately. Judging by the dimensions it appears to have a thinner gap than other double-walled containers I’ve used. I’d say the thermal performance is better than a ceramic mug, but nowhere near what I’ve experienced with other double-walled cups — and, frankly, a bit below what I’ve come to expect even from much cheaper insulated options.

Beautiful design, joy to use
