I’m not one for writing reviews and I’m not easily impressed but with the bulldog razor and the clim8 coffee flask I’ve made an exception. The flask keeps my coffee hot and I mean hot for hours, I fill the flask two hours before I’m going to start drinking it, I’m a cab driver and have to get out of my vehicle to have a smoke and a coffee, unfortunately I have driven off 3 times with the flask still on the car roof but with no structural damage to the flask, it’s very robust. On the last occasion the rubber stopper was lost from the cap lid, I contacted HydrateM8 for a replacement that night and was responded to the next day. Replacement on its way - very impressed and I don’t impress easily. Thank you Robyn
