A brilliant mug for walkkng or hiking.
It can attach to your rucksack or belt using the carabiner integrated into the handle.

Use it to add a little extra push for that last mile walking. You can put whatever you want in the tot flask, althoiugh my preference is some nice irish whisky to give an extra jolt to the coffee. 

Please be aware, I can no longer source the flasks with integrated gems in the caps. they will have a smaller carabiner to attach to the handle to further ensure thast any jolts or knocks will not free them from their holder.
