A LEAKY DISASTER
Seems like a good idea, but just another example of how GSI should stick to making metal dishes.
Pros:
-Looks pretty
-Can be hung from a bag
Cons:
-Perforated lid that leaks as fast as you can pour it on yourself or your gear
-Mouth piece lid also doesn't seal, not sure why it even has one when there is a big hole drilled through the main lid. Maybe that wasn't a big enough leak to meet GSI spec.
-Also leaks out the o-ring seals inside the cylinder, will shoot boiling water at you on occasion.
-Almost every other review says it deforms and begins to leak so bad it won't even make coffee.
Hilariously poor.
I bring the large Contigo mug, It holds a Large McD's coffee perfectly. Never had an an issue with it with CATSA.
