US GI Type Stainless Steel Cup
The US Canteen system has been in use for decades and represents fantastic value so if you favour the American canteens this is a must, it fits perfectly onto the bottom of a 1 quart canteen and is ideal for making a brew or even using for cooking. It will save weight as there is no need to carry mess tins as well.
Buy it individually or as part of a set it will last you years and is ideal if you want to travel a little more light weight.
Excellent choice even if you are not in budget.I had used one for years when I was serving,but it was made from aluminum.This version of stainless steel is much more rugged and bomb proof!
Along with the lid you can buy, I believe although not quite as big this is better than the crusader cup. Fits the generic Nalgene bottle and is superb value for money. If in doubt I suggest you buy it. I have used it on gas, fuel tablets, bush box xl and a fire. It is the only one I know of that the folding handles lock into place. Superb.
