The Foster can is tall, narrow and thin walled (eg fragile). I decided a while back that saving a few ounces was not worth the hassle of dealing with such a pot. IMUSA makes two aluminum mugs that are around the weight you mention. They don't have lids but you can make one from foil. They have a handle that is riveted in place. You can cut the handle off to save a few grams. Here is a link to one that Walmart carries http://www.walmart.com/ip/IMUSA-Aluminum-Mug/15040696#Specifications On occasion they can be hard to find and not all Walmart stores carry them. They can sometimes develop minor water leaks around the lower rivet but seldom loose enough water to make any difference.
