I have the Oilcamp XTS and it is 1 liter in size but weights 7.6 oz. I can fit a fuel can, small windscreen and my Soto stove inside of it in the carry bag. I purchased the Toaks 650 cup with lid and it arrived today from Amazon. It is small compared to the Oilcamp XTS. How many of you hikers use the Toaks? I know it can hold 1.5 cups of liquid, but I guess to me it just seems too small. I am new to lowering my weigh of equipment. I guess what I am asking, is it worth giving up the Oilcamp and using the Toaks. Should I have gone with the 750?
