I always see people using the 32oz nalgene bottles with the gsi 18 oz cup. Or the canteen and canteen cup. Its awesome being able to slide the cup over the bottle. What I am having trouble finding is a smaller cup that will fit on the bottom of a 24oz bottle or maybe a gatorade bottle. The smaller system would be great for light weight trips. The few cups I have found the handle doesn't collapse around the cup. If someone can help me with any suggestions I would greatly appreciate it. Even better if the cup has a lid.

Thanks
