GSI Outdoors Glacier Stainless Steel Bottle Cup
Price Paid: $8
This is perfect for solo trips. It's big enough to boil two cups of water, has handles long enough so you don't burn your fingers, is small enough to drink comfortably out of, is big enough to use as a bowl, and fits snugly around your water bottle so you don't lose space. It multi-tasks wonderfully, and will absolutely not break the bank.
