Cups and mugs are essential on backpacking trips, but they’re pretty bulky in your backpack. This Design Go Pocket Glass collapses on itself for easy packing, but it doesn’t look like it could even handle a trip through the dishwasher let alone a backing trip. If you need something compact, the Orikaso folding cups are among the most durable things out there, but folding it up whenever you want a drink is a bit annoying.
