GSI Outdoors Nesting Wine Glass Set

The GSI Outdoors Nesting Wine Glass Set consists of two collapsible wine glasses made from BPA-free copolyester, 275 ml each. The screw-on stem detaches and nests inside the bowl after use, so both glasses pack down to a small footprint in a pack or car — the whole set weighs 136 g and stands 229 mm tall with a 79 mm diameter when assembled. This is more of a camp-comfort item than an ultralight trekking piece — copolyester is tougher than glass, but it's still a hollow object that takes up its own volume in a pack even when it collapses flat. It suits canoe or raft trips, car camping, and campfire dinners where comfort matters more than shaving grams. The material is BPA-free and holds up to repeated washing, though the data doesn't specify dishwasher or temperature ratings. For strict ultralight backpacking, an item like this is typically treated as a deliberate luxury — a trade-off between the campfire experience and a minimal base weight.
