フロンティア ウルトラライト折りたたみカップ

This thing weighs almost nothing in my pack, and the glass reinforced nylon feels way sturdier than the silicone cups I've used. Held hot coffee on a chilly morning without any flex or weird taste.

I've had flimsy collapsible cups before that tipped over at the slightest breeze, but this one's base and ergonomic shape finally feel solid enough for a real camp setup. It's noticeably lighter than my old silicone one, and the glass-reinforced nylon gives it a rigidity that makes drinking from it

Weighs next to nothing, which is perfect for tossing in a daypack, and that glass-reinforced nylon feels far more durable than the flimsy silicone cups I've tried before. Handles hot coffee without flinching, and it holds up well after a few rough trips.
