This ain’t your average camping cup—it folds flat, rides in your pack or back pocket, then springs open the moment you need a hit of hot coffee at dawn or whiskey at twilight. Built tough from BPA‑free, food‑grade silicone wrapped around two layers of stainless steel, it laughs in the face of single‑use trash.

Rugged & Ready

• Pocket‑flat design: Folds to 1–1.5″ thick—stash it in your gear, car, or commuter bag.
• Leak-resistant lid: Push‑in style gives you confident sips on trails or trains. One user said it “lets you enjoy …without losing a drop” YouTubeEddie
• Insulating sleeve: Keeps your drink hot and your hands safe. No skin scorched here.

Performance You Can Feel

Independent tests show it holds 140 °F water after 10 minutes—far better than an open mug and edging close to double-walled steel The Gadgeteer.

Real‑Talk Reviews

• “Compact and durable… I now have a mug to use when they only have paper or Styrofoam cups.”
• “Works great… great gift for Christmas or Father’s Day.” 
• Another blunt take: it’s sturdy, it folds flat, and it performs—though the straw can be awkward. You don’t need it if you trust the lid.

Why Iron Pines Stands Behind It

• Zero bull—you get what you see: durable, collapsible, everyday hero.
• Eco‑honesty—sick of disposable cups? This is one you’ll actually use again and again.
• Built to go places—camping, commuting, cliffside beers—this cup survives.
