Build-Test-Fly Tumbler-10oz Stainless Tumbler

This 10oz stainless steel tumbler keeps drinks at the temperature you need and slips easily into a hand or cup holder. The distressed flag graphic and bold wording give it a rugged, lived-in look — like a trusted tool that’s been abused in the hangar. It feels sturdy in the hand, with a vacuum-insulated double wall that locks in heat or chill, and a clear push-on lid that seals with a rubber gasket for spill resistance. Lightweight and low-profile, it’s the kind of flask you reach for when you want a reliable sip after projects are done for the day.
