What Our Gearhead(R) Experts Are Saying: "I keep the Drift 10oz Tumbler in my kit because it's the perfect size for a morning coffee or an evening pour by the fire. It's small enough to stash anywhere, yet it keeps drinks hot or cold for hours thanks to the double-wall insulation." From first light coffee to evening campfire cocktails, the VSSL Drift 10oz Tumbler is built to keep pace with wherever the day leads. Crafted with durable stainless steel and finished with VSSL's rugged, minimalist design, this cup ensures your drink stays at the right temperature-whether you're moving fast through the city or slowing down off the grid. We love how its compact size makes it easy to pack, toss in a bag, or carry in hand without taking up space. The double-wall vacuum insulation locks in heat for morning brews and keeps cold drinks chilled when the sun's out, so you can enjoy your favorite beverages the way they're meant to be, anywhere.
