Reviews
Jessica Warren
I took my 30 oz Rocky Mountain Tumbler on a three-day camping trip in Estes Park, and it genuinely surprised me—my iced tea was still cold the next morning despite sitting in a warm tent. The engraved topographic design made it easy to spot among our gear, and even after being dropped on granite (twice!), it barely scuffed. The only thing I had to watch for was making sure the seal was properly tightened after a hot drink, but overall it became my most reliable piece of camp gear.

As someone who works long shifts outdoors, I needed something that could stand up to heat and dust, and this tumbler delivered better than expected. My coffee stayed warm well past lunchtime, and the lid never leaked even when tossed in my truck. The sweat-free exterior was a huge bonus in humid weather. I’ve tried a lot of insulated cups, but the Rocky Mountain one feels tougher and more stable in cup holders than most.

I bought the engraved National Park version as a gift for my sister, and we ended up fighting over who got to keep it. The engraving is incredibly detailed, almost like a miniature map etched in steel, and the tumbler held up beautifully during a weekend paddleboarding trip. It stayed upright in the kayak’s cup holder, and even after being splashed all day, the grip and finish felt secure. She now uses it daily for both tea and smoothies.
