Unicamp’s Sienna Pop Top brings mid-sized minivan camping back to the masses

Overlanding-centric vans are all the rage these days. But they’re often very pricey and not designed to be practical daily drivers. For campers looking for something a bit more versatile — something to pull double-duty even when you’re not camping — it’s hard to beat a traditional minivan. Unicamp agrees, which is how its Sienna Pop Top campervan add-on was born.

After more than a year in development, the Korean campervan modder finally released its much-awaited Sienna Pop Top stateside. It’s not a standalone vehicle but rather an add-on package available to Toyota Sienna owners. Once installed, it converts the otherwise ordinary mid-sized minivan into a go-anywhere, road-ready basecamp. It’s more conspicuous than most dedicated campervans while maintaining a mostly stealth silhouette to help you blend in for camping situations where you don’t want to stick out to the locals. With the press of a button, the electric Pop Top raises effortlessly to reveal an 84-by-37-inch sleep space with enough room for two adults (up to 485 pounds total!).

The cabin of the donor Sienna remains unchanged, save for the pass-thru hatch between the interior and rooftop tent. That means the final campervan “build” (if you can call it that) boasts all the features found in a factory Sienna, plus three-row seating. It also includes the standard hybrid powertrain and, when attached to a Sienna Woodland Edition, seven inches of ground clearance and a 1,500-watt inverter with a 120-volt AC outlet — perfect for car camping.

The Sienna Pop Top is available directly from Unicamp for a flat fee of $16,000. You’ll need to bring your own Toyota Sienna, of course. Any fourth-generation model year (post-2021) will do.

I tried the Yozma IN 10 Pro electric dirt bike, and it was nothing like riding an e-bike

I’ve spent plenty of time riding e-bikes, but I’d never ridden an electric dirt bike before. When I had the opportunity to try the Yozma IN 10 Pro, I was curious to see how the two would compare. As it turns out, they’re completely different experiences. The IN 10 Pro is fast, surprisingly loud, and considerably more powerful than anything I’d ridden before.

I didn’t push the bike anywhere near its advertised top speed of 50 mph, and I didn’t need to. Even at lower speeds, riding the IN 10 Pro was a lot of fun. Between the powerful acceleration, responsive steering, and the way it handled gravel and dirt, there was plenty to enjoy. And despite all that power, the ride was surprisingly comfortable, even over uneven ground. It didn’t take long for me to understand why people love riding dirt bikes.

Arc’teryx x BEAMS: The blend of Alpine tech and Tokyo style

Arc'teryx x Beams

The new Arc’teryx x BEAMS collection celebrates the brands’ 25-year collaboration and the blending of technical function with street-savvy style. The line highlights a re-creation of the 1998 Arc’teryx Theta hardshell, a Gamma softshell jacket, and Jogen bouldering pants. All come in the signature Kōyō color palette, modeled after Japan’s autumn leaves.

I wore the Gamma Jacket and Jogen pants during the fall changeover in Virginia’s picturesque Shenandoah Valley, testing for warmth, wind resistance, and style. Here’s my take.

More than a name: Meet Eddie Bauer, the true-life explorer behind your outdoor brand

Clothing, Hat, Face

From the time I was a little man, I excitedly tugged at the shirt tails of my father and grandfather every time they left the house to do anything relatively outdoorsy. They would leave the house hauling gun cases, fishing poles, camping gear, hiking packs. The men of my life loved everything adventurous, and they would do it every chance they could. When I was big enough, I would be allowed to come with them. I got my own boots. I procured my own active wear that could resist the weather. I opened my own parka for Christmas. Not only was I now in the same boat with them, in the same tent with them, and in the same deer stand with them. I also wore the same brand as them. Eddie Bauer was their go-to, and it had become my go-to.

But what was it about that brand? What was it about the man behind the brand that became the man’s best friend in the wilderness? Well, here is what you need to know about the guy who ditched the work world to open an outdoor brand simply so he could go outdoors all the time. And made it possible for my grandfather, my father, and then me.
