The NaturNest Sirius 1 Plus XL is a 4-season hard shell rooftop tent built for families and small groups who want real camp comfort without slowing down setup. It sleeps 3-4 on a king-size equivalent interior with a full power suite — Anderson connector, AC port, heater port, and dual LED lighting — plus dual skylights for stargazing and blackout fabric for mornings you want to sleep in. Pop it open in 15-30 seconds, camp anywhere a vehicle can go, and pack it back down just as fast the next morning.

Basecamp Is Wherever You Are

Trailhead, beach, or backroad pull-off — drop the ladder and you're home. Everything else in your rig builds around it.

One Person, One Minute, Done

Zippered ladder pouches keep boots, headlamps, and odds and ends off the tent floor and within arm's reach when you climb down.

Less Setup. More Sunset.

Pack it up just as fast the next morning — more trail time, less time spent breaking down camp.

Backed for the Long Haul

Every NaturNest tent ships with a manufacturer's warranty — so you're covered mile after mile, season after season.

Wake Up Above It All

Off the ground, out of the mud, and with a view no ground tent can match.

Every Season. Every Adventure.

4-season rated construction — from summer trailheads to snowy basecamps, you're never waiting for the right weather window.
