If you’re traveling with a crew, space is your most valuable resource. But not all 4-person tents are created equal. In our latest comparison, we break down the nuances between the 23Zero Armadillo Horizon 3 and the OVS Everest XD 4 to help you decide which belongs on your roof.

The Common Ground

Before we get into the differences, it's worth noting that both tents are top-tier aluminum shells. They both include:

• High-quality telescoping ladders and mounting hardware.

• Built-in LED light strips and boot bags.

• "Stargazer" windows for night sky views.

• True 4-season protection.

1. Fabric & Durability: 900D vs. 320GSM

The first major difference is the material.

• 23Zero Horizon 3: Uses a 900D (Denier) polyester. It is incredibly tough and features 23Zero’s signature LST (Light Suppression Technology), which keeps the tent pitch black inside—perfect for those who want to sleep past sunrise.

• OVS Everest XD 4: Utilizes a 320GSM ripstop canvas. This is a more traditional, breathable material that feels classic and heavy-duty.

2. The Mattress Showdown

A bad night's sleep can ruin a trip.

• 23Zero: Comes with a self-inflating mattress. This allows you to adjust the firmness and, more importantly, deflate it to create extra room for storing sleeping bags and pillows inside the tent when closed.

• OVS: Features a high-density fixed foam mattress. It’s comfortable and ready to go instantly, but it doesn't offer the same "squish" factor for internal storage.

3. Windows & Ventilation

• 23Zero’s Big Win: The Horizon features massive 4-foot windows and a unique auto-deploying awning. When you pop the tent, the awning over the door sets itself up, saving you the hassle of spring poles.

• OVS Everest XD 4: Follows a more traditional "box" design. While the windows are plenty large, it lacks the panoramic, airy feel of the Horizon’s massive side openings.

Which One Should You Choose?

The 23Zero Horizon 3 is for you if...

You value "blackout" sleeping conditions, want the easiest possible setup (auto-awning), and need the ability to store your bedding inside the tent thanks to the inflatable mattress.

The OVS Everest XD 4 is for you if...

You prefer a traditional, bomber canvas feel and don't mind the extra 50 lbs of weight for a tent that feels like a literal fortress on top of your rig.
