23ZERO takes a common sense approach to roof top tent design. Years of experience in the outdoor industry has taught that it's the small details that make the difference long term. Things like the 3-inch thick mattress thats just the right firmness so side sleepers won't wake with sore hips and will feel like they have slept blissfully. The tie points for the windows are made from the same material as the tent so we don't create a water ingress point. Re-enforced stitching on the attachment point for the fly and tie points. And the just-right weight material in all the right spots to keep the overall weight down while giving you the features you'll appreciate more every time you use your tent.
