23ZERO Roof Top Tents

With a 23ZERO Roof Top Tent you'll have the freedom and confidence to explore

We've used our years of experience in the outdoor industry to refine our tents with a common sense approach. It's the small details we find that make the difference long term.
Things like the 3 Inch 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.
We re-enforce stitch the attachment point for the fly and tie points. We use just the right weight material in the right spots so we keep the overall weight down but give you all the features you grow to love with your 23ZERO roof top tent.

    Product Overview

    The Byron  4 + Person has a 72 Inch wide mattress, about the size of a California King bed. It comes supplied with the annex that will provide some extra space downstairs if required. 

    The Byron is equipped standard with a comfortable 3 inch thick mattress as standard and  has a waterproof base that eliminates the need for a condensation mat. The top of the mattress cover is cotton so you do not find your self slipping and sliding everywhere in bed. We finish our tent with an abundance of common sense features that deliver all the things you will come to love about your 23ZERO Roof Top Tent. The tent fabric is a not-too-heavy-not-too-light 260GSM Ripstop polycotton canvas (waterproof and mold resistant) stitched together with french seams and tape seam sealed, this will keep you dry in all conditions. Both the tent and fly are colored not to show the dirt and help keep an even temperature inside at all times - you might find yourself sleeping in as it's a comfortable color to be in, even in full sun.   All tents come with superfine insect mesh windows and doors to keep the bugs on the outside and have sky view windows as standard and the fly is easily removed so you can take the full advantage of this great feature. The internal poles are all wrapped and operate on metal fittings ensuring years of use and they are attached to the insulated base via stainless steel bolts. As this tent has the extension that covers the ladder we include a "snow pole" to help keep the cover tight eliminating water build up and excess pooling.
