23Zero Onyx Triple X 1450 vs Harva Outdoors Sundet 2.0
The 23Zero Onyx Triple X 1450 and the Harva Outdoors Sundet 2.0 are both hardshell tents in the same part of the market, which makes them a genuine head-to-head rather than a comparison across categories. 23Zero and Harva Outdoors take noticeably different approaches to the same problem.
By the numbers, the 23Zero Onyx Triple X 1450 brings 98 kg, 2.78 m² of floor and sleeps 2. The Harva Outdoors Sundet 2.0 counters with 57 kg, 2.24 m² of floor, 160 cm of headroom and sleeps 2.
The Sundet 2.0 is 41 kg lighter at 57 kg against 98 kg, which on a factory roof rated for 68 to 75 kg is often the difference between a legal fit and a rack upgrade. Inside, the Onyx Triple X 1450 gives 2.78 m² of sleeping floor against 2.24 m², about 24 percent more, though both are rated for 2. Their list prices are within a few percent of each other, so price is unlikely to decide this one.
The Onyx Triple X 1450 uses oxide-coated aluminium extrusions with a honeycomb base; the Sundet 2.0 uses powder-coated aluminium clamshell over a steel-reinforced aluminium floor with 3-layer honeycomb panels (23 mm insulation). Canvas differs too: 320 gsm canvas with Light Suppression Technology (LST) against PU-coated 300 g/m² poly-cotton, 4000 mm water column; tent fabric rated 3000 mm. Closed, the Sundet 2.0 sits 10.8 cm lower on the roof — 11.2 cm against 22 cm — which is drag you carry on every mile you are not camping.

Which one to pick
Take the Sundet 2.0 if your roof load limit is the binding constraint. Take the Onyx Triple X 1450 if you need the sleeping room more than you need the lighter tent. Beyond that the feature rows below — heater port, skylight, annex, cargo rails — are where the remaining difference lies.
