23Zero Onyx Triple X 1450 vs Femkes Lifun

The 23Zero Onyx Triple X 1450 and the Femkes Lifun 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 Femkes 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 Femkes Lifun counters with 74 kg, 2.75 m² of floor, 95 cm of headroom and sleeps 2.

The Lifun is 24 kg lighter at 74 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. Floor area is close to identical at 2.78 m² and 2.75 m², so neither wins on sleeping room. The Lifun lists about 7% lower than the Onyx Triple X 1450.

The Onyx Triple X 1450 uses oxide-coated aluminium extrusions with a honeycomb base; the Lifun uses aerodynamic ABS, waterproof, bottom fitted with upholstery. Canvas differs too: 320 gsm canvas with Light Suppression Technology (LST) against polyester mix with cotton 280 gr fabric, waterproof and fire-retardant. Closed, the Onyx Triple X 1450 sits 9 cm lower on the roof — 22 cm against 31 cm — which is drag you carry on every mile you are not camping.
