Naturnest Sirius 1 Plus vs Overland Vehicle Systems HD Bundu 2 Cantilever
The Naturnest Sirius 1 Plus and the Overland Vehicle Systems HD Bundu 2 Cantilever 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. Naturnest and Overland Vehicle Systems take noticeably different approaches to the same problem.
The HD Bundu 2 Cantilever is 7.900000000000006 kg lighter at 67.1 kg against 75 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 3.36 m² and 3.35 m², so neither wins on sleeping room. List prices are within $150.99 of each other, so price is unlikely to decide this one. Overland Vehicle Systems also backs the HD Bundu 2 Cantilever for 4 years against 1.
They open differently: the Sirius 1 Plus is a fold-out and the HD Bundu 2 Cantilever a clamshell. That is not cosmetic — it decides whether headroom is even across the tent or tapers towards one end, and how much of the roof the tent occupies when closed. The Sirius 1 Plus uses ABS hard shell with aluminium honeycomb base panel; the HD Bundu 2 Cantilever uses high-impact UV-stable ABS over aluminum honeycomb base. Canvas differs too: 420D waterproof Oxford outer; mildew-proof plaid Oxford inner against 280g rip stop poly cotton canvas body, 420D polyester Oxford rainfly. The Sirius 1 Plus adds the ability to carry cargo on the shell, which the HD Bundu 2 Cantilever does not offer.
