Naturnest Sirius 1 Plus vs Naturnest Sirius 2 ABS
Both of these are Naturnest tents, so the question is not which brand to trust but which size and configuration suits your vehicle and how you camp. The Sirius 1 Plus and the Sirius 2 ABS share Naturnest's construction and warranty; where they part company is in the numbers below.
On weight they are effectively level — 75 kg against 79 kg — so the roof load question resolves the same way for both. Floor area is close to identical at 3.36 m² and 3.52 m², so neither wins on sleeping room. The Sirius 1 Plus lists $450 lower, at $1,549 against $1,999.
The Sirius 1 Plus uses ABS hard shell with aluminium honeycomb base panel; the Sirius 2 ABS uses ABS hard shell with aluminium-alloy frame. Canvas differs too: 420D waterproof Oxford outer; mildew-proof plaid Oxford inner against waterproof, UV-resistant polyester canvas (blackout, mildew-proof inner).
