You're right, it isn't – but as Luke90 says, it's quite light for what you get. I think you would struggle to find a lighter twin-wall design as stormproof as this. That said, I do pick up on the fact that I'd prefer a lighter tent in the review.
MLD pyramid shelters and Trailstars are lighter, and arguably as wind-resistant, but they're a completely different beast and many backpackers are not ready to make the jump to a floorless shelter.
