Why this product
Why the ARB Simpson III Rooftop Tent with Annex?
The Simpson III is the only ARB tent that includes an annex, which effectively doubles your sheltered space. As a softshell fold-out, it offers more interior room than the clamshells but takes 3 minutes to set up. The 300GSM PU-coated ripstop canvas handles rain well. At 154 lbs for a 3-person fold-out with annex, the weight-to-space ratio is competitive. Best for trips where you plan to stay multiple nights at each camp.
