ARB builds off-road gear for the Australian outback, and their Altitude reflects that pedigree. The fiberglass gel coat shell and 380GSM canvas are heavier-duty than most competitors at this price point. At 234 lbs it is one of the heavier options, so confirm your rack and vehicle payload can handle it. If you need genuine 4-season capability with a popup form factor, this is a solid choice from a brand with decades of off-road credibility.
