unfortunately the barebones 16' unit (frame + cover only) is $1700+ many of the peripherals are overpriced (like they bought them retail & then marked them up to cover expenses) and the frame may stand up to 147 mph winds but they give no actual numbers for the polymer cover
Looking at the size, options and price, I think I'll stick with a 4-season base-camp tent. I picked up a Ferrino Base Camp tent that's 4-season and 14' diameter so it's just a little smaller then the dome, but at $550, it's only 1/3 of the price
How long would you be staying in it? When I bough my first North Face tent and broke out the instructions. It said. "Do not set up in direct sun light" UV light can eat tent fabric up in as little as two months.
As long as needed... It's made of Oxford Polyester which I believe is the same material used to make boat sails, backpacks... so I'd expect it to hold up.
