Black Diamond Eldorado Tent. When you're spending a night high up on the side of some steep, glaciated peak, a few things become clear when it comes to tent selection. One, there aren't a lot of nice and easy flat spots to pitch a tent on way up there. And two, carrying a heavy tent on your back when you've been supporting yourself on the front points of your crampons all day isn't any fun at all. So when you leave the comforts of your big base camp tent behind and enter the vertical world, you need a tent that's lightweight, compact, and still able to withstand sudden storms. The Black Diamond Eldorado is just that kind of shelter.
