Two doors and room for three backpackers. New Swivel Hub improves stability by up to 60%.

While Sierra Designs classified their three-person Sirius 3 as a three-season tent the dual doors and big mesh walls make it easier to cool and vent than other alpine three-season climbing tents. This is a roomy design that's ideal for camping backpacking and climbing in moderate weather conditions even if the wind kicks up. The Sirius 3 features Sierra Designs' Quick Pitch Swivel Hub a small metal swivel up top that locks the tent poles in place adding as much as 60% more structural support than conventional "crossover" tent pole configurations. The Swivel Hub also simplifies pitching so you're less likely to have your poles crossed (in a bad way)--especially if you're setting up camp in the dark. It features a two-door architecture inspired by CAD design that offers excellent cross ventilation. Your group can also sort hiking boots and climbing gear in the separated vestibules. Roomy gear pockets along the inside of the 31-square-foot interior space make it easier to sort out field guides GPS components and other important stuff. One thing to keep in mind is that the Sirius series does feature an optional footprint (sold separately) for floor protection but it cannot be pitched in a fly-only fastpacking configuration. Considering that the packed weight is less than five pounds many minimalist trios won't care at all.
