Sierra Designs Sirius 3 - 3-Person 3-Season Tent

Keep your gear dry, your wallet full, and your load light with the bombproof Sierra Designs Sirius 3 Tent. With lots of space, this three-season shelter makes sure you and your two tent-mates stay mates. This lightweight tent tags along on trips between March and October. Sierra Designs' Swift Clips make pitching fast and easy. The innovative pre-threaded Quick Pitch Swivel Hub system cuts down on set-up time by cutting down on material and moving parts. The dual doors put an end to the midnight steamroll exits. Dual vestibules add 4 square feet of protected external storage space on each side of the Sirius 3 Tent. Funk-fighting, anti-microbial Tent Guard with Ultra Fresh treatment offsets your tent-mates' fragrance.

Bottom Line: Pack the lightweight Sierra Designs Sirius 3 Tent and let your buddies haul the heavy stuff (heheh…suckers).
