From Campmor:
"The Sierra Designs Sirius 3 backpacking tent will sleep 3 people at a nice sub 6 lb weight. This is also a great tent for 2 people who want more room at a more than reasonable weight. This hybrid style (half single wall - half double wall) is freestanding and very easy to set up. It is has about a 50% mesh body for great ventilation and stargazing should the opportunity present itself. The other half is a single wall waterproof material, this combination saves weight without compromising function. It has 2 doors, 1 on each side, so each camper has their own door, except the person in the middle who gets to choose who they climb over to get out. The innovative aluminum frame has a swivel hub to save weight and because it keeps the poles together it makes setting the tent up even easier. It is also easy to set up because of the all clip design which also promotes better airflow under the fly and that's what helps keep you comfortable with a minimum of condensation. Go light, get Sirius. Sleeps 3 Main fly and floor seams are factory taped with PVC free seam tape to keep you dry Swivel hubbed frame stays together and sets up in a snap Freestanding design is stable and easy to set up Super Seal Bathtub floor wraps up the sides and keeps you dry DAC PressFit aluminum poles are strong and reliable - they are less prone to breakage in part because of their unique means of joining the poles with a precisely press fit, tight tolerance ferrule - which greatly reduces the likelihood of failure as opposed to ferrules that are glued or peened in place - and the process used to make them is far less polluting than other methods Post and grommet attachment of tent to poles with locking pole tips is reliable and fast on set up or take down 2 side entry doors for fast and convenient entry or exit Half fly and waterproof walls keep the tent dry Inherently lighter design is optimum for those who want to save weight Large mesh panels are great for ventilation and stargazing 2 half vestibules can shelter things from all but driving rain Color coded pitch system for even faster set up Body to pole attachment is with the ultralight SD clips - clips speed assembly and allow more airflow under the fly Internal pockets and gear loops make organization and stuff stashing easy All carry bags and stakes included Import."
From Altrec Outdoors:
"A tried-and-true X tent, the Sirius 3 from Sierra Designs is simple and light (under five pounds), with two doors and vestibules. Updated for '09 with a polyester fly and black mesh for better visibility. The hybrid single- and double-wall design of the Sirius 3 pares down weight which means an easier walk in for backpackers."

It wouldn't be great in extremely wet conditions if you had to traverse in and out, but waiting out a heavy rain for the night with no pee breaks was fine."

The Sierra Designs Sirius 3 is one of the five tents I have used on past motorcycle camping trips. I bought it at an REI scratch and dent sale and have used it on a few trips. My observations of the tent agree with the comments made by other reviewers."

The only foreseeable issue you may have with this tent is that it's a little bit of a tight squeeze for three people."

Pros:
(1) Extremely light-weight
(2) Easy to pitch by yourself, and especially fast pitching it with a partner.
(3) Great ventilation
(4) Double entry doors
(5) The Quick Pitch Swivel pole system seem to make it more sturdy during strong wind gusts."

Its drawbacks are small interior room for three; it is really not adequate for three grown people."

At 7 ft length, you'd have to be 5'6" or so to fit lengthwise without bumping your sleeping bag against the single-wall. From my experience, water will leach right through a tent wall if you rub against it."
