Here are some photos of my tent:

As you can see, the tent perfectly holds my Aerostich High-Tech cot -- though a taller rider might find that their bag rubs up against the tent walls in the night. I'm only 5'1" and the very bottom of my bag is often damp from condensation when I use the cot (even with the vestibules staked out).

The vestibules are great for my boots and riding gear (I keep my helmet and tankbag inside the tent -- I don't like a wet or buggy helmet in the morning!).

It has a LOT of ventilation for summer camping, which is my preferred time to camp anyway.

I also attached a Sierra Designs portable attic (manufacturer pic here) and leave it in the tent at all times. I put my Brunton Glorb LED lantern in the attic at night and can always see the tent from the outside (and can easily maneuver around or read in bed via the light).

The Sirius 2 is really easy to set up due to the clip system of the poles (no sleeves). It takes me about 5 minutes to set up, including lining up the footprint and clicking together the poles.

The coldest weather I've camped in with this tent so far had an overnight low of 30F. The warmest so far has been an overnight low of around 70F.

This tent came highly recommended from Becca, moto-camper extraordinaire, and I have to agree with her assessment. Two thumbs up!
