OK for motorcycle camping.
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.
First of all, it has a great space to weight ratio. It offers 41 square feet of floor space and 3 feet, 8 inches of headroom yet packs smaller (5-pounds, 4-ounces) than most other 3-person, 3-season, backpacking tents. Furthermore, it is reasonably well ventilated and very easy to set up, even in the dark.
The primary limitations of this tent are its short length (7-feet long) and its poor rainy weather protection. The short length means that you will likely touch both ends of the tent when you stretch out (especially if you are 6-foot, 2-inches tall like me). Touching the mesh on the double wall side with your head may not cause a problem but touching the single wall side with your feet will likely soak the bottom of your sleeping bag from rain or condensation. If the rain gets very hard, the vestibule area will become wet and you may have to enter and exit the tent on your hands and knees in the mud.
One other limitation is that the door zippers can easily snag at the top of the door where the zipper cover tapers down to the material. Once you become aware of this problem, you can prevent it by using your fingers to push the material to the side when zipping the door at the top.
In conclusion, it may be a good choice if you are less than 5-foot, 10-inches tall and have limited packing space. But be aware of potential problems in rainy weather.
