Don't think of the Rig 21 as just a large tarp suitable for a small group: it is also a useful addition to any outdoor person's kit list.
As a tarp it is pretty big and this helps when you are camped for a few days as you can sleep and hide from the rain pretty easily. It's also a pretty big awning, so even if you are just camping out with the family this makes a great dining shelter or massive windbreak. We have even found ourselves using one on the side of the M1; an awful lot cosier than if we didn't have it.
There are cheaper alternatives around, but not with this performance. With both the Rig 21 and Rig 7 we have chosen a fabric that is awesome, rather than one to hit a price point. Pretty much all the cost goes into the fabric, so if we double the cost of the fabric then we pretty much double the cost of the tarp.

My minimalist tarp set up using the Alpkit rig 3.5. Absolutely crazily small pack size but full coverage. This set up was similar in size to a typical hooped bivvy tent so only really suitable for overnight.
