Ok, I received my nano nets from REI today …bought both with my 20% off coupon. I started playing around with them in an ultamid 2.
These are just initial pictures….I didn't focus on getting everything nice and taut.
The first thing that I wanted to mention….is that both nets were over the specified weight. The Single, without stuff sack, weighs 3.1 oz instead of 2.9 oz. The double…weighs 4.4 oz netting only…5.6 oz with the pole, which is quite a bit over the stated 4.85 oz. I can live with the single being slightly over, but 3/4s of a oz over on the double? Yikes.
And…to answer my previous questions…yes, the stated widths are correct. So a single really is 48" though useable width is actually a bit less. You can still get two adult pads in there ->

I know what you are thinking…."that looks like garbage". Well, again, I didn't take the time to make it taut. Plus the ridgerests don't have any weight on them and they are on top of grass, still kind of rolled up, etc.
The nano material is actually quite elastic. Once I fully decide what to do when my new shelter comes in (I ordered a cuben supermid), I will sew small grosgrain loops onto the sides of the nano and with shockcord I can increased head room by pulling out the sides a bit. This would be very beneficial for the duo ->

I think its a much better fit here in the inverted V setup of the ultamid 2. I would increase the height a bit (just need a better attachment system for the top…still quite easy), and I would add grosgrain half way up the foot sides for tieouts to the door's buckles for holding back the door. It would really increase the foot space…lots of slack there…it would probably get the entire mesh off your body/quilt.
Of course…if I wasn't sleeping with family, I would probably setup the ultamid with a center pole and have two solo nets. I originally thought the duo net was going to be like 3.6 oz, so only half oz difference between the solo, but at 4.4 I would probably take two singles.
