Well, I went and picked up my new HG 20* Incubator from the folks at the Hammock Gear shop. I'm absolutely loving this M50 material vs. the standard 1.1 ripstop. The brown I'd picked out initially came out a fantastic copper color once the down was inside which goes great with the grey interior.
On the scale I believe it was 21oz? With draft collars and suspension.
One thing I'll be looking for in particular is it's wind resistant properties. M50 is apparently just breathable enough not to have condensation issues but is more wind resistant than 1.1 ripstop. This hypothetically should enhance the insulating properties, having a reduction in loss of heat through convection. Hopefully this will negate the need for me to get a UQ protector as well like I was planning. Hypothetical ounces saved, score.
Take a gander..
