Where can you find good quality 950FP down that is water repellent DWR treated?
I think I might go for a DIY project if the premium product launch and wait time start to get a bit long.

Would love to get an Incubator in 950 though.
Looks like the 20F EE Revolt in 950 down FP Long is lighter, both owing to the higher down FP (10.95oz vs 11oz) and more significantly owing to the fabric (6.40oz vs 9.25oz deadweight).
Unfortunately it lacks some of the HG refinements of the HG underquilts such as the draft collars. So DIY would maybe bring the best of both world while HG finish fine-tuning their design.
