Synthetic overbag DIY number 3

Postby Moondog55 » Sat 30 Dec, 2017 8:38 pm

As good as my Nunatak overquilt is; it isn't warm enough.
I'm going to tackle another idea but I need some design help as I'm not sure how to handle the head area of a Gerry Cunningham "Mountain Sleeper"
The Mountain Sleeper is basically a top quilt with a full length pad sleeve sewn to it
RSbtR had some offcuts of APEX insulation very affordably priced so I will be layering 3.6# and 2.5# [ because that was what was cheap, 2 metres of 3.6# and 3.5 metres of 2.5# ] plus a small scrap of something thicker for the footbox
I have no real problem with the sleeve or the basics of the quilt itself.
I'm wondering how I will tackle the hood area tho
I'm also wondering whether I should use a single zipper on the easy side [the Left so I can use my right hand] or if I should use 2 zippers, one on either side and what fabrics to use on the bottom of the shell.
I have also asked this same question over at BPL because some of the members there are more familiar with deep cold conditions.
A layer of 3.6 plus a double layer of 2.5 over the torso should be good for a 20C boost in temperature rating

There is every possibility that I'm going to get Evan at TerraRosa to sew this up when i get the design done. It would be cheaper than buying a new sewing machine

Well my order from RSBTR has just arrived and the off-cuts were/are a little bigger than described and conversation with the company says that I will not need to have any more than the two layers separated by the scrim.
So I am going to be offering the scrap to somebody who can utilise it
