Thinking about the scrim material, it would be great to have a 3D structure made of it – like corrugated cardboard. The result would be light,compressible and will trap some air for more insulation.

I get it now, at first I thought it was a 'quilt' but it's a multilayer bag. Waking damp is ok on a fine day, but the UK's maritime climate is too unpredictable. I'm buying a Spinnshelter off gear swap, so the condensation can roll off that. Maybe the right summer quilt would be a wicked fastbag summerweight long. 12oz with down in. Hard to find secondhand though.Jul 22, 2008 at 11:21 am #1443978Rog,
I just got some down off the forum and would be willing to make you a bag with it.
Jul 22, 2008 at 11:36 am #1443981Nice offer Tim, I saw the down befre you grabbed it but I don't have the needle skills, metalwork is my forte.
How about a deal involving some cash plus a couple of my uberlite 2oz kelly kettle/stove combos?I'd like a no frills quilt with enough width for side sleeping and a closed footbox for solo only use. En deux the WM wins.
There was a couple of yards of black event on gearswap too. How about that for a WR/breathable top? Handkerchief linen would be nice for the lining, but too heavy and insufficiently downproof I guess. I have some spare green parachute nylon I could send over, or do you use something lighter still?

I will move this conversation to e-mail

Jul 22, 2008 at 11:58 am #1443990oops, epic not event. Too late, you grabbed it. Should be fine anyway?
Jul 22, 2008 at 12:02 pm #1443991nothing is final yet so i can back out if you want
Jul 24, 2008 at 1:33 am #1444288I've ordered a down quilt from Tim. Just thought I'd put that on the record in case he starts playing favourites wih his fellow countrymen when the queue starts to form. :-)
Jul 24, 2008 at 1:58 pm #1444400at this point i have no plans of making any furtur down items. So put your tounges back in your mouths.
After i do this quilt that may change, but don't get your hopes up.

Jul 24, 2008 at 2:58 pm #1444409Roger. I have a black, epic shelled quilt. It's great for the damp UK climate. Water just runs off it. Being black, any dampness dries pretty quick too. ;)
May 16, 2009 at 1:50 am #1501626Well I used the quilt Tim made me for the first proper outing last weekend. Fantastic.
It's longer than a long golite ultra 20 and weighs less by a fair margin. I slept solidly under a Gatewood cape on a big agnes clearview inflatable with a cheap 2 season foam mat thrown on top of it. Ambient temp was about 6C – 44f. I don't use a bivy.
I wore my light down jacket over a cotton T shirt as I asked Tim to bias the down to the foot end for me. On my legs I wore some acrylic/wool man tights and some light rohan walking trousers.
May 16, 2009 at 8:25 am #1501640Rog,
I would like to see pictures of your completed quilt, any chance?May 16, 2009 at 2:08 pm #1501669Thom, I'd be delighted to show you pictures of Tim's handiwork. I'lltake some snaps in daylight tomorrow and post them.
May 18, 2009 at 6:01 am #1501900Here's the quilt Tim made for me.
.
.
Custom made to my spec.
78" long by 48" at the head end tapering to 26" at the foot.
6oz 900 FP down, biased to foot end.
1.1oz nylon top and bottom.
Epic ends to resist condensation
Snaps and drawcord to close foot, straps for comforter conversion, drawcord at head.
17oz total weight – amazing for such a large quilt.May 20, 2009 at 6:32 am #1502400My only issue is with the quilt is how much the down slides around in the baffles. I think I have found the answer to this. I just got 10 meters of Colin's row cover (horticultural fleece) off ebay for a couple of pounds. It's a thin spun polypropylene matting which weighs around 20g/m2. A layer between the shell materials above and below the down would help stop the down shifting a lot, as it's quite 'snaggy'. As it has some insulation value in it's own right, you could propably reduce the amount of down used by a couple of ounces too, which saves $$$.
In fact, I just did an experiment by concertina-ing the 10m of row cover and getting under it, and pulling a 1oz/yd nylon sheet over the top. It was warm. Total weight, 310grams or around 11oz.
I feel a myog project coming together.
May 20, 2009 at 7:52 am #1502417Roger,
Thanks for posting pictures of your quilt, it looks very nice. I enjoy seeing Tim's work, he always does a nice job.Thom
May 20, 2009 at 9:52 am #1502441Nice quilt indeed. It seems alot like my JRB Shenandoah Quilt however. Same dimensions, but the JRB is 1oz lighter, uses 800+ and is rated to 40-45.
May 20, 2009 at 10:22 pm #1502645Rog,
are you sure it's only 78" long? I like a quilt 80 (do use 78 sometimes) but you're another foot over my head (or like 6").-Tim
May 20, 2009 at 11:18 pm #1502658Tim, I measued it with a foot rule, maybe I miscounted. I'll check again. It does come right up to my nose with the footbox closed.
