Silk, Baffled, Hooded Down Vest

Ok, weird. I did a pic test on test forum before posting, worked great, did exact same here, but 7 photos didn't go up. Trying again. If it doesn't work this time, I'll have to get some help.

Brad,

Good job! You should go professional! All my MYOG projects while functional, well … look like MYOG :-)

I have been considering a down vest for my next project and would love an instructional post, even better with pictures taken while assembling if available.

Keep this up and Patagucci will be in trouble!

you have my empathy and my respect – i have dabbled in hooded prototypes and when you say PITA, i know what you mean. but it is really, really beautiful. congratulations on an extremely impressive project.

Not bad at all.
If you want to sketch out an article (rough outline first), please do so and send to me: roger@backpackinglight.com/

> The absolute bear of it was getting all the pieces sewed together–and then having to bias tape all the exposed-edge seams on the vest.
Yeah, I know, and sympathise.
Have a look at commercial units for more ideas about how to make these things with less hassle over the details. It can be done, but takes a bit of planning. One thing to consider is overlocking the edges and concealing them. Can be done with an ordinary sewing machine as well as with an overlocker, but takes a lot of planning.

Cheers

Thanks for your comments, Michael and Colleen. When you've got the piece in your hands and you're noticing mostly errors, it's great to have the positive reinforcement–and empathies. I love the thought of competing in the market, but it'll take some more sewing time (or hiring practicing professionals) and a whole bunch of capital and a compelling line…

Roger, thanks for the ideas. I tried to mentally dissect the things I have (didn't have the heart to cut 'em up), and tried to sorta do the same. There's one stitch I've seen that I think is a French seam that I probably could've used. Overlocking edges and CONCEALING sounds good :). I'll take you up on the article sketch-up–thanks!

there isn't a single garment or piece of gear i've sewn whose imperfections and "oopses" i don't recall. if you're like me, you'll never be 100% happy with anything you make. But 99% satisfied is still great.

Amen!

I think the effort (and results) are absolutely awesome. I a bit 'baffled' about the amount of fill you've used though. At 2 inch baffles, 12 ounces of good quality down would be enough to fill a sleeping bag. Overfilling the baffles doesn't necessarily make the vest warmer, just heavier. Or were you using lower fill power down? Either way I'm sure you will be toasty in it.

My SummerLite, with 2 ounces of overfill for a total of 11 ounces of fill, should theoretically (per statistics) have the same 4" of total loft as my vest. The pocket area of my vest has 6" total loft. The hood probably has 6-8" total loft, haven't checked. (I made this thing thinking about sitting in a tree stand, unmoving, for 6 hours in the middle of winter.) I expected the project to take about 7, maybe 8 ounces of down using the 800+ Thru-Hiker down I got. I'm confused about how much down I used, too. But like I said, every time I pulled down out of the vest, I lost loft, no matter how I fluffed and distributed the remaining stuff.

I'm better at conceptual thought than straight mathematics; one thought I had was that if I cut the vest in half and put the pieces end to end (collar to tail) the overall length would be about as long as my Summerlite, especially if considering the hood. Theoretically the SummerLite should have 2-2.5 inches of down on one side, which would be about what my vest has. In practice, I've found that I need to put most of the down on the top layer of the SummerLite to totally eliminate cold spots. So I think the fill is actually pretty close to realistic-ish.

There's been talk before about how fill power affects loft with different weight fabrics. Given that I used 3-3.5 yards of fabric and fabric weight was 11 ounces, that calculate to 3.1-3.6 ounces per yard for the fabric (ouch!!!). I'm wondering, given that fill power is calculated with a set amount of weight, if the overall weight of the fabric somewhat reduced my loft, requiring more down to compensate.

Thoughts?
Brad

Yes, a heavier fabric will restrict loft more than a light one. Even so, it seems a lot of down. Oh well, still a nice vest.

Yeah, it sure does seem like a lot of down, eh? Ah well. Thanks Allison, I appreciate your comments!

I'm doing some research on lighter shell alternatives in this vein, have one possible choice right now.
