customized jarbidges?

After I did some calculatin' I realized about the same thing weight savings wise. I think it was .25 oz different roughly for the entire quilt. I love the way you put things in perspective though. And thanks demo for saving me some money with the m50 and m90 fabric. Last thing, finished weight of m50 is .57 oz/ft I believe...thru hiker has the specs on it.

14 oz on the 50 degree jarbridge, and 20oz on the wife's 30 degree one. You might save a little by going to the Apex insulation and increase your degrees of warmth a bit as well..check with Paul.

Nope won't save weight with the standard APEX. It's the same weight of insulation but it is more compressible and warmer.

Their would be a weight savings with m90 but only a little. I don't feel durability would be an issue...lets get real it's a under quilt not a jacket, pack, pants...it should not be drug on the ground or rubbing against trees no matter what fabric it's made of....it should be hanging in the air 8-18" off the ground, never touch the ground and be packed away with care, no matter tha fabric. There are many of my comrades in gear construction that are using m90 and m50 and other various light weight fabrics for all sorts of gear that that see a lot heavier use than an UQ should...including all this Cuben tarps out there that get pulled way more than an UQ. I have no issue with m90 or the other similar fabrics being used as a quilt....one of my own personal sets is m90. Nope not going to save a pound or even a half of one...the fabric is just not where the majority of the weight is at in a quilt, it's mostly the insulation, and that does not change no matter the insulation type. Most of a quilts weight is in the down or climashield.

Now to save as much weight as possible if that's the goal first consideration would be how warm of a quilt is truly nescisary. If you need to hit 20 then there will be more weight than if you are good with 40. Less insulation when paired with lighter fabric and lighter quilt suspension (something that becomes an option when using lighter insulation) would add up to several ounces.

That's your nickels worth from the guy that's acctually made thousdands of these things.

Thanks Paul. Appreciate the input and I really do hope to make my purchase with you relatively soon, but I'm going to have to wait a while as previously mentioned. Your input is one I do trust, and will think more about the fabric till I am able to order. I personally not too well versed with suspension, however I do know what I like.
