Fabric for Synthetic Underquilt

[FLRider]

Thanks everyone. FLRider, I will check into the Argon 67.

Sorry...I missed that this was for an underquilt. While the ARGON is still a wonderful fabric, M50 (from Thru-Hiker) is more wind and water resistant. I'd recommend that for the outer shell of your underquilt if you don't use a tarp with doors, an underquilt protector, or a sock. The wind resistance is worth it. Unfortunately, it's more expensive than ARGON 67.

Hope it helps!

Hey, Sarge. That epsilon looks nice. I think wind resistance and abrasion resistance are valuable qualities. What does "BTY" stand for? Also, is this calendered, hence down-proof? Thanks.

BTY = By The Yard. I doubt that it's calendered as its a MilSpec fabric and the uses for which it is specified does not include down filled products.

HG uses Epsilon as an outer shell for their quilts. I own one. No issues with down coming through on that side. Ripstop by the Roll lists Epsilon as downproof as well.

Just ordered a few yards of the seconds for a top quilt. Hard to beat $3.50/yd for any worthwhile down quilt fabric.

Thanks everybody for the advice. I decided to buy a DD underblanket instead of making a synthetic quilt myself. I like it a lot. Thanks again.
