Well, I have been using one of Tim's very first quilts since circa 2007(?),well before he became EE, and it is still going strong. Never had any issues with it in over 300 nights (that's a heck of a lot of weekend trips, man). I have used it as a top quilt, under quilt and even a two person top quilt. On the ground, under a hammock or over a hammock, they just plain work. I have also used at least nine versions of his other enLIGHTened Equipment quilts with the same results. Even a few dog quilts. Can't recommend them enough. IMHO, best UL quilt bang for your buck. Full disclosure: sometimes I get to test some of his quilts out and am occasionally a sounding board for new ideas, but I do not work for EE.
My first quilt from Tim (2008):
My son, back from Afghanistan, and I section hiking part of the PCT last year (he used his EE synthetic quilt as a hammock UQ. Marines are notoriously hard on their gear, so it speaks volumes that the thing still looks new.):
Here we have a EE top quilt drying, EE 3/4 under quilt (on the hammock), and an EE dog quilt drying.
Dog quilt (that converts to a doggy parka!)
And just for fun, here's a kilt sporran Tim made for me (whata' guy!).
