Used quilts (Jacks R Better) for 4-5 years and no longer think about it - just use them. Warm, good quality, looking forward to years of use.

GoLite had problems with fill but most reviews I've read indicate they've worked a lot on it... no direct experience with that brand.

If I were to lose my quilts somehow I'd probably replace them with Nunatak quilts, or go to one of the cottage gear places that cater to hammockers, like Warbonnet or Arrowhead. The Warbonnet underquilt I have is excellent quality too.
