Anyone out there use climashield apex insulation? Mostly wondering how it compares to down. Weight for weight. Going for a 50 summer quilt and im on the fence between down and apex. It would be nice to here from someone who has tried both. I especially would like to know of its durability in the long haul. Does it lose loft after years?
So basically:
How does it compare to down in warmth to weight?
Does it last long?
