i have a 2010 filo.
while i'm overall quite happy* about its functional side (warm, pops back well after being compressed, i really like the longer-back cut), i noticed a de-colouring issue...
A large patch on the back is now of a much lighter green than the rest.
Not sure if it's a washing problem, i usually wash it once a year with down-specific soap and a gentle program in the washing machine.
Another possible reason is stayed for months in a place where it would get 4 hours of direct sunlight a day : if this de-colours ropes it would also decolour nylon fabrics?
*additional note
i love my filo for dry-weather climbing and dirtbagging but i'm going back to primaloft for my everyday's warm jacket.
Black, so hopefully
stains won't be as visible.
