I have a Heavily used Zpacks 10°F Down bag . 900FP Down

it has holes that are patched with DCF tape and some that are not. however it has not lost much down at all.

it has just been cleaned with Down Tek and does not smell.

the foot box still has 4-5 inches of loft this thing is a beast and I hate to get rid of it but I just bought an enlightened equipment quilt, Original Purchase Price around 400$

Pictures available, and you will be amazing at the loft this thing still has.
