spoke to them this morning. very helpful.
bag will be emptied of down and the shell cleaned. the down is cleaned seperatley (they will do this twice if they think they can revitalise exhausted down). shell is then refilled with cleaned down - cost £35.
if down needs to be replaced it is charged at £20 per 100grms.
looby - jackets are no problem for them, i did ask on your behave. refilling and cleaning anything filled with down is their bussiness.
apart from cleaning other peoples bags they also manufacture their own down bags.
