if the jackets kept its down, and is still in otherwise good order i'd probably take to the drycleaners, as they usually offer a repair service. however, the quality of the work will be a complete unknown. will they use a downproof patch etc?????
first though, id try the original makers to see if they offer repairs. PHD offer a repair service for their product range. im sure some others will to.
to do it yourself might be tricky with a needle and thread and probably leave the jacket loosing down through small gaps.
