HELP! DOWN JACKET REPAIR

[newmum953]

Hi all. I managed to cut a slash in my down jacket so now there is down coming out of it. Any suggestions on how to repair? The outer is nylon and it looks similar this www.gap.eu/browse/product.do?cid=68138&vid=1&pid=860002 but is black. The outer is nylon. I have heard of repair tape but don't know if this is a good option?

RAB repaired by husbands jacket really well - maybe worth asking their workshop if they take NON RAB items??

Thanks!
