Outdoor gear patters Sewing Machines Parts and Sales in Los Angeles

Hey all,
Been lurking on this sub for a minute but now find myself in need of some help. I have been wanting to make myself some outdoor gear, namely a down jacket/vest. I am having a really hard time finding patterns for either project. I also posted this up in r/myog but only got links for $134 kits. If I wanted to spend that much money I’d just buy the thing. Was hoping someone could come through with some help here. Thanks!
