Replying to Waterproofing spray?

hey so the waterproofing on my jacket is fading so I was thinking about getting some waterproofing spray from REI or somewhere like that.

Anyway most of the bottles I see for sale online say things like "ideal for softshell garments" or things that dont make me think they are for insulated ski jackets.

**So what im asking is, what is the best spray I can pick? will I still have breathability? Also any other things I should know to make the spray the most efficient.**

hope that makes sense, thanks.
