Is a second hand Patagonia jacket worth it?
Yeah they just had me send it in, I’d go for it if it’s in your budget and use some NikWax tech wash clean/waterproof it when it gets in!

Men's rain jacket that's actually waterproof
Use NikWax tech wash to clean it about as often as you would wash a hoodie (depending on how often you use it) and then when it's wetting out refresh the DWR with the NikWax waterproofing. The tech wash and water proofing are often sold in a 2-pack. I might wash my jacket with tech wash every 3-4 months, depending on usage, and do the waterproofing along with the tech wash but only when it needs it. Source: Used to work at an outdoors store. Biggest complaint about rain jackets from customers was that their jacket "doesn't last" and stops being water proof but they don't do the proper care for them. These are highly technical fabrics that require special care, unfortunately store staff or online descriptions don't really cover that or people don't listen/read.

Men's rain jacket that's actually waterproof
This is not a BIFL suggestion, but some good hardshell pants will also do a better job keeping you dry overall. You can check out gear lists from mountaineering guides like IMG, Alpine Ascents, etc.--they have some good suggestions. r/Mountaineering may be a good resource. For me, personally, my BD Stormline Stretch Jacket and Pants have been superb in torrential rain (outside clearing a flooded culvert for hours) for about five years now. I have some Nixwax Tech Wash and Tech Spray that I use when they get dirty, and will help with longevity. Another tip: if you have a local sail repair, they may be able to mend welded seams or rips/tears. You'll probably never get back to 100 percent waterproof, but it's better than sending synthetic fabrics to the landfill. Or just learn to sew and use gear tape or duct tape. This stuff can really last if you treat it right. Repair is really the only BIFL, IMO.
