I'll start by saying I'm not affiliated in any way with this company nor have a I purchased, seen in person, or even handled one of their products. However I came across these guys on another forum and thought I'd share.
They custom build 3-layer waterproof breathable jackets. You can customize all sorts of aspects of the jackets from colors, to zippers, to custom chest, shoulder, and sleeve sizes. Fully seam taped and prices ranging from $200-400.
Definitely worth checking out if you're in the market for a waterproof shell.
Would love to hear some feedback if anyone here has used them.
