*THRIFTED* Adidas Waterproof Rain 3-in-1 Jacket

System: This is an interchangeable system where the inner jacket zips directly into the outer shell.

Outer Layer (Right): A waterproof/windproof hard shell (Red). You correctly identified it as likely being GORE-TEXor Climaproof (Adidas's proprietary weather tech). It features a storm hood and technical zippers.

Inner Layer (Left): An insulated liner jacket (Red with Yellow zipper). Unlike cheap fleece liners, this appears to be synthetic insulation (likely Primaloft or similar), which is lightweight but very warm. The yellow zipper acts as the connection point to the outer shell.

Era: The specific red/yellow colorway and logo placement suggest this is a slightly older "Adidas Outdoor" model (pre-2020), which often used these bold contrast colors.
