What Is the Difference Between Softshell and Knitted Activewear Jackets?

Softshell describes a performance fabric system; knitted jackets describe construction more broadly.

Fabric weight alone does not establish warmth, breathability, wind resistance, or durability. Structure, finish, layering, and garment design all contribute, so compare production-intended materials against the relevant use conditions and define the evidence required before making specific performance claims about the finished product. Compare actual layers and verified functions.
