What Is the Difference Between Brushed and Unbrushed Training Layers?

Brushed layers have raised surface fibers; unbrushed layers retain their original surface.

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 pilling and care behavior.
