How Are Lightweight Running Jackets Designed for Packability?

Packability depends on material bulk, construction, closures, and storage-pocket design.

A layer's specification should identify intended activity, material, measurements, construction, and functional details. Changes to one area can affect fit or processing elsewhere, so document approvals and verify affected features on a production-representative sample before the revised design is released for bulk manufacture. Trial repeated packing without garment damage.
