PrimaLoft® Silver [40g] – PrimaLoft® Silver is a high-performance, low-profile synthetic insulation. This insulation is extremely warm, lightweight, water resistant and breathable. One of the major benefits of Primaloft® is that is can be easily compressed into a backpack or bag.

[ak]™ Fit – This jacket’s performance-oriented, articulated fit is loose but not baggy for wearing under a shell and over additional mid-layers. Not quite as streamlined as the [ak] BK Down Insulator, the [ak] Helium Jacket’s fit is true to size and designed to layer under a shell or be worn on its own.
