From CP, and I can't find the original email:

Jackets: Jackets are optional during warm weather. At the moment, the only approved optional uniform jacket is the Perrone Leather Jacket.

Base Chief Pilots are not the “uniform police;” however, they have been instructed to make routine inquiries for wildly outrageous uniform decisions.

We are currently in the process of sourcing a new uniform. We still have a good deal of time ahead of us before this occurs. You should continue to order from the current HPI uniform selection.

Many have asked about the Karbon jacket option. Although this is not an official uniform piece, you may elect to wear it, provided the approved epaulets and wings are worn with it. The Velcro name tag should not be worn. We are working on making this an official uniform selection; but do not expect this to happen in the immediate future. I’d like to thank the uniform committee Ryan Pachofsky and Jessica Meyer for their passion for appearance and professionalism. Thanks for serving our pilot group.
