Is this jacket warm enough for winter?

It is a cotton blend shell meant for layering in cooler weather. It has no insulation or liner, so it suits fall and mild winter days over a sweater, not deep cold.

No. The cotton blend resists light wear but has no waterproof coating or membrane. It is fine for dry outdoor use and light drizzle, not sustained rain.

Are the patches removable?

The embroidered name and U.S. Air Force patches are sewn onto the chest pockets and sleeves. They are part of the design, not removable velcro patches.

It is described as a classic fit with long sleeves and a fold-over collar. That usually leaves room for a layer underneath; slim builds may find it roomy.

What pockets does it have?

It has multiple patch pockets on the front, including the chest pockets that carry the insignia. They are button-front patch pockets, not zipped or hidden ones.

How does it compare with a surplus military jacket?

It copies the field-jacket look with pre-sewn insignia and a cotton blend shell. A surplus jacket is usually heavier and plainer, without decorative patches.
