Sizing and Fit Guide

When deciding what size to purchase there are a few things to keep in mind. First, take a look at our Size Chat to see what we recommend based on your weight and measurements. Second, our jackets come in three different types of fits. Each item on our site has been classified as one of these and you should use that to size up or down if necessary.

Sizing and Fit FAQ

Q: Why do you make flight jackets in a tight fit? Why not just make your coats bigger?
A: For over 50 years, we've proudly built our legacy on manufacturing rugged outerwear for the U.S. Military. The Dept. of Defense has very strict requirements regarding pilot jackets and has traditionally mandated a tighter fitting garment for use inside the cozy confines of the cockpit. We continue to construct these jackets 'just like the old days' by using similar materials and manufacturing specifications. These are the 'real deal' Alpha jackets and not the imposters you see in many surplus outlets.

Q: Why do I need to order a size X-large when I wear a size large in everything else?
A: Because we remain true to our heritage when producing our authentic flight jackets, this unfortunately can create some confusion amongst our shoppers. The size coat they normally purchase does not match up with our general sizing guidelines. As a general rule, we recommend customers to 'size up' when purchasing one of our flight jackets.

Q: If I like to wear layers under my flight jacket or like a 'baggier' fit, should I order the next size up?
A: Ordering a size larger is definitely recommended in our authentic flight jackets. A majority of our flight jacket exchanges come from customers wanting to 'size up' and order a larger size jacket.

Q: Are your field coats really that big?
A: A vast majority of consumer exchanges on our field coats are for the next size SMALLER. That is why we recommend 'sizing down' on most field coat sizes here, especially if you are borderline between sizes on the chart above.

Q: Is the M-65 Field Coat the real thing? Why is it so big? Is the M-65 really that tough and rugged?
A: The M-65's reputation as the workhouse of the battlefield is well-deserved. The M-65 was designed to fit over top of body armor and was used extensively in jungles of Vietnam to protect our troops. Even today, the M-65 remains quite popular with military enthusiasts and outdoorsmen looking for seriously rugged outerwear that can protect against harsh climate conditions and the elements.

Q: Do all of Alpha jacket and coat sizes stray from conventional civilian sizing parameters?
A: No, not all of them. On each jacket or coat page you will find one of the icons above that tells you the type of fit. If it is a standard fit it should fit like your other civilian clothes. This includes our womens and kids lines as well.

Q. I am afraid of being stuck with a coat that does not fit. Does Alpha offer an easy exchange process?
A: Yes, our customer-friendly exchange program is designed to quickly and easily get you the right-sized item should you ever need to change it. Plus, if you live within the U.S. Continental 48 States, we'll even pay for shipping (on your exchanged item and the replacement shipment back to you). See our Product Returns section for more details.
