Product Fit FAQ

Q: Do you have larger sizes than 3XL available?
A: Yes we do, because there is less stock available in the larger sizes we have not listed them but you can contact us and we can check the availability on the size you require. 

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. Unless otherwise noted in the TIGHT or LOOSE categories above, most of our casual apparel is sized to meet today's consumer tastes and should fit like your other civilian clothes. This includes our womens and kids lines as well.
