If I had two heads, I'd buy another one
The grain of the leather pieces match perfectly, high quality materials and workmanship. I also own a B-3 jacket. The shearling and leather of the hat transition seamlessly to it. It took me a little bit to figure out how to pull the flaps back. (Placing the strap below the adjusting buckle in the back and just above where the shearling comes out of the back works for me.) The fit is perfect, plenty of room for adjustments. With that said, the straps are a functioning part of the hat and should have brass eyelets to give it a more rugged and authentic feel, something I plan on having done. Overall, high quality construction, top quality materials, very satisfied with my purchase!
