My favorite is a custom field jacket worn by a hero who served in two wars. He gifted it to me and I wore it ever since.
When it started wearing out around the sleeve cuffs, I had a Taylor refurbish it to custom specs. The OD green tight weave cotton was more than perfect for the project. It sheds rain very well and is dressy enough for a Sunday morning or the dense woods of West Virginia. I have looked at all of the brands and wouldn't trade it for any of them, even without the sentimental value. I finished the jacket and on these cold rainy days, it's a welcome reminder of my uncle.
