I like the Game Hide, button down, long sleeve with the orange shoulder patch. Wrinkle free and tough. And not all that expensive.
I know thisis a shirt topic but 15 miles!!! I get your probably chasing some ranging pointers but still. I run a lab and don't rarely go 5mi on a bad day. I can't even imagine being on such pheasantless grounds me and Benny had to go that far to find a couple.A typical day pheasant hunting would have me walking 10-15 miles and anything with buttons seems to restrict movement and not breathe well.
And boy do they last. The colors never seem to fade. I have 3 and have known the secret for years. I mainly only wear them deer hunting. I don't want them to wear out!The best all round shirt for hunting (upland, big game, etc.) that I've found isn't made any more. But it's a Worsterlon shirt from Cabelas. I've had 6 of them over the past 30+ years. They are 100% polyester but yet warm like wool and the dry very fast. They wash up great and are ready to wear without a wrinkle right out of the dryer. I've only read glowing reviews about these shirts over the years and have no idea why the manufacturer ceased production. I just did a Google for Worsterlon shirts and it turned up nothing. I think Gander use to have some also. I still have 4 of them hanging in the closet. They are a great looking shirt that you can wear in the field or casual dress.
Finally ordered a blaze shirt from LL Bean...even though it has BROWN buttons.I have an old Codet polyester blaze orange skirt. Bought it for deer hunting, but it gets used every year for bird hunting. It's time for another but I can't seem to locate one on the internet.
