Safety orange for turnout during hunting season?

Our horses are currently pastured at the neighbor's down the road. When we get them to our property, they will have access to some wooded areas. Our property borders a huge game reserve which will be full of hunters this fall. Now, in theory there shouldn't be any hunters on our land other than my husband or friends who are aware of our horses. My husband says I don't need to worry about it, but I would like to get some hunter orange on them - at least for modern gun season when there are a lot more hunters out (he won't let me go jogging without hunter orange, even on the road, during the season). I've seen suggestions for things to put on them for trail rides during hunting season, but I need stuff I can put on them while they are loose. I haven't put turnout sheets on them before and they don't seem like a good idea in the woods. Any suggestions - cheaper of course is better, but I don't mind spending money on stuff if it will keep them safe.

You can spray paint the trees around your area with purple I think and put up no trespassing signs. If anyone crosses that border without permission, you can take legal action.

Orange turnout boots?

^See that's what I thought at first, but they would be shooting at the body, and not the legs so, and with underbrush, they wouldn't see the legs very clearly.

Orange breakaway halters?

^I like that!

Could you just buy some hunter orange sheets for the horses?

I found this on another forum...

The Original Equine PROTECTAVEST - Blaze orange horse vests

And if you scroll down to the bottom of the page, there are a few different ideas.

It was something intended to be paired with other things.

Paint them orange? lmao jk. But i but orange collars on my goats... maybe extra super large collars? lol

I dunno if this would work but just a thought.. (person who said paint them orange made me think of it) They do make this paint-ish type stuff that they sell for marking cows. I know it comes in bright bright orange. Maybe that would help? Combined with something else (turnout boots, halter, etc.)? It's pretty inexpensive.
