Filson, Q5, Mule, Cabela’s, Avery, and Orvis that I know of. I only wear blaze orange when the law requires it, when I’m hunting in a party, or during deer season.
The Tenzing BV15 (not BV16, which is their mostly orange upgrade) Upland Vest is a hybrid pack/vest that is sage colored. If you want or need orange it comes with an orange panel that clips over the back. I have used a lot of vests over the decades and consider the Tenzing to be the best for me as I carry a lot of gear and dog stuff (I hunt with as many as 4 at a time). You can find a BV15 if you look around. Including the one I just sold (upgraded to the BV16), there were three sold on Ebay in the last 2 weeks...
