I wear a upland hunting vest I got at Canadian Tire. I like it because of all the pockets and the big game pocket on the back. Wasn't much more than the one you have there.
I recommend a nice quiet one.
$25 or $30 is not too much to pay for a nicer vest
There is a black elastic on each side holding the front and back. Though it is a bit loose so i may have to stitch it up a little to make it wrap around my body better
I havent measured it yet, but it the requirement says "it must be visible from all sides", does that mean it cannot have have a band at the side? I mean when i turn to the side, i can see the orange on my chest and back
