If you're thinking about making one, I will point out a few things I'd do differently if I make another.
1. I started the opening too far up from the base. You need to draw the arrow a bit too far back to get it out.
2. I would make the upper part longer above the shoulder strap so a very lightweight cover could be placed over the fletching.
3. I would make a detachable cover for the body opening - maybe one that could be rolled up and tied/snapped out of the way when not needed.
Otherwise, I like them a lot. I find it can be worn under the arm, or you can swing it up and wear it like a back quiver.
If you need examples, look at Safari Tuff Arrowmaster quiver. I think they have just about all the bases covered.
