Part of the pro is the con. When you adjust this sling as tight as it will go with your set up there aren't any straps hanging to get snagged. However, because the strap is contained it will only adjust half the length of the forward strap. When you need to put your weapon behind you to climb or need dexterity of both hands it doesn't snug tight up to your body. That's not a flaw with the sling itself, but a trade off if you want your unused strap to be contained so it can't get caught on your gear. I work around it's limited adjustability (it does have quite a bit more adjustment than other contained slings I've used). All that said, I really like this sling. I've used it on my weapon for over a year now and it has held up very well. It's my favorite sling to date.
Pros: Straps not hanging, adjusts quickly
Cons: not a very large range of adjustment
