Great sling - Metolius Multi-Loop Double-D Gear Sling

This gear sling is really well designed! It can be worn on either shoulder and has plenty of loops to hang your gear on, keeping them all easy to reach! The auxiliary strap can be reversed to adjust length in the front or back.
The only detriment with this sling is the auxiliary strap is really flexible, which makes it a little more difficult to rack/unrack when it's almost empty, so plan your desperate placements accordingly.
