Sling Pack with auxilary anchor strap?

[Terry Green]

I hear ya on the water bottles.... I smash them to where the water is at the rim and screw the top back on so there is no sloshing sound while I'm stalking. Same with a bladder.

I have used this Duluth Trading sling pack for approx. 10 years now and it is still going strong.
It has become very supple and quiet and holds a surprisingly large amount of stuff.
They also come in a few different colors, mine is green.
