GGG pack designs are a byproduct of lots of caving with other packs and being disappointed by their performance. GGG packs are made from either 18 oz. PVC-coated polyester or double thick Cordura (11 oz. lined with PVC-coated 8 oz. pack cloth). They come in two basic styles: side loading or top loading. The top loading packs close much like a river bag does: the two sides Velcro together, the top rolls down, and the ends clip together with a side release buckle. The side loading packs have a zipper that runs the whole length of the pack to allow complete access to the contents of the pack. The zipper is a #10 tooth-in-box zipper (the kind that closes wetsuits) that is protected by a flap of web. The medium and large packs have compression straps so that you'll never have a case of "limp pack syndrome." All the packs have very large drain holes so there's no waiting around for the water to empty out.
This pack is great for longer day trips where you might be carrying rigging gear or extra clothes and food. It has adjustable 1.75" web shoulder straps, tether loop and a carrying handle on the side of the bag. Abrasion skirt and small inside pocket. 9"dx24"h, 1525 cu. in. Cordura Version.
