Part of our new line of harness accessory pockets that builds upon technology from the backpacking industry. Our Bellows Pocket is now available as a vertical pocket with either a Velcro closure (AC3202), zipper closure (AC3203) or as a horizontal zipper closure (AC3204). Each new pocket includes daisy chain webbing on the external pocket for clipping Z-knives, trauma shears or any tool that you need in easy reach. Cave diving this week? No worries, clip a Z-knife to your pocket. Wreck diving next week? Switch out the Z-knife for a pair of trauma shears or leave them both attached.

You have probably seen daisy chain technology on hiking and mountaineering backpacks. Daisy chains are webbing loops sewn to form a chain. On backpacks, they allow you to attach carabineers for accessories. Dive Rite has taken that concept one step further by developing unique sheaths for our cutting devices that will clip into the daisyloops.

But that's not all. Inside our new pockets resides a 36-inch, looped lanyard to clip off reels, line markers and pocket lights. No more fumbling for the right tools, just pull out the lanyard, select the tool you need, and stuff the loaded lanyard back in the pocket. Lanyard too long? Simply cut and shorten the cord, re-tie the simple knot and cut off the excess. We've seen a few divers out there sporting their own homemade version. Now the rest of us can enjoy the same great idea.
