Dripstone weight system

Attach weights directly to the harness without ever re-threading the webbing with this simple system from Dripstone. Weights are held securely by two independent pieces of bungee and a built-in anti-sliding mechanism prevents mounted weights from moving around. Works with any 2-inch webbing, including standard harnesses for sidemount, backmount and rebreathers. Mounts up to 5lb hard lead weights.

This garment compresses like the Weezle Undersuit, which will allow you to pack it away into a small bag. The coat has a front zipper and two hand warmer pockets.

Healthy coral reefs naturally produce sediment -- in fact, that's what atolls are made of.

Are atolls rising to keep up?

Atolls are often only around two meters (6.6 feet) above sea level, but sea levels could rise by more than that by the end of this century, according to prevailing climate models. Four atoll nations -- the Marshall Islands, Tuvalu, Kiribati, and the Maldives, which are together home to more than half a million people -- were the most vulnerable on the planet to climate change but under threat was also those in the Caroline Islands, Cook Islands, Gilbert Islands, Line Islands, Society Islands, Spratly Islands, Seychelles, and Northwestern Hawaiian Islands.
