H2O Ninja: Fullface GoPro snorkelling mask
Ever so often something really cool comes along that surprises me with its sheer brilliance like this snorkelling mask that lets you snorkel longer while breathing easily through your mouth and nose just like on land and at the same time has a GoPro mount built into it. It is said to increase snorkel time from 10-15 minutes up to 20-30 minutes. The full face design also eliminateds the need for a mouthpiece and reduces fogging. It comes in 3 different colours too. A quick look online also exposed many china made copies that don't work as well too.
