Thought I would do a quick review on these sunnies I bought for windsurfing which are called Surge from Lip Sunglasses. These are the first ones I have used that actually do what they say. They don't fog, water beads off them and they actually stay clear. Probably similar to the Oakley water jacket but less than half the price. They seem to be fairly high quality too. Good value for money at less than $150 including express postage from Europe. Took about 10 days or less to get here.
