I thought it was a Burning Man flashback, but then realized this SCUBA mask is more than just a trippy Playa costume. The Hydrooptix Mega 4.5DD has a Double-Dome lens designed by the same engineers that NASA hired to fix the Hubble telescope. The mask not only offers a panoramic view five times larger than you get with a flat mask, but is made from the same polycarbonate material used in bulletproof glass. Finally, a way to hunt those Kalashnikov sharks I saw on the Discovery Channel. $199.
