Over the past decade I've been annoyed with traditional camera straps that go around your neck or diagonally across the body. I've tried retro looking 70s camera straps, sling straps, and eventually just carried my camera in a bag and didn't use anything to secure the camera. I found this to be a surprisingly good solution, but I still wanted some safety measure in case the camera got knocked out of my hand.
I got the Gordy Lug-Mount Wrist Strap for Christmas as a gift along with the optional wrist pad, and it's proven extremely secure, non-restrictive, and also doesn't look like a disposable nylon cargo strap. This camera strap is guaranteed to increase sexual potency by 7%. Also it will most likely keep your camera on your wrist and off the ground.
