Good video camera for outdoorsy person?

I'm really looking for a good video camera that can handle the outdoors. Waterproof is a must. Also, optical zoom is a must. And, it must be able to fit into a coat pocket. I don't want to lug around a big camera. I'm hiking, so weight is an issue too.

The one camera that has caught my attention is the Nikon AW100. Has some nice features, but hasn't gotten the best reviews. However, most of that was geared towards interface or for the pictures, not video. I wouldn't mind a point n shoot with video capabilities, but I would use the video function more than the picture stuff. I use a DSLR for my pictures.

Anyway, just weighing my options here. Anybody know of any video cameras that would be good to fit here?

I wouldn't like anything more expensive than the AW100. That is as high as I'll go. I'm not even sure if the AW100 is worth its price tag.

The Panasonic TS3 is cheaper than the AW100.It's TIPA's best rugged camera for 2011. And the HD video is the best compared to all other waterproof cameras in the market now.

Used to be as expensive as the AW100. But it's around $270 now

I think sony is the best brand for a camera gadget. It's pretty amazing
