Hazard 4 sells a camera bag that you can buy a harness for and make it into a chest pack. Plus it's covered in molle so you can add whatever pouches for lenses and what not on the sides and front.
Esee Knives are top knotch. I have the Esee 4 and I also have and Izula II. The Izula II is a great knife for field dressing, but the only downside I have found is that the micarta handles do absorb liquids. Also Esee's warranty is superb, if you break it the'll replace it. I have beat the sh*t...
