After seeing this PFD a couple years ago, it looked uncomfortable and the price was a little high for my liking. I had gone from a full PFD to a inflatable one with no buoyancy unless you activated the CO2 cartridge. With the cold water fishing season about to start I wanted something that was going to be the best of both worlds, with comfort and the option of buoyancy and the extra CO2 cartridge if needed. Considering my first PFD in 2007, I paid $150 for, I figured with the extra features, the Kokatat SeaO2 PFD was worth the extra money. It comes in 2 colors and 2 sizes. I ordered the cobalt and the L/XL which fit perfect with some adjustment for a slightly larger person. Considering there are a lot of XXL guys enjoying the sport, its too bad that Kokatat doesn't offer the larger size. With plans on anchoring in current, one of the reasons I bought this PFD was the nice protected pocket for a knife to be held in. The pocket shuts with a buckle snap which is perfect for securing your knife, and easy access if you needed to pull out the knife quickly. There is a 2nd pocket that zips with room for several items. The high back does not interfere with a higher Kayak Seat which adds to overall comfort. This is the nicest PFD with several features that make it worth the extra dollars
