No, a simpler model I got about seven years ago. It's just three foam slabs: one on the back, and two on the front with pockets. It just has straps on the sides, so it's very open for arm movements, which is more important for single than double blading because of off-side and back stroke contortions. Sometimes simpler is better for canoeing.
Thinking back over about 35 years, but not counting the horse collars I had for my kids and wife, I've had seven life jackets.
Two were the long kind with lots of thin trapezoidal tubes with waist ties and a fold-up bottom for kayakers. One of those had a pocket. They were popular but had small arm holes even when I was skinny.
For most of my whitewater career I used a Charlie Waldbridge designed Extrasport Hi-Float, which was also a fold up with waist ties. I replaced the waist ties with two prusik lines clipped together with two carabiners for z-drag rescues.
Then I got a really GAS-y short-waisted whitewater rescue vest from Stolquist. It has lots of doodads including a rescue belt, a tow line, and a rope bag that affixes to a pocket on the back.
This was all in the 80's and early 90's.
When I got into sea kayaking in 96 I bought a Lotus Lola. I was able to affix the Stolhlquist belt, tow line and rope bag onto it, and still use it for whitewater.
In 2005 I got sick of the weight had hotness of the all of the above and got the SeaO2, and then the MTI as an all-person spare.
I used to worship at the altar of always wearing a life jacket, even in one foot of water in the summer. But now that I'm statistically convinced I will die of something other than drowning in flat water, I'm more and more enjoying the literal freedom not wearing. I still always bring one, and maybe my cushions too, and wear it on moving and open water.
Bill Mason was frequently shown kneeling on his flat slab vest in his wood/canvas Chestnuts, so he got double duty out of it as a kneeling pad. Another factor is to get a type that can open up well to be a sitting cushion on rocky shores, muddy banks and snow covered lunch spots. The long-waisted ones were better for this.
Fat Elmo says that old foam life jackets lose their buoyancy and don't float him any more. I haven't tested any of mine in more than ten years and probably should do so. Pretty dumb to wear the klutzy things only to sink anyway. I do know my SeaO2 air bladders still work, as I did blow them up once last year.
