Right now I am running a 1080 vest, one of their 3 series to be exact. I does not hold any water, super light however next to zero buoyancy. Overall the comfort is awesome, flexibility is awesome, but still no buoyancy. So basically safety factor is low, comfort is high. Price is crazy cheap.
My all time favorite vest is the Oniell Outlaw. Similar comfort to my 1080 but with a touch more float. My last one lasted 10 years (actually I sold it so it wasn't really worn out). This will be my next vest. I like my 1080 but it's no outlaw.
