I am 5' 9" 150lbs. in a new 7mm farmer john with hood, gloves and regular BC (which is a bit bouyant, which is whyi am switching to a BP) in salt water I needed about 20 lbs. Hopefully when I switch to a BP and wings without all the foam insulation I can drop a few pounds. The jacket BC is quite heavy out of the water, and then in the water is buoyant, so I have to carry even more weight.
