A BP with 80 pounds of tanks on it might not be comfortable for a hike but we are not hiking, we are diving. I might note that a vest or back inflate integrated cumberbund BC will not be comfortable either with 80 pounds since it could not possibly even hold 80 pounds to begin with. The facts are that in the water a BP/wing is far more comfortable than loosely fitted generic vest/back inflate --to me---others may vary. I hate all the bulk of a vest or back inflate and all that padding. N
