Ordered a large I am 195 and 5'9" and it fits perfect. Nice BCD with plenty of storage and D rings and material feels thick not cheap. Has inegrated weight system and addtional non dumpaable rear weight pockets. Did not hook up to air source and try horn so cannot comment on that. Only negative was the plastic release clips on the integrated weights seemed a little flimsy but they do release quickly when pulled. Might be a good idea to carry a spare in the save a dive bag.
