15.5 lbs buoyancy in a low fitting non-restrictive vest. It wears like a freestyle vest, very comfortable with lost of freedom in the arms and shoulders. The straps adjust every-which-way and it will stay put. The shoulder-straps work off a hidden yoke and this keeps the tension of the two straps even, even though your shoulder are moving. The adjustments for the straps are hidden but easily accessed. The pocket is large and functional, the cover for the knife sheath is great, as is the whistle pouch. The side zipper is held in place by a over-snap...its little things like this that mean a lot to me. Even an extra layer of protection over the spine. It has everything I was looking for in a WW/freestyle/rescue vest.
I am 6 foot 180 lbs and the L-XL is a fine fit for me with room to expand for early spring insulation and room to tighten up when the layers come off. Why 9 out of 10? Price. The Torrent Guide is not cheap. But the good things never are.
