While I liked the concept, the vest is bulky if you are on the smaller side. Used a S/M on the Grand and when the muddy water kicked in it was next to impossible to zip-probably not a design flaw, but still. Zipping the vest is a challenge at best since the foam in front ovelaps the zipper making it hard to line up and zip. Once it is zipped it is great-comfortable and feels really beefy and great flotation. If you are a larger person these issues won't matter but if you are smaller I would look to the Orbit Tour maybe or MsFit.
