Joseph S.wrote a review of Kokatat TROPOS Helix Dry Top - Men's on May 11, 2010
This is my second Kokatat drytop, and after 5 trips so far this season it's kept me bone dry. During the colder early season runs I normally wear a paddling fleece underneath my drytop. Each time the fleece and my body has come out of my boat bone dry. The neck gasket was TIGHT when I got mine, I stretched it a few nights using a paint can and trimmed two ribs off of it. Now it is snug and no longer choking the crap outta me. Remember to keep the gaskets fairly tight otherwise you will lose the watertight seals.
Fits true to size, generous cut in the shoulders allows full range of motion during paddle strokes without feeing restricted. I was also able to layer with a fleece without giving up any comfort or range of motion. I'll update my review later this year when the water runs out here in Colorado.
