I'd only used a dry suit a couple of times before purchasing this one. I'm 5'6" and 160 lbs and the medium fits perfectly. I used it January 28th to paddle 2 miles up the river and back. Paddling upstream usually heats me up and I was wearing three layered bottoms and two layered tops. I was never either overheated nor cold. This dry suit along with the Kozee gloves and Scout boots exceeded my expectations for a winter paddle!
An excellent choice for the beginning or occasional boater, the Kokatat Hydrus 3.0 Swift Entry Dry Suit will keep you comfortably dry all day. Hydrus 3.0 is our proprietary waterproof breathable three-layer fabric designed to keep paddlers completely dry in extreme conditions. The super tough nylon woven outer layer provides long lasting abrasion protection and features a durable water repellent (DWR) coating which repels water. The mid-layer utilizes a polyurethane micro-porous coating, allowing water vapor to transfer from the inner layer to the outer. The soft, knit polyester inner layer is engineered to help manage moisture, moving it from the inside out. The result is an exceptionally waterproof, breathable alternative that stays dry and comfortable. Hydrus 3.0 garments are backed by Kokatat?s limited lifetime warranty against defects in materials and workmanship.
