The HydroSkin shirt is warm by itself on moderately cool days, and makes an ideal mid-weight addition between a thermal inner layer and a windproof outer shell. The perfect addition to your gear bag.

This top is a real problem-solver. It's a full-coverage top that incurs almost no penalty in freedom of movement. If you get very cold, you can wear it under a Neoprene Farmer John (or Jane) for excellent insulation performance and relatively little cost. It's also a great stand-alone top for kayak touring on the ocean or Great Lakes. It provides sun protection and "just in case" warmth, but is still pretty comfortable in the air. If you start to heat up, get it wet and the evaporative cooling will give you some relief. The cut is unisex, but the material is so stretchy that the fit is forgiving. The terry loop lining makes it comfortable and non-clammy against the skin.
