not as breathable as some hiking shells
I have one (in grey) and also the long-sleeve version (red and white). They were both sold at a steep discount on STP, which is why I bought them without really realizing the utility. But I have since discovered that paddling jackets are far superior to wearing a regular rain jacket or shell, because the arm and neck gaskets keep water from running down your sleeves as you lift your arms to take a stroke. They are also cut so that you have plenty of space in the shoulders, which doesn't limit your paddling movements like a regular jacket might.
I mostly use the long sleeve as my primary jacket when I do extended trips in the Everglades, both in my kayak and sometimes for hiking. It serves well as a windbreaker, paddling jacket, jacket for cool days, and even as a rain jacket in the occasional downpour..though I found I needed a rain hat to keep the water from running down my neck through the neoprene gasket. I even slept in it a couple nights because I was chilled in my hammock. They pack down really well too, almost taking up no space. It is a great multi-purpose garment.
The neoprene cuffs are adjustable and the jacket has one zippered external pocket, though I don't find it very useful because I'm usually wearing a PFD that has a large pocket. The seams are all taped. The material is not as breathable as most dedicated hiking shells but still decent. Given the price I paid ($25 each), I give these jackets a high score. You'd be hard pressed to find a splash jacket for under $50 these days.
