2nd the fleece and synthetics
Here's what I wore this past weekend for rolling practice in 54F water, 35F air temp with the wind blowing.
- short sleeve polypro t-shirt
- long sleeve Helly Hansen polypro/wool shirt
- Reed Chillcheater fleece top
- Reed Chillcheater fleece pants over polypro boxer/briefs
- Fox River synthetic mid weight wicking socks
- Goretex drysuit with stocking feet
- 10mm dive hood
- 5mm dive gloves
- paddle booties
I rolled for an hour without ever feeling chilled or wet. I stopped due to elbow soreness. When I took my shirts off I could ring sweat out of them.
The previous weekend the air temps were in the low 40'sF and I wore all of the above except the HH long sleeve shirt and rolled for 2-1/2 hours and was soaked.
If I'm going out to just paddle, no rolling, I wear all of the above except replace the dive hood with either a fleece hat or balaclava. Sometimes I'll wear Hot Hands pogies instead of the dive gloves and my hands stay very toasty. I always take both just in case. Also take a very warm jacket, hat and mittens to keep warm if you take a break as you'll get cold very quickly.
I also got a neck ring reliever from Kayak Academy when I bought my dry suit. This helps greatly to keep me from overheating. It is made of 3/4" fiberglass reinforced plastic water hose (available from RV shop) and a piece of dowel with one end glued into the hose. Loop it around your neck, then pull the latex neck gasket over the tubing and this vents your dry suit. In the unlikely event of a spill you can nudge the gasket off of the gasket so that you don't get too much (or any) water down the suit. There's a pic on the West coast paddler forum.
I've worn these layers in VA Beach for winter paddling and surfing, winter paddling in the PNW, and now in SW Ohio.
Check out the dive shops in your area. They're a great source. I just picked up the new hood and dive gloves from them.
Good luck and stay warm!
