Although I am not familiar with the Ronyn line, I am no stranger to fleece outerwear. This line looks similar to what I have (a Polartec set) and I was going to suggest that you buy fleece with some type of wind stop system in it, but see yours has it. In my case, the wind stop is nothing more than very tight fleece that just helps keep the wind out. I bought mine large enough to layer. So I start wearing it in about 55 degree weather and am still wearing it now when it is 15 degrees out. Under it I will add layers of polyester depending on the temperature. I also add a fleece vest when it gets real cold and windy. The great thing about fleece over wool is its light weight and has a quick drying time. It is also very quiet. Last night while muzzleloading for deer, I lip squeaked a coyote I spotted in to 20 yards....raised on him without any noise whatsoever and then had to drag him out. If the fleece made any noise, he would have booted. I have had mine for about 8 years and still love it.
