I'm not sure on the effectiveness of most fishing tackle brand winter clothing, as most are not outdoor specialists in the clothing range. I prefer army surplus, hunting or shooting clothing.
My cold weather clothing is from army surplus, and Hoggs of Fife, along with Merino wool socks.
Top half is usually t-shirt, Norgie or UBAC with a standard fleece on top, and a Hoggs Strathmoor jacket on top, (look at current outdoor shooting or hunting jackets), or a DPM wind and water resistant smock on top.
Bottom half is combats with Hoggs overtrousers, and the Merino under my combat boots.
For the neck I do have either a snood or my shemagh.
That is cold winter wear!
