TOG 24 Arctic Men's Zip NeckGreat layering product. I wore this as a first layer under a thin sweater and a micro light weight fleece, to play tennis in. The fleece quickly came off and I remained warm and comfortable. The "Breathable" nature of the product allowed moisture from my hot shoulder muscles to wick to the surface therefore keeping my shoulder and me dry and comfortably warm.
Putting the micro fleece back on after play, kept me very warm whilst "Warming down". Just the fleece and shell was plenty warm enough under milder conditions.
The recent freezing and windy cold weather has not prevented me from playing tennis once, other than when snowed off, even light rain was not too uncomfortable (though the kit is not waterproof) as I remained warm throughout.
Excellent product at excellent price.
