I've read lots of reviews about fleeces, the cheap ones seem to get as many 5 stars as the expensive ones. A few reviews on The Great Outdoors on line magazine, its free!I've never knowingly used a fleece on my hikes, although I do use a Berhaus full zip cardigan, I don't know if its a fleece?
I have two actual fleeces indoors, one is too warm, one is not bad, but I only use them now and again when I go to the pub. The common feature of both of them is, when there is no wind they work, when its windy they are useless, it just whistles straight through the fabric and I get cold quickly.
I've now solved this problem though, I bought a thin £14.99 windcheater from Decathlon and it works a treat! I just slip it over my fleece and from then on I'm warm as toast.
My preference when hiking is to use a long sleeved bamboo baselayer, a long sleeved shirt, possibly a synthetic jacket (from Alpkit) or my Berghaus cardigan, or both beneath my Decathlon windcheater.
