This has typical retail price of £50 and I know some people on here will vote cold due to the £5 membership scheme. It's made form Australian Merino wool (65%) so it's soft, warm feeling and when wet, odour resistant
So Why do I think this is hot?
Well in fact Cotsworld Outdoor sell the same item for £48.(http://www.cotswoldoutdoor.com/rab-mens-meco-120-long-sleeve-tee-19110444?id_colour=107)
The next best price I could find was at WebTogs where they have a 10% off code but that's £38.00 before discount. (https://www.webtogs.com/en-UK/Rab-Long-Sleeve-MeCo-120-Mens-Baselayer/31182wmp.htm?colour=Maya)
