The Icon is a great, stylish jersey with the added bonus that you'll have to work really hard to try and make it smell! The use of lots of merino wool in the fabric blend is what gives the jersey its stink-beating properties. Mons Royal's Merino Air-Con blend perfectly balances warmth, odour protection, durability and breathability. The inclusion of some synthetic fibres makes the fabric tougher and aids in wicking without stopping the merino from doing its thing. So, if you don't want to worry about carrying a backup jacket in the shoulder season, opt for the one-layer solution with the Icon Jersey.
