Smartwool NTS Mid 250 Zip (2014)

At the top end of the price range, we find this: supremely comfortable merino wool, fitted but not clingy, a completely natural thermostat and easy to wash too. And as a bonus, it's muted enough to hide all its technical brilliance in a top that looks profoundly ‘normal’. I wore it on four separate trips without washing it, and it stayed odour-free and moisture-free throughout. It also has a long back to keep draughts at bay. It’s the heaviest top here, and it’s perhaps a bit too thick for anything other than very cold days – for more year-round usage you might like to try its thinner brother the NTS Light (NTS, by the way, stands for Next To Skin). But if you’re planning on heading anywhere chilly over winter – be it the top of a coastal cliff path or a snowy Highland summit – this is the one to choose. It’s the sheer comfort and absolute reliability that justifies the price tag here.
