This lightweight polyester shirt is ribbed and very elastic, especially across its width, so it stretches comfortably around your body for a close fit.
It's excellent at channelling moisture away from your skin and adds a good amount of insulation when required. Plus, it doesn't hang on to odours after washing like some base layers can. There are no labels to cause discomfort while the only seams are in the raglan shoulders and they're flat-stitched. A high-necked long sleeve is also available for just £2 more.
