Our new versatile mac is made from a finely woven, cotton blend fabric in dark navy, with a contrasting khaki collar stand. The showerproof fabric, which will also cut out the wind, is lightweight with a matt finish. The minimalist style has clean lines with concealed pockets vented in the side panel seam, a concealed placket covering a zip and four press studs and a single rear vent. Inside, there are two jetted breast pockets and a full lining, which provides some warmth. The mac has a straight fit and is cut at a shorter length, which gives the versatility to double up as a jacket in the cooler months.
