There's nothing we don't like about this design from D-Rock.
 
The zipped collar is a fantastic touch with the contrast edging on the collar and sleeves another favourite feature too.
 
These are ideal for both casual and smart - zip them to the top for something a bit more formal but give a glimpse of what's underneath for a more casual look.
 
Stretch fabric - go for the size above if you prefer a looser fit.
 
50.7% cotton, 43.1% polyester, 6.2% elastane.
