A multi colored horizontal striped polo neck sweater and olive cargo pants are must-have menswear must-haves if you're picking out an off-duty wardrobe that matches up to the highest sartorial standards. A pair of slip-on sneakers will be the ideal complement to your ensemble. As the weather starts to get warmer, it's time to shed those heavy winter layers and choose something lighter, like this look here. A reliable option combo proper for 40-something gents who prefer casual clothing.
