When the thermometer drops, our range of long sleeve jumpers for men will have your back. Up your layering game with our men's long sleeve cardigans and knitwear. On the hunt for office-worthy woollies? Our crew neck styles are a good place to start. Their rounded neckline makes them easy to layer over smart shirts. Look out for thinner, smoother knits that combine plenty of comfort with a lightweight wear. In the mood for something a little different, yet still as smart? Our zip-up turtlenecks are an excellent alternative to a traditional long sleeve men's jumper. They're fitted enough to be worn on their own, or you can add a T-shirt underneath for extra warmth. If you're after a long sleeve style with a relaxed vibe, a classic polo neck is a timeless smart-casual choice. Smoothly knitted textures create a sleek, smooth outline. Or you can pick out a chunky, unstructured piece and revel in that laid-back weekend feel. When it comes to colour, every gent needs a stock of go-with-anything plains in his long sleeve jumper collection. Whether you're stocking up on jumpers or picking out a men's long sleeve cardigan, blacks, greys and navy tones are the most versatile options. If you're looking for something a little bolder, take a gander at our bright primary shades. Or show off your softer side with a pastel hue. An intricately knitted pattern or neat rib-stitch adds extra textural interest to your outfit. Complex cabled designs in heavyweight wool give a casual off-duty vibe, while finer yarns and subtle motifs are ideal for office dressing. Keep an eye out for ribbed trims, that help your knitwear move with you and hold onto its shape.
