10-28-2026 Overall, a nice merino wool sweater, but it runs very large and the sleeves are also very wide. As a result, it looks a bit sloppy and overly roomy. Next time, I’ll just go back to the merino wool sweaters from Suitable. R.
10-24-2026 As expected, and specifically for men. Ron

06-20-2026 Lovely jumper. I was able to choose from a great colour palette again. Almost all my jumpers are made from merino wool, and it feels really comfortable in both summer and winter. Easy to wash! Henk

What's the difference between a round neck and an O-neck?

A round neck and an O-neck mean the same thing. Both terms refer to a classic neckline that snugly frames the collarbone. Recognizable, timeless, and beloved by many men. Pay attention to the finishing details per brand; some models have a slightly higher neckline.

Note: Do not confuse a round neck with a mock neck (a raised edge) or a turtleneck jumper, which sits much higher and warmer around the neck!

What to wear under a round neck jumper?

It depends on the occasion and the image you want to convey. For a polished look, an shirt is a popular choice. The collar subtly peaks above the jumper. Opt for a plain shirt or a subtle pattern, like checks or stripes. For a casual vibe, a basic T-shirt works great as a comfortable base layer. For extra warmth, you can also choose to wear a thermal shirt or a long sleeve T-shirt.

How do I wear a shirt under a round neck jumper?

Make sure the collar is not too bulky or high. Cutaway and Widespread collars are ideal for this. They stay neatly in place and sit nicely under a jumper. Want to elevate the outfit a bit? You can pair it with a matching tie.

Which colour round neck jumper suits me?

Build a solid foundation with timeless colours like navy blue, charcoal grey, or black. These are perfect for winter and endlessly versatile. For autumn, options like burgundy, dark green, or rust brown are great choices. As summer approaches, opt for lighter shades like light blue, pastel green, and soft greys to keep your outfit fresh and contemporary.
