Merino wool is highly regarded for its ability to naturally regulate body temperature. Its fibres will lock in warmth when the temperature drops but let your body breathe easily if things heat up.
This Moss London jumper in versatile black is made with 50% merino wool. It has a simple crew-neck design, plus textured ribbing around the waistband, cuffs and neck. As the fabric is machine washable, it’s also easy to care for.
Wear it as a standalone piece along with some smart trousers and Derby shoes. The high neckline means you’re unlikely to see a t-shirt underneath should you need an extra layer.
