Before You Decide

Confirm the medium size and charcoal colour are the variant you want. Check the 50% cotton and 50% polyester fabric blend against your preference, and make sure machine washing at 40°C works for your routine.

Check the Fit in Layers

When planning an outfit for cold weather, try the bottoms beneath the trousers you expect to wear. Check that the combined layers leave room to sit and bend, and that the fabric does not bunch uncomfortably around the waist or ankles.
