Thermal tops are the perfect winter accompaniment if you’re planning on spending long periods of time outdoors this winter. Worn close to the skin, they prevent cold air from circulating under your clothing and in-turn helps you to feel warmer. Underlayers are popular with fans of winter sports or any outdoor sport in winter.

Why not pair your thermal top up with a pair of men’s thermal leggings to give your legs the same level of protection.
