Best in cool to mild conditions, the Thermocool from Altura is the Yorkshire-based brand’s top-of-the-range options.

It’s made from a synthetic mix of 73 per cent polyester, 22 per cent polyamide and five per cent elastane, in what is a soft, comfortable base layer. The fabric is heavier than a mesh material and is best for cool to mild conditions, rather than the hottest conditions, but that means it’s a versatile option which should get plenty of use through the year in the UK.

Review: Altura Thermocool short sleeve base layer

The fit is super-stretchy and sits close to the body to boost its wicking credentials, and when the fabric does get damp then it’s fast-drying. Finally, an anti-bacterial ‘Bodyfresh’ yarn keeps things relatively fresh for longer.
