They say all runners need a foundation, which is why we appreciate our Merino and Silk Base Layers more than most.

Engineered to get runners through the all but deepest winter in comfort, this is a staple short-sleeve that allies the comfort of silk with the natural attributes of merino – quick-drying, moisture-wicking, warm even when wet, and temperature-regulating – making it ideal for high-sweat activities, like ours. As the natural fibres work best next to skin, we’ve cut this short-sleeve with a close fit and added flat-locked seams to eliminate chafing.

Layer it under a jacket or gilet on cooler days, or on its own in fresh weather for a thermal touch.

Naturally antibacterial, it’ll stay fresh, run after run.
