Description
Technical Warmth Meets Natural Softness.

Designed for the demands of cold-weather running, the Merino and Silk Long Sleeve Base Layer Top offers a premium blend of performance and comfort. This technical garment combines the natural warmth and odor resistance of merino wool with the softness of silk for a luxurious next-to-skin feel. Its close, ergonomic fit traps heat effectively while ensuring rapid moisture wicking and breathability during intense efforts. Finished with flat-locked seams to prevent chafing, it serves as an ideal standalone piece in mild conditions or a reliable foundation when temperatures drop.

• Close fit: Snug warmth with ergonomic precision
• Absorbant
• Naturally antibacterial and odour resistant
• Temperature regulating
• Sweat Wicking: Draws sweat away from the body-fast
• Antibacterial: Wards off odours and keep the garment fresh run after run
• Insulating: This fabric excels at preventing the loss of heat and repelling the cold
• Functional: Designed to optimise on-run utility
• Merino Magic: Luxuriously soft, sweat-wicking, temperature-regulating, and naturally anti-bacterial
• Flat-Locked Seams: Chafe-proof design for ultimate comfort

Materials
