Debut Merino Long Sleeve Jersey

Merino-wool take on our best-selling Debut long sleeve, built for colder conditions. Using finest merino fibers for natural thermoregulation, it helps maintain optimal body temperature when the temps drop.

Meet the Debut you reach for when autumn turns crisp and the air bites back. This minimalist, functional jersey blends comfort, performance, and value. We combine two merino-rich fabrics: a heavier knit on the front and back for warmth and protection, and a lighter, micro-perforated knit on the sleeves to boost airflow when the ride gets more intensive. The result is a jersey that breathes when you’re working, insulates when you ease off, and moves naturally with every shift on the bike.

A medium-compression pattern keeps things supportive without restricting motion. A silicone tape at the back hem holds the fit in place, and three spacious rear pockets swallow snacks, gloves, and spares. Reflective branding improves visibility in traffic, rounding out a versatile layer made for real-world autumn miles.
