A quality cycling base layer is the most underrated piece of kit you own. Attaquer merino cycling base layers regulate temperature in both directions — insulating when it's cold, wicking and ventilating when the effort climbs. Natural merino wool manages moisture without synthetic odour buildup, making it the practical choice for back-to-back training days and multi-day riding. The mesh construction maximises airflow while maintaining warmth at rest, creating a microclimate between your skin and your jersey that works regardless of conditions.

Wear under your men's cycling jersey or women's cycling jersey for full thermal control across variable conditions. The long-sleeve base layer pairs particularly well with a cycling arm warmers setup — giving you layering flexibility across the full range of Australian riding seasons. Merino cycling undergarments work hardest when the weather is at its worst. They're the invisible foundation of a properly built kit system, and once you ride with one, you won't ride without it.
