The ID RBK Training Quarter Zip arrives in Black, a slim-fit training layer built for sessions that start cold and heat up quickly. The quarter zip gives you immediate ventilation control without requiring a full layer change mid-session. Mesh panels run through the construction, adding airflow to the areas that work hardest during sustained high-intensity effort. Reflective heat transfer logos sit across the build, with reflective tape at the back body to maintain visibility during low-light outdoor sessions. The slim fit keeps the layer close to the body, working effectively as a standalone training top and as a mid-layer under a windbreaker or jacket. The quarter zip collar also lets you regulate temperature precisely at the neck as conditions change through the session. Pair with training shorts or fitted jogger pants for a complete slim-line training look in Black.
