The go-to-t-shirt for warm weather hiking, the Regatta Men's Breakbar II T-Shirt is designed to keep cool and active. Constructed with Isovent honeycomb polyester, the T-shirt is lightweight and gently moves moisture from the surface of the skin for rapid evaporation and increased cooling. Mesh inserts aid airflow and breathability, and a zip neck design allows for a personalised, ventilated fit.
