Halfdays Gwen Jacket

What Our Gearhead® Experts Are Saying:"The fabric is incredibly light, and the UPF protection is a real bonus on exposed trails. The mesh panels help a lot with heat, and being able to pack it into its own pocket makes it perfect for travel or variable weather."Bright days on exposed trails feel more manageable with the Gwen Jacket in the mix. The recycled polyester fabric brings light stretch and UPF 50+ coverage, creating a protective layer that remains soft and breathable during warm-weather movement. Mesh panel inserts increase airflow, helping maintain comfort when the sun hangs high or the pace shifts upward.An adjustable bottom hem fine-tunes the fit, and the entire jacket packs neatly into the back pocket for easy stowing when conditions change. The design stays streamlined and flexible, supporting everything from quick morning trail laps to full afternoons outdoors. With a balance of packability, coverage, and ventilation, this jacket steps into sunny forecasts with confidence.
