Best Use: Hot Weather This hot-weather hybrid hoodie is spec’d with two all-new fabrics for tailored performance. Across the chest, hood, and tops of arms, AirMatrix Technology woven fabric provides maximum breathability with micro-openings.

Both fabrics wick sweat and dry quickly to keep you feeling dry.Leveraging an antimicrobial odor resistant treatment, a UPF 40+ sun protection rating, and a ventilation enhancing loose fit, this hoodie is ideal for keeping you comfortable and protected during long periods of sun exposure.
