Grundens' most breathable rain shell, the Charter GORE-TEX Jacket keeps us dry, whether we're on a fishing charter, piloting our own boat, or wearing it off the water. The GORE-TEX Paclite Plus membrane is highly breathable and packable while being highly waterproof and windproof--that keeps us comfortably dry as we're fishing the rain bite or eating spray as we speed across the lake to our honey hole. Grundens also ratcheted up the comfort the raglan sleeves for more range of motion when we're casting and a back vent that maximizes airflow for better ventilation and breathability.
