and wander Men's Vent Vest - Light GreyProgressive and idiosyncratic pretty much and wander's MO the Vent Vest is an ingenious mid layer. This is thanks to the fabric, a technical woven polyester ripstop that's air permeable, allowing airflow and keeping you comfortable when you're on the move. The lack of sleeves allow for easy layering, and the two zipped pockets offer ample space for storing essentials. Finished with a ribbed v neck for classic styling.
