Nike SB Bowler Button Up Shirt. Over the line! This Nike SB woven top draws inspiration from classic bowling shirts—with a bold, all-over print. It's made from stretchy, lightweight fabric and cut with extra room through the chest and body for easy movement. Sweat-wicking fabric helps you stay dry on and off your board—or in the lane, staring down that spare. Lightweight woven fabric has a soft feel with a bit of elastane for stretch. Button closure keeps the look versatile, so you can wear it how you want. Designed to feel roomy through the chest and body for easy movement and layering. Nike SB woven flag label on the chest pocket. Spread collar. 86% Polyester 14% Elastane. Machine wash. Imported.
