Go hit the trail with a fun print and a relaxed vibe with the Summit Button-Up, but not at the expense of technical performance. This shirt is constructed from highly breathable Transfer Mesh fabric to keep you cooler, dryer and comfortable in the heat. Mountain bike-friendly features include shoulder seams strategically positioned for comfort when wearing a hydration pack, and stretch-woven polyester sleeves to improve airflow. GoFresh™ tech fights the funk and allows you to relax post ride without smelling like you just crushed 20 miles.
