The Standard Supply™ Motorcycle Jacket is built with a windproof and water-resistant AR-600™ outershell with a YKK main zipper opening and Speed Zip™ controlled ventilation allowing air to flow free into the jacket when you need it most. Lockdown™ waist adjusters help to create a more versatile fit and shoulder expansion gussets for unrestricted arm movement. To boost protection we've included removable Vault™ CE Level 2 armor for the shoulders and elbows, as well as a CE Level 1 armor in the spine.
