The Tourmaster Sonora Air 2.0 Jacket does what most other ¾ mesh jackets cannot; it keeps you protected in any condition. The Armor-Link mesh keeps you cool on hot days but when conditions change the Sonora Air 2.0 Jacket continues to work for you. Tourmaster’s Aqua-Therm two-stage waterproof liner can be configured or removed to best match comfort needs.
