Engineering a leather motorcycle jacket seems simple, but it gets complicated to strike the optimal balance of protection, versatility, and style. It’s almost impossible to beat the abrasion resistance and visual appeal of leather, although it’s often compromised by unsuitability for hot or wet weather.

The Gunner is Highway 21’s top-line jacket and is designed to eliminate the compromises inherent in leather apparel. It’s built from sturdy leather but is endowed with a 12-point ventilation system to keep you cool and a removable Hydraguard liner to keep you warm and dry.

The Gunner proved to be a versatile leather jacket that’s suitable for most weather conditions. Also seen here are Highway 21 Blockhouse jeans and Journeyman boots.

Naturally, the Gunner is available in black, but I opted for the Vintage Gunmetal version that isn’t so typical. It’s constructed of 1.0-1.1mm cowhide and features removable CE Level 1 armor for shoulders and elbows, with the latter reinforced by leather patches. A foam back pad is included and can be upgraded to CE levels of protection by swapping in optional Fly Racing Barricade armor.

The Gunner’s styling is a cross between a biker aesthetic and cafe-racer panache. It has a low-cut band collar topping a two-way YKK main zipper with a handy leather zip pull. Four snaps on each side help adjust for a non-baggy fit, augmented by a pair of accordion stretch panels at the waist. Shoulder gussets provide arms additional freedom of movement, and reflective piping across the shoulder-blade area aids nighttime conspicuity.

We tested the Vintage Gunmetal version of the Highway 21 Gunner, but it’s also available in a classic black model.

High temperatures are moderated by a healthy array of zippered venting, including intake vents on the chest and biceps, as well as massive armpit vents that stretch from the upper waist area up the ribs and down the arms to the elbows. Zippered exhaust vents span 10 inches down the sides to encourage pass-through airflow. Additionally, the jacket features two-way cuff zippers to reveal forearm vents. With all the vents open, the Gunner flows much more air than typical leather jackets.

Inclement weather is countered by the removable liner, which is quilted on the inner side and backed by a Hydraguard layer claimed to be windproof and waterproof but also breathable.

The Highway 21 Gunner leather motorcycle jacket is constructed from thick leather and includes shoulder and elbow armor for added protection.

The Gunner is equipped with pockets for almost everything. The exterior has zippered hand-warmer pockets, and the chest zippers for ventilation double as another pair of stash zones. Internal storage is provided by deep “Napoleon” pockets on each side of the main zipper, and an interior device pocket doubles as a concealed-carry receptacle. 

Miles on the road with the Gunner were almost completely satisfying. Cold temps were abated by closing the vents and zipping in the liner. The low collar exposes the neck area to the elements, so I wore a neck gaiter to keep that area protected. The jacket kept me dry in a mild rain, but I haven’t yet tested it in a downpour. 

Overall, the Gunner offers appealing versatility and cool style for a modest price. If I had a complaint, it’s that the material doesn’t have the suppleness of “top-grain” leather found in some pricier jackets. Its MSRP starts at $399.95 for sizes S-2XL and goes up to $439.95 for sizes 3XL and 4XL.
