Alpinestars SMX Air Perforated Motorcycle Textile Jacket

The SMX Air sport jacket features a main chassis of tech mesh on the rider's abdomen, back and inner arms, paired with 450D polyfabric reinforcements on the outer arms and shoulders. The SMX Air also features perforated 450D polyfabric in the upper chest area for excellent air circulation during the warm summer months. An extended polyamide stretch material is incorporated at the back, shoulders and sides of the rider, and a high-density stretch material is incorporated at the upper back. The stretch material provides a custom fit and a high degree of freedom of movement, and offers the perfect amount of stretch for use with the Tech-Air® 5 Airbag System. Tuned for optimal ventilation, the SMX Air Jacket features a removable windbreak liner that reduces airflow when not needed, providing optimal climate comfort and versatility.

How to measure your height:

1 Shoulder width

Measure your shoulder width across your back from the outer edge of one shoulder to the outer edge of the other. Stand upright and let your arms hang relaxed at your sides. Guide the tape measure from shoulder point to shoulder point across the upper back and make sure it does not slip.

2 Chest circumference

Measure your chest circumference at the fullest part of your chest. Run the tape measure horizontally around your upper body under your arms. Make sure the tape stays level and breathe naturally without puffing out your chest.

3 Waist

Measure your waist at the narrowest part of your torso, usually just above your belly button. Stand upright and keep breathing normally while you place the tape measure horizontally around your body. Make sure the tape is not digging in but also not too loose, so you get a realistic measurement.

4 Hips

Measure your hips at the widest part of your buttocks. Stand upright with your feet about hip-width apart and place the tape measure horizontally around your body. Make sure the tape stays at the same height all the way around and does not slip up or down.

5 Arm length

Measure your arm length from the outer shoulder point to your wrist. Let your arm hang naturally and relaxed at your side. Run the tape measure along the outside of your arm down to the wrist.

6 Inseam

Measure your inseam from the crotch down along the inside of your leg to the sole of your foot. Stand upright, ideally without shoes and with your legs slightly apart. Run the tape measure straight down and make sure it does not slip.

7 Outseam

Measure the outside leg length from your hip down the outside of your leg to the sole of your foot. Stand upright and barefoot with your legs naturally straight. Place the tape measure at the side of your hip and run it straight down to the sole. Make sure it stays close to your body and does not slip.

8 Thigh

Measure your thigh at the fullest part. Wrap the tape loosely around your leg without pulling it tight. For an accurate result, stand relaxed and distribute your weight evenly on both legs.
