Alpinestars Radium V2 Denim Motorcycle Textile Pants

The Radium V2 Denim Pants feature a refined modern cut with a regular tapered leg and elevated finishing and trim details. The Radium V2 Denim pant is a premium five-pocket sport and urban riding jean constructed from stretch Cordura® material technology with a cotton polyester and polyamide blend with 2% elastane. The pants have aramidic reinforcements on the knees, and polyamide lining on the hips for excellent Double-A rated abrasion resistance. Internally, for impact protection there is adjustable Level 1 rated Nucleon Flex Plus armor, which sits in a 3-position adjustable knee pocket with color-coded stitching to differentiate the individual pockets which measure in 3 cm increments to dial in the perfect rider fit. The denim material of the Radium V2 tech riding pants has a thermal regulation treatment to maximize breathability and ventilation comfort on warmer days.

How to measure your height:

1 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.

2 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.

3 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.

4 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.

SUPERIOR

Pantalón muy cómodo. Nada homguero; ceñido pero nada exagerado. Tiene un punto elástico adecuado, nada rígido. Por dentro se siente suave lo que aporta más sensación de comodidad. En la moto se siente pegado y con libertad de movimientos, lo cual favorece su comodidad conduciendo y tumbando en curvas (moto RR)

Excellent

I use these for commuting to work and for local rides. They are comfortable and true to size. Didn’t need to size up or down. I wore them while at the Isle of Man TT for around town. Casual looking Jean with good protection
