Alpinestars Racer Air Lone Pants

Perforated Racer pants for summer motos

The Racer Air Lone Pants are the warm-weather version of Alpinestars' Racer Lone pants: a lightweight 600D polyfabric chassis with extensive perforation, stretch ripstop inserts in the flex zones and Stretchnet down the back of the lower legs, so the air gets through when the track is baking. The seat and knees are reinforced, the inner knees are goat leather for heat and abrasion against the bike, and the graphic is dyed into the material, so it holds its colour through repeated riding and washing. A mesh liner is included.

Sizing and fit

Waist sizes 28 to 40, in a single colourway. Sport-cut race fit, close through the leg; size up if you're between sizes or wearing knee guards. SX2 auto-lock magnetic buckle with adjustable waist closure, plus a silicone inner waistline to keep them in place.

Match it up

Pair them with the Racer Lone Jersey for the matching graphic, or the full-mesh Racer Air Hunt Jersey if you want the top half vented as well. Add Radar Gloves and SX-1 v2 Knee Guards.
