Product Information

SIDEWIND is a 12L messenger bag designed to move smoothly between riding and everyday transit. Its structure keeps excess volume down, with a size balance suited to commuting, short trips, and daily carry.

A FIDLOCK magnetic buckle is used for closure, allowing quick access even while riding. Dyneema® stretch material is placed at the sides to hold a bottle or small items. It also includes a stabilizer strap to reduce bag movement while riding.
