To provide reliable wind blocking and weather protection on exposed trail runs, the Acid Running Lightweight Running Jacket in Riverstone is constructed from an ultra light, water resistant technical ripstop nylon. This highly packable performance outer shell solves the challenge of unpredictable weather conditions forcing you to carry heavy outerwear by compressing down into its own internal pocket. Styled with a protective fitted hood, elasticated cuffs, a drop tail hem, and discreet ventilation slits under the arms, it ensures total mobility, breathability, and shield against chilling gusts.

Key Features

• Ultra lightweight technical ripstop nylon shell repels light rain and cuts through cold winds.
• Self stowing design allows the entire jacket to pack neatly into a zipped pocket.
• Fitted ergonomic hood stays secure on your head during high pace running strides.
• Underarm ventilation slits promote heat dispersal to prevent internal condensation buildup.
• Elasticated cuffs and adjustable hem seal out drafty winds and rain spray.
• Subtle Riverstone grey earth tone finished with reflective branding details for low light safety.

At Urban Industry We Recommend These For

• Trail running, fell running, unpredictable mountain routes, and cool weather road training.
• Carrying as an emergency protective outer layer in a running vest or belt pocket.
• Athletes needing an ultra light windproof jacket that offers complete weather coverage without adding weight.

Fit & Sizing Recommendations

• The brand notes that this style runs in an athletic, close to body silhouette to minimise fabric flap in wind.
• Acid Running advises opting for your regular size over a light singlet, or sizing up if you plan to wear it over thicker midlayers.
• Articulated sleeve patterning and flexible ripstop fabric ensure full arm movement through every stride.

Washing & Care Instructions

• Machine wash cold at 30 degrees using a gentle synthetic cycle.
• Avoid fabric softeners and bleaching agents, as they degrade water repellent fabric treatments.
• Hang dry naturally away from direct heat sources, radiators, or open fires.
• Do not tumble dry, iron, or dry clean to maintain seam integrity and technical performance.
