The Acid Running 2-in-1 Shorts in Riverstone offer a high-cadence training solution by combining a near-weightless technical shell with a supportive compression inner. Developed with a marble-grey tonal finish, this design removes the typical distractions of chafing and moisture build-up during intense sessions. The internal liner provides targeted support to the quads and hamstrings, while the moisture-wicking properties ensure the fabric dries rapidly, maintaining a light and comfortable feel even as your mileage increases.

At Urban Industry we recommend / Ideal For

• Marathon training and long-distance road runs requiring consistent muscle support
• Gym workouts and high-intensity interval training (HIIT) that demand total mobility
• Hot weather running thanks to the ventilated, quick-drying fabric construction
• Athletes seeking the benefits of a compression base layer without the extra bulk

Our Style, Fit & Sizing Recommendations

• This 2-in-1 model is designed with a performance fit, where the inner liner sits firmly against the leg
• We recommend choosing your standard size for a secure, supportive feel
• The Riverstone colourway provides a clean, neutral aesthetic that pairs easily with bright or monochrome technical tops
• The elasticated waistband provides a low-profile fit that sits comfortably beneath hydration belts or packs

Washing & Care Instructions

• Machine wash at 30º with similar colours to preserve the elasticity of the recycled polyester
• Avoid the use of fabric softeners as they can coat the fibres and reduce moisture-wicking efficiency
• Hang to air dry naturally, as the lightweight materials are engineered to dry quickly without a tumble dryer
• Wash the garment inside out to protect the secure zipper and the internal phone pocket

Our Acid Running 2-in-1 Shorts FAQs

1. How much support does the compression liner provide?
   The 10% elastane inner is designed to wrap the quads and hamstrings firmly, helping to reduce muscle vibration and fatigue during runs.

2. Will a large smartphone fit in the lining pocket?
   The discreet pocket is made from stretch fabric designed to hold most modern smartphones securely against the thigh to prevent bouncing.

3. Is the outer shell durable?
   Yes, while it feels exceptionally light, the recycled polyester weave is durable enough to handle the repetitive motion of long-distance training.

4. Does the liner cause overheating?
   The liner is specifically integrated to be rapidly drying and breathable, preventing the heat build-up often associated with traditional layering.
