La Sportiva | Flow 5-Inch Technical 2-in-1 Running Shorts - Men's

Maximum Ventilation for Deep Trail Progress

When you are committing to a long, ambitious day on the singletrack or pacing yourself through a humid weekend training block under a quiet forest canopy, overheating can quickly stall your momentum. The La Sportiva Flow 5-Inch Technical 2-in-1 Running Shorts are engineered precisely for high-output, long-distance performance. Featuring integrated laser-cut ventilation zones, these shorts facilitate active airflow to keep you cool when the midday heat rises. The outer shell is designed with an innovative overlapping side panel construction, allowing the shorts to flex naturally with your body on steep inclines and technical climbs without ever pulling or restricting your stride.

Premium 2-in-1 Support and Anti-Chafe Protection

True comfort on extended trail runs requires a flawless base layer. The Flow Shorts feature a premium built-in liner brief with an extended 7.5-inch inseam that provides targeted muscle support and total protection against inner-thigh friction. To ensure the liner stays perfectly in place while you travel over rolling coastal terrain, the hems are finished with a low-profile silicone grip that eliminates riding up or bunching. The entire short utilizes premium bonded seams rather than traditional stitching, creating ultra-flat edges that minimise chafing and significantly boost long-term durability against gear abrasion.

Innovative Storage and the Integrated PoleGrip System

Managing your equipment payload on the move shouldn't mean dealing with a bouncing, unstable pack. The Flow Shorts are equipped with a highly functional storage layout, including a dedicated drop-in left thigh pocket on the inner liner for your phone or nutrition, and a secure zippered rear mesh pocket for keys or cards. Flanking the rear pocket is La Sportiva's clever PoleGrip System—two adjustable, reflective elastic loops designed to carry a lightweight shell jacket or a pair of folding trekking poles completely bounce-free. If you are keeping things streamlined for a quick neighborhood track workout or a session at the gym, the loops can be entirely removed for a clean, minimalist look.
