Product Insights
The I.FIV5 Perforated Stretch Short (4" inseam, $69 CAD) is a performance running short that combines permanent odor control via Polygiene (tested for 4–5 days of daily wear without odor when aired out) with breathability from perforations, side vents, and a short inseam that accelerates cooling and evaporation. It prevents chafing through a built-in microfibre brief and anchored hem, while the 4" length reduces leg swing weight and ensures stride freedom. Made from 100% recycled polyester that performs within 2–3% of virgin in wicking and durability, it offers environmental benefits (45–85% less energy) without sacrificing quality. The tradeoff: the built-in liner lacks a phone pocket, so storage relies on front zippered pockets. Care requires cold wash and air drying. At over 30% less than Tracksmith Twilight Shorts with the same Polygiene, this Simons-exclusive, Canada-designed piece delivers premium functionality and value.
