Product Insights
The Fitted Stretch Windbreaker Jacket by I.FIV5 delivers a close athletic fit with 10-20% stretch from 100% polyester knit (50% reprocessed) without spandex, permanent Polygiene odor control tested for 4-5 days of active wear and Medical Class 1 skin-safe, plus recycled silver that is bluesign, Oeko-Tex, and REACH certified. Underarm jersey inserts provide targeted ventilation for high-intensity movement, but allow cold drafts at standstill. The windproof design reduces drag, while recycled polyester cuts carbon footprint 60-70% and performs identically to virgin—offering better value than competitors lacking recycled stretch and Polygiene, though standard zippers make it not water-resistant.
