Product Insights
The I.FIV5 Micro-Perforated Semi-Slim Fit T-Shirt ($39) combines micro-perforations for rapid sweat evaporation and cooling, rivaling $70 race-ready tops in breathability, with permanent Polygiene odor control that halves washing and reduces environmental impact by one-third, made from 88% recycled polyester (chemically identical to virgin, using 45-85% less energy and 30-60% less CO2), plus a reflective logo for visibility, but requires cold washing and no fabric softener to maintain performance.
