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.

Verified claims

Ventilation
Micro-perforations accelerate sweat evaporation and vent hot air for a cooling effect.
Value
At $39 CAD, breathability rivals $70 race-ready tops.
Perforation pattern
The shirt uses the same fabric construction across all seven color variants, so the perforation pattern is expected to be uniform.
Mechanism
Silver ions from Polygiene disrupt odor-causing bacteria on polyester.
Permanence
Polygiene is infused into the fabric; odor control does not wash away.
Multi-wear
Airing overnight restores freshness, enabling multiple wears between washes.
Recycled content
88% recycled polyester uses 45-85% less energy and 30-60% less CO2 than virgin.
Performance equivalence
Recycled polyester is chemically identical to virgin; no change in wicking or drying.
Wash frequency
Built-in Polygiene halves washing, reducing total environmental impact by one-third.
Material
88% recycled polyester equals virgin performance, halving energy and carbon.
Breathability
The micro-perforated construction provides high airflow typical of race-ready tops, at a fraction of the cost.
Fit
Order your usual size; the semi-slim cut comes from the pattern, not from sizing down.
Reflective logo
The shirt includes a reflective i.FiV5 logo for low-light visibility, a feature missing from the Patagonia Capilene Cool Daily ($49).
Care
Wash cold with mild detergent, avoid fabric softeners and bleach, and tumble dry low or air dry to preserve the Polygiene treatment and mesh.
Visibility
The shirt's reflective logo provides low-light visibility, a feature absent from the Patagonia Capilene Cool Daily.
Lightweight
The shirt is ultra-light and breathable, with buyers describing it as very lightweight for workouts.
Breathability vs cotton/polyester
The micro-perforated mesh is more breathable than standard cotton or polyester workout shirts.
