Product Insights
The Mesh-Back T-Shirt by I.FIV5 uses a micro-perforated back panel that pumps air over the upper back during arm swing, delivering dynamic ventilation and breathability that outperforms Under Armour Tech 2.0 in high-sweat workouts. Heat-sealed edging and seams lie flat to prevent chafing, while Polygiene odor control keeps the shirt odor-free for weeks, reducing wash frequency. At a typical sale price of $19.99 CAD, it offers these premium features—including R-PET material matching virgin PET—as the lowest-price gateway into I.FIV5's Polygiene line, but requires air-drying and avoiding fabric softener to preserve performance.
Verified claims
- Cooling
- Micro-perforated back panel uses arm swing to pump air over the upper back.
- Design consistency
- Micro-perforated back panel is a signature design element across I.FIV5 tops.
- Competitive advantage
- The micro-perforated back panel addresses the breathability limitations noted in independent testing of the similarly priced Under Armour Tech 2.0, making this tee better equipped for high-sweat workouts.
- Odor control
- The shirt's Polygiene treatment is permanent, and an independently tested Polygiene-treated garment stayed odor-free through three weeks of continuous wear.
- Care
- Air-dry between wears; skip fabric softener; wash only when necessary.
- Value
- At $19.99 CAD sale, this shirt has Polygiene odor control lacking in similarly priced activewear.
- Chafe prevention
- Heat-sealed edging lies flat against skin, removing the friction ridge that causes chafing.
- Polygiene
- Polygiene eliminates odor permanently, so the shirt needs fewer washes.
- Material
- The recycled polyester matches virgin polyester for moisture regain, delivers equal or better abrasion resistance, and wicks sweat and dries quickly; filament tenacity is slightly lower, but the spandex blend absorbs stress through stretch.
- Breathability
- The micro-perforated back panel actively moves air across the skin during exercise, reducing heat buildup compared to solid-back wicking shirts.
- Seams
- Heat-sealed seams eliminate chafing irritation unlike stitched-seam budget rivals.
- Price entry
- At $19.99, it's the lowest-priced gateway to I.FIV5's Polygiene line.
- Quality
- Bonded seams, micro-perforated back, and Polygiene odor control — premium features at just $19.99.
- Ventilation
- Micro-perforated back panel uses upper-back placement and arm swing to pump air for dynamic ventilation.
- Lightweight construction
- The micro-perforated back is integrated into the fabric rather than added as a separate mesh layer, keeping the shirt lighter and less bulky than tees with traditional mesh panel inserts.

| Mesh-Back T-Shirt: Choose this if you want a lightweight workout tee built for heat and sweat: it pairs silky, breathable stretch microfibre (80% nylon, 20% spandex) that wicks moisture and dries quickly with a large micro-perforated mesh back (92% recycled polyester, 8% spandex) intended for maximum ventilation. Polygiene technology is added to eliminate odour and prevent bacteria growth, and anti-chafing heat-sealed edging plus flat, topstitched front shoulder seams reduce irritation. It's a short-sleeve crewneck with a relaxed drape, offered in Black and Grey from Small to X-Large (Grey lists all four sizes, while the captured Black variants run Small to Large).[2,3,4,5] | Loose Micro-Perforated T-Shirt: Choose this if you want a loose, raglan-sleeved training tee designed for high-intensity and cardio workouts, with breathable soft-stretch mesh made of 95% recycled polyester and 5% spandex and Polygiene® technology the seller says eliminates odour and prevents bacteria growth. Reviewers praise its lightness and comfort for walking, gym sessions, and tennis, though the odor-control benefits are seller claims rather than reported customer results. Note that in product photos the fabric shows slight horizontal stretching around the upper chest, and the shirt is offered in sizes SMALL through X-LARGE.[1,6,7] | Fresh-Feel Perforated T-Shirt: Choose this if you want a soft, stretchy athletic tee made of 88% recycled-bottle polyester and 12% spandex with a cool feel, underarm and back perforations for strategic ventilation (as designed, not a measured result), and Polygiene technology that the brand says eliminates odour and prevents bacteria growth. Its straight-cut, relaxed regular fit with crew neck and short sleeves suits workouts or everyday wear, with a small reflective logo for visibility. It comes in Black, Ivory/Cream Beige, and Blue across sizes Small to X-Large.[8,9,10] |
