How do the micro-perforations affect the shirt's opacity—will it be see-through when stretched or in lighter colors like white?

The micro-perforations are small holes in the fabric, so in lighter colors like white, they may be slightly more noticeable, and the stretchy polyester-spandex blend can become sheer when stretched. We recommend trying the shirt in your desired color to check opacity.

What specific care instructions are recommended to preserve the micro-perforations and Polygiene odor control (e.g., machine drying vs air drying)?

We haven't published specific care instructions for this shirt, but for Polygiene-treated fabrics and micro-perforations, we typically recommend machine washing in cold water, gentle cycle, and air drying or tumble drying on low heat to preserve the technology.

How does the 'loose fit' compare to a standard t-shirt size—is it true to size or does it run larger than usual?

The loose fit is intentionally roomier than a standard t-shirt. Based on the product description, it runs larger than usual for greater freedom of movement, so you may want to size down if you prefer a closer fit.

How effective is the Polygiene odor control for high-intensity activities—does it remain effective after several wears between washes?

Polygiene is designed to control odor even during high-intensity activities and is effective for multiple wears between washes, as per the technology's claims. The product description states it 'eliminates odour and prevents bacteria growth.'

Product Insights

The I.FIV5 Loose Micro-Perforated T-Shirt provides uniform convective cooling that intensifies with workout intensity, using recycled REPREVE polyester-spandex with Polygiene odor control and moisture wicking, at $39 CAD. Its loose fit runs larger than standard, requiring sizing down for a closer fit, and raglan sleeves reduce chafing under backpack straps, but lighter colors may become sheer when stretched, especially when sized down.

Verified claims

Cooling: Uniform convective cooling intensifies with workout intensity.
Material: Recycled polyester-spandex with odor control, moisture wicking, and durable perforations.
Appearance: Micro-perforations are subtle; lighter colors may become sheer when stretched.
Sustainability Credentials: Independently traceable REPREVE polyester cuts emissions 42% versus virgin.
Value: Exclusive in-house design delivers REPREVE and Polygiene at $39 CAD.
Sizing guidance: Loose fit runs larger than a standard tee; sizing down is recommended.
Design: Loose cut with raglan sleeves maximizes range of motion and reduces chafe.

Deep Research

The AIR Collection: ultra-light and breathable design

With raglan sleeves that extend in one piece to the collar, the traditional shoulder seam is removed, reducing chafe points under backpack straps and allowing unimpeded overhead reach — this construction detail is an immediate signal that the shirt was designed for mobility-first activewear rather than casual loungewear.
Designed in Canada exclusively for Simons, the AIR Collection is the retailer's in-house activewear line, giving this shirt a focused performance design that cuts out branding premiums — the $39 CAD price reflects a direct-to-consumer value that third-party labels can't match.
The shift to REPREVE polyester — a specific, traceable recycled fiber — means this shirt delivers the same wicking and quick-dry performance as virgin polyester while diverting plastic bottles from waste streams; it's a functional fabric upgrade that also tells a sustainability story.
Instead of relying on mesh panels, the entire body fabric is engineered with tiny perforations that let heat escape uniformly, so the shirt won't billow in the wind like a mesh tank but still actively cools — a subtle performance detail that keeps the look refined enough for errands post-workout.
The Polygiene treatment uses a low-concentration silver salt to inhibit bacterial growth on the fabric, so the shirt can be worn for multiple sessions without developing odor — a design choice that reinforces the AIR Collection's low-maintenance, grab-and-go concept.

What REPREVE recycled polyester brings to the shirt

Every strand of REPREVE carries Unifi's proprietary FiberPrint additive, so independent labs can authenticate the recycled content in the finished shirt — the recycled-bottle claim is auditable, not just a marketing line.
Unifi's CEO says REPREVE feels and performs 'virtually indistinguishable from virgin' polyester, so the shirt's soft hand, stretch, and moisture-wicking capability are uncompromised by the recycled content.
At 0.4% moisture regain, REPREVE polyester wicks sweat and dries just as fast as virgin PET — critical for a micro-perforated training shirt designed to stay light during high-output workouts.
Unifi's 2023 LCA found REPREVE filament yarn cuts greenhouse gas emissions by 42%, freshwater consumption by 67%, and fossil fuel depletion by 66% versus virgin polyester, so this shirt's material has a substantively smaller environmental footprint across the three most impactful categories.
Unifi has converted over 42 billion post-consumer bottles into REPREVE since 2007, and early adopters like Patagonia and Polartec have used it in performance gear for nearly two decades — the fiber is an established, industrial-grade material, not an experiment.

Breathability and cooling from the micro-perforations

The entire shirt—back, chest, and sleeves—relies on a single layer of micro-perforated jersey, providing uniform airflow that vents heat evenly across the torso rather than concentrating it behind a few mesh panels.
During physical activity, the micro-holes create a constant exchange of air—cooler outside air flows in while heated body air escapes—lowering skin temperature more effectively than a solid tee, with the cooling effect scaling up as your movement increases.
The thermoplastic polyester fibers inherently resist fraying at cut edges—unlike natural fibers that unravel—so the micro-perforations remain intact and uniform even after rigorous use and machine washing, preserving the shirt's breathability over time.
