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.
- Cooling
Uniform convective cooling intensifies with workout intensity.
Why this is supported
Secondary sources confirm the active convective cooling:
Micro-perforations allow air to circulate around the body, reducing heat buildup during workouts or competitions.
bushisports.comThis effect scales with movement intensity. The raglan sleeve design (
Loose fit with raglan sleeves for greater freedom of movement
modesens.com) ensures that the airflow is not blocked during overhead reach, completing an integrated ventilation system that maintains consistent cooling across the full range of motion.
- Material
Recycled polyester-spandex with odor control, moisture wicking, and durable perforations.
Why this is supported
The fabric is a REPREVE recycled polyester blend with Polygiene treatment, which
eliminates odour and prevents bacteria growth
modesens.com. Technical data confirms that the recycled polyester wicks moisture just as well as virgin polyester:
The moisture regain figure — 0.4% per ASTM D1909 — is identical for REPREVE and virgin PET

the feel and performance of Repreve recycled polyester, it’s virtually indistinguishable from virgin
wwd.com. The thermoplastic fibers resist fraying at the perforation edges, so the cooling structure remains intact through repeated washing. To preserve the treatment and perforations,
we typically recommend machine washing in cold water, gentle cycle, and air drying or tumble drying on low heat to preserve the technology.
What specific care instructions are recommended to preserve the micro-perforations and Polygiene odor control (e.g., machine drying vs air drying)?- Appearance
Micro-perforations are subtle; lighter colors may become sheer when stretched.
Why this is supported
The micro-perforations are designed to be subtle, so the shirt retains the look of a solid tee, albeit with ventilation.
the stretchy polyester-spandex blend can become sheer when stretched
How do the micro-perforations affect the shirt's opacity—will it be see-through when stretched or in lighter colors like white?This means buyers wanting full opacity, especially in lighter colors like white, may prefer a darker colorway.
- Sustainability Credentials
Independently traceable REPREVE polyester cuts emissions 42% versus virgin.
Why this is supported
The REPREVE polyester in this shirt is traceable and independently verifiable:
Every strand carries Unifi’s FiberPrint tracer — a proprietary additive blended at the resin stage that enables independent laboratories to verify REPREVE content in finished fabric.
natuclothes.comIts environmental footprint is also well-documented; a peer-reviewed Life Cycle Assessment reports 42% lower greenhouse gas emissions and 67% lower freshwater consumption compared to virgin polyester.
Unifi’s 2023 peer-reviewed Life Cycle Assessment reports 42% lower greenhouse gas emissions for REPREVE filament yarn versus virgin filament, alongside 67% lower freshwater consumption and 66% lower fossil fuel depletion.
natuclothes.comThe program’s scale — over 42 billion bottles converted since 2007 — adds further weight to these claims.
Since its launch in 2007, Repreve’s manufacturer (Unifi, Inc.) has transformed over 42 billion discarded plastic bottles into fiber for clothing and gear.
sportek.comTogether, these data points verify the credibility of the sustainability story.
- Value
Exclusive in-house design delivers REPREVE and Polygiene at $39 CAD.
Why this is supported
This shirt is an exclusive in-house design (i.FiV5 by Simons), which eliminates third-party branding costs.
i.FiV5 by Simons: an exclusive designed in Canada | AIR Collection
modesens.comAs a result, the $39 CAD price includes REPREVE recycled polyester and Polygiene odor control without a typical brand premium.
- Sizing guidance
Loose fit runs larger than a standard tee; sizing down is recommended.
Why this is supported
In the product's Q&A, the brand states that the loose fit runs larger and advises:
you may want to size down if you prefer a closer fit.
How does the 'loose fit' compare to a standard t-shirt size—is it true to size or does it run larger than usual?This sizing recommendation is reinforced by the material's performance: the recycled polyester is reported as
it’s virtually indistinguishable from virgin
wwd.com, so the fabric's stretch and comfort mirror conventional polyester-spandex, ensuring the sizing guidance remains consistent.
- Design
Loose cut with raglan sleeves maximizes range of motion and reduces chafe.
Why this is supported
The raglan sleeve design is described in deep research as
reducing chafe points under backpack straps and allowing unimpeded overhead reach
The AIR Collection: ultra-light and breathable design — raglan_sleeve_design, and the overall cut is
designed for mobility-first activewear rather than casual loungewear
The AIR Collection: ultra-light and breathable design — raglan_sleeve_design, confirming the shirt's focus on unrestricted movement.
- Opacity
Lighter colors may become sheer when the fabric is stretched; sizing down increases this risk.
Why this is supported
The product's Q&A notes a potential drawback:
the stretchy polyester-spandex blend can become sheer when stretched.
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 also become more visible in lighter colors. The loose fit reduces this effect during normal wear, but sizing down or dynamic movement may create tension that increases sheerness.
- Odor control
Polygiene silver-salt treatment prevents odor buildup between washes.
Why this is supported
The shirt features Polygiene technology:
PolygieneTM technology that eliminates odour and prevents bacteria growth
modesens.comThis silver-salt treatment inhibits bacteria even after multiple high-intensity sessions, allowing the shirt to be worn without washing every use.
- Freedom of movement
Raglan sleeves reduce chafing under backpack straps and allow unimpeded overhead reach.
Why this is supported
The raglan construction removes the shoulder seam,
reducing chafe points under backpack straps
The AIR Collection: ultra-light and breathable design — raglan_sleeve_designand
allowing unimpeded overhead reach
The AIR Collection: ultra-light and breathable design — raglan_sleeve_design. The seam-free shoulder also lies flat against the deltoids, reducing friction under tight outer layers. The intentionally roomy loose cut prevents any binding at the shoulders during high-reach arm movements, though
you may want to size down if you prefer a closer fit
How does the 'loose fit' compare to a standard t-shirt size—is it true to size or does it run larger than usual?.
- Durability
Thermoplastic polyester fibers and single-layer construction preserve micro-perforation integrity.
Why this is supported
The micro-perforations are cut into a single layer of REPREVE polyester jersey covering the entire torso and sleeves, eliminating weak points. The thermoplastic fibers inherently resist fraying at cut edges,
so the micro-perforations remain intact and uniform even after rigorous use and machine washing
Breathability and cooling from the micro-perforations — durable_perforation_integrityThe recycled polyester used is functionally identical to virgin, with the manufacturer stating it is
virtually indistinguishable from virgin
wwd.com- Care
Cold gentle cycle and low-heat drying maintain micro-perforations and Polygiene's odor control for multiple wears.
Why this is supported
The brand's Q&A specifies:
machine washing in cold water, gentle cycle, and air drying or tumble drying on low heat to preserve the technology
What specific care instructions are recommended to preserve the micro-perforations and Polygiene odor control (e.g., machine drying vs air drying)?. The Polygiene treatment is
designed to control odor even during high-intensity activities and is effective for multiple wears between washes
How effective is the Polygiene odor control for high-intensity activities—does it remain effective after several wears between washes?, so the shirt can be worn multiple times between washes.
- Sheerness
In light colors, the stretchy polyester can become sheer and perforations more visible.
Why this is supported
The brand's Q&A notes that
in lighter colors like white, they may be slightly more noticeable, and the stretchy polyester-spandex blend can become sheer when stretched
How do the micro-perforations affect the shirt's opacity—will it be see-through when stretched or in lighter colors like white?.
- Performance
REPREVE polyester performs identically to virgin in feel and wicking.
Why this is supported
Catalog verified that REPREVE feels and wicks identically to virgin polyester. Ingle stated that it is
virtually indistinguishable from virgin
wwd.com, and the moisture regain figure is
moisture regain figure — 0.4% per ASTM D1909 — is identical for REPREVE and virgin PET
natuclothes.com. This fiber has a long track record in activewear:
it started back in 2007 with Polartec and Patagonia among the yarn’s early adopters.
wwd.comAnd the 2023 LCA confirms no trade-off in feel or wicking.
- Environmental savings
Recycled polyester cuts greenhouse gas emissions by 42% versus virgin.
Why this is supported
