Product Insights
The I.FIV5 Micro-Perforated Racerback Tank at $29 CAD delivers full-torso micro-perforations for even airflow and rapid drying, while velvety microfibre stays smooth and non-clinging. Polygiene treatment lasts the garment's lifetime, reducing odor between washes and enabling multi-wear freshness, and the 90% recycled polyester with bluesign and Oeko-Tex certification supports sustainability. However, the relaxed fit features large armholes that gape overhead, and lighter colors are semi-transparent, requiring a nude sports bra for modest coverage.
- Breathability
Full-torso micro-perforations deliver even airflow and rapid drying.
Why this is supported
The I.FIV5 tank's micro-perforated fabric spans the entire torso, not just the armholes or back trim. As bushisports.com explains,
Micro-perforations allow air to circulate around the body, reducing heat buildup during workouts or competitions.
bushisports.comThese holes also act as direct exits for moisture vapor. Ugawear.com describes how
The second-skin fit keeps the fabric against the skin so vapor travels only a fraction of a millimeter to escape,
the micro-perforated fabric stays in direct contact with your skin instead of flapping — this maximizes the cooling effect because the sweat vapor has to travel only a fraction of a millimeter to escape through the perforations
Breathability from micro-perforations — second_skin_ventilation_lock_inThe microfibre jersey wicks moisture and dries quickly, as noted by modesens.com:
Silky, breathable stretch microfibre wicks away moisture and dries quickly
modesens.comTogether, these features keep the tank ventilated and lightweight during intensive sessions.
- Fabric feel
Velvety microfibre stays smooth and non-clinging during exercise.
Why this is supported
Customers report the microfibre remains comfortable even during sweaty cross-training:
Parfaite pour le crossfit Prix/qualité vraiment bien J’adore la couleur rose.
Customer review, March 18, 2026The velvety fabric surface stays away from the skin and does not become sticky, aided by the micro-perforations that prevent waterlogging. Modesens.com describes the material as
Silky, breathable stretch microfibre wicks away moisture and dries quickly
modesens.comThese properties reduce friction and inhibit clinging during repetitive arm movements.
- Odor control
Polygiene and quick drying reduce odor between washes.
Why this is supported
The micro-perforations keep the fabric dry, which reduces the damp conditions bacteria thrive in, while the Polygiene treatment directly stops odour:
Polygiene StayFresh is based on silver chloride, a salt that is naturally present in water and soil. The silver ions in the salt make it impossible for the bacteria responsible for bad smells to multiply, stopping odor in its tracks
polygiene.comThis combination means the tank stays fresh after multiple uses, contrasting with standard synthetics that need laundering after one wear—as Outside Online notes:
Synthetics, on the other hand, get smelly and often need to be laundered after a single use.
outsideonline.com- Value comparison
$29 CAD — full-body micro-perforation vs. trim-only mesh at similar price.
Why this is supported
The I.FIV5 tank, at $29 CAD, uses full-body micro-perforation for ventilation, whereas a competitor with a similar price uses a more limited approach:
Breathable mesh trim along arm openings and at racerback.
oldnavy.gap.comThat competitor relies on Go-Dry moisture-wicking technology:
Go-Dry moisture-wicking technology keep you comfortable and dry.
oldnavy.gap.comThe I.FIV5 tank adds full-torso perforation, a velvety feel, and Polygiene odor control, offering a more comprehensive package at a comparable price.
At $29 CAD, the tank combines Polygiene anti-odor and quick-drying microfibre. Comparable products either lack anti-odor (Old Navy:
) or use an unspecified treatment (Quince:
This tank is sustainable, moisture-wicking, anti-odor, and super-soft.
quince.com). Only the I.FIV5 tank pairs a named, permanent anti-odor treatment with fast-drying fabric.
- Certifications
Certified by bluesign and Oeko-Tex Eco-Passport.
Why this is supported
Polygiene states they are accredited by bluesign and have Oeko-Tex Eco-Passport and REACH compliance:
We’re accredited by bluesign, which promotes consumer safety, low impact manufacturing and responsible use of resources; Oeko-Tex Eco-Passport which supports responsible manufacturing and supply chains; and we have REACH compliance, the EU’s chemicals legislation.
polygiene.com- Fit
The relaxed torso fit is paired with large armholes that gape overhead.
Why this is supported
The brand describes the fit as
close, second-skin fit — it's snug but not compressive.
How does this tank fit? Is it true to size, or designed to be tight/compression or loose?. However, customer reviews note the armholes are
sous des bras très grands
Customer review, April 1, 2026(very large under the arms), causing gaping during overhead movements. The brand recommends
ordering your usual size
How does this tank fit? Is it true to size, or designed to be tight/compression or loose?to achieve the intended fit. The full-perforation design, unlike competitors that use
Breathable mesh trim along arm openings and at racerback.
oldnavy.gap.com, lacks structural reinforcement, which contributes to the armhole gaping. The stretch edging at the armholes helps in static positions but cannot prevent fabric from pulling away during dynamic movement. If the fit loosens over time through wear or improper care, the ventilation performance also decreases.
- Sheerness
Lighter colors are semi-transparent; a nude sports bra is needed for modest coverage.
Why this is supported
A customer review describes the fabric as
Très transparente
Customer review, April 1, 2026(very transparent). The micro-perforated construction provides
Micro-perforated back for maximum ventilation
modesens.com, but this ventilation comes at the cost of opacity in lighter colors, necessitating a nude sports bra for modest coverage.
- Moisture management
Wicks moisture, vents vapor, and dries quickly, staying lightweight.
Why this is supported
The microfibre jersey's moisture management is confirmed by multiple sources. A product listing states that it
wicks away moisture and dries quickly
modesens.comwhile the micro-perforations act as a
superhighway for moisture vapor
ugawear.comallowing sweat to evaporate directly. Customer reviews affirm the breathability, stating the
breathable micro-perforated fabric and relaxed fit keep you cool and unrestricted

- Eco-friendly
90% recycled polyester from bottles, with bluesign and Oeko-Tex Eco-Passport certified finishing.
Why this is supported
The material is 90% recycled polyester from plastic bottles, and the Polygiene treatment carries bluesign and Oeko-Tex Eco-Passport certifications, meaning the finishing process adds no extra water or energy and reduces the need for frequent washing, lowering environmental impact.
- Versatility
Reflective logo and popular colors come with oversized armholes and sheerness in light shades.
Why this is supported
The reflective i.FIV5 logo adds low-light safety for outdoor training, a feature absent in similar-priced Old Navy and Quince tanks.
Très transparente et sous des bras très grands
Customer review, April 1, 2026— the low weight fabric can be sheer in light colors, and the oversized armholes may expose more than intended during overhead movements. Conversely, buyers appreciate the style:
Parfaite pour le crossfit Prix/qualité vraiment bien J’adore la couleur rose.
Customer review, March 18, 2026The combination of visible color options and a relaxed fit makes the tank a popular choice for both gym and athleisure wear.
- Care
