Product Insights
The I.FIV5 Micro-Perforated T-Shirt ($39 CAD) marries micro-perforations and cool-touch fabric for ventilation with raglan sleeves for uninhibited motion, while bonded Polygiene technology delivers odor control tested through 20-hour multi-sport and 3-week backcountry wear, enabling less frequent washing that reduces lifecycle environmental impact by 35%. Flat seams and buttery-soft fabric minimize chafing, and quick-dry, wrinkle-resistant performance suits running, training, and travel. However, buyers should note the semi-slim fit despite a regular cut label, order one size down for a fitted look, and expect the blue colorway to run a full size larger. As the only performance tee at this price with both micro-perforations and Polygiene, it prompts multi-color buying for rotation.
Verified claims
- Ventilation
- The micro-perforations are concentrated under the arms and across the upper back, and the cool-touch microfibre prevents heat from being trapped during workouts.
- Size advice
- The blue colorway fits a full size larger than the same labeled size in other colors, and one buyer who normally wears medium took a small because the shirt runs a bit large.
- Fit description
- Shirt has a semi-slim fit despite being labeled as regular cut.
- Sleeve design
- Raglan sleeves eliminate the shoulder seam, allowing a natural, binding-free range of overhead motion.
- Care
- Buyers describe the shirt as very soft and comfortable, and the cool-touch microfibre with flat seams helps prevent chafing.
- Odor control
- Independent wear tests of Polygiene-treated garments stayed odor-free through 20-hour multi-sport use and a 3-week backcountry trip.
- Polygiene technology
- Bonded into fibers, lasts garment lifetime with normal washing.
- Environmental benefit
- For a Polygiene-treated training tee, washing half as often reduces total environmental impact by 35%.
- Value
- Only performance tee at $39 CAD with both micro-perforations and Polygiene.
- Performance details
- Flatlock seams, raglan sleeves, micro-perforations, and cool-touch fabric suit running, training, and travel.
- Seam comfort
- Flat seams minimize friction during repetitive movements, reducing chafing risk.
- Workout performance
- The tee is designed to keep wearers cool and dry during high-intensity training, and buyers report it is airy and suited to running and strength workouts.
- Quick-dry
- Fabric dries quickly and resists wrinkles for easy care
- Multi-color buying
- Buyers often purchase the tee in several colors for different activities and easy rotation.
- Sizing
- The blue colorway fits a full size larger than the same labeled size in other colors.
- Lightweight
- Multiple buyers describe the tee as very light, and one says it is probably the lightest shirt they've owned.

High-intensity workouts, from running to strength training
A breathable, quick-dry stretch tee made for wear during high-intensity sports, with underarm and back perforations designed for strategic ventilation and raglan sleeves meant to allow freer movement. Reviewers report staying cool and comfortable even while sweating in hot-weather sessions, and describe it as light enough for activities ranging from running to strength training. Note that some reviewers mention the fabric is extremely thin, so delicate care may be needed to avoid damage.[1,2,4]
Multi-workout tee you can rewear between washes
For back-to-back training days, this tee is aimed at wearers who want to get several sessions out of one shirt before laundry day. In one reviewer's experience, it was worn for 20 hours over two weeks across 3-hour runs, spinning, mountain biking, and weight lifting — then stored in a gym bag next to shoes — without developing an odor. That's a single reported account, not a guaranteed result.[3]
A soft tee for workouts and everyday wear
Shoppers reach for this micro-perforated t-shirt for both exercise and casual wear, with its gentle, buttery-soft feel against skin earning praise for all-day comfort. One reviewer highlighted it as ideal for running, noting good quality and comfort. Reviewers report the sizing runs large and can vary between colors, so fit may take some attention when ordering without trying it on.[4]
A packable tee for travel and on-the-go days
Per a customer review summary, this micro-perforated t-shirt stays wrinkle-free and dries fast, which can make it easy to pack and wear while traveling or when you're out and about. This comes from a single review, so individual experiences may vary.[4]
Product comparison
Compared within this brand.
| Micro-Perforated T-Shirt: Choose this if you want a high-intensity workout tee for hot weather: it's a lightweight, stretchy recycled polyester-spandex mesh with moisture-wicking, quick-dry fabric, underarm and back perforations for ventilation, flat seams, and Polygiene odor control that one tester reported kept the shirt odor-free across 20 hours of wear without washing. Note that reviewers say the sizing runs large and can vary by color (the blue colorway fits especially large), so most size down for a flattering fit, and the extremely thin fabric may need delicate care to avoid damage.[1,3,4] | Micro-Perforated Semi-Slim Fit T-Shirt: Choose this for high-intensity workouts like running or HIIT and for casual everyday wear in hot weather: per customer reviews, the micro-perforated fabric delivers extreme ventilation and a barely-there weight, while the semi-slim fit with crew neckline and reflective strip at the lower back keeps it sporty. One caveat: reviewers found the fabric thinner and more ordinary-looking than the product photos suggest, so it may disappoint if you want a structured, premium-feeling tee.[5,6,7] | Micro-Perforated Cropped T-Shirt: Choose this if you want a cropped, loose boxy workout tee with a close-fitting crew neck and short sleeves, made of soft, stretch recycled polyester microfibre (63% recycled polyester, 32% nylon, 5% spandex). Micro-perforations in horizontal stripes across the whole shirt are stated by the brand to be for maximum ventilation, and Polygiene technology is asserted to eliminate odour and prevent bacteria growth, though these are manufacturer claims rather than tested results. It comes in Black, Ivory/Cream Beige, Khaki/Sage/Olive, and Slate Blue in sizes X-Small to X-Large.[8,9,10] |

J’adore
J’adore la légèreté du matériel
Perfect workout T
I have this T-shirt in many colours and wear them on rotation for Pilates and Yoga. Quick hand wash after class, hang the T up. Dries quickly and wrinkle free.
Awesome
Very very thin amd confortable Probably the lightest shirt I had Unfortunately no more pink Probably would have bought an exact same additional T-shirt I really get to like things sometimes
Light & Comfortable
Good shirt for functional strength training. I intend to get in more colours.
Micro-perforated T-shirt
I love the colour and the feel of the fabric.
T-shirt léger
T-shirt très agréable à porter car il est très léger ! Idéal pour l’entraînement ! Par contre fait un peu grand ! Habituellement je porte médium et j’ai dû prendre un small !
Perfect fit
Light, so comfy and airy. I love the fit and thinking of getting other Colors. Must have.
Parfait pour l'entraînement
Vêtements sport de qualité, confortable et pas cher. Idéal pour la coureuse que je suis!
Doux et léger
Ce t-shirt est doux et le tissu très léger et respirant. La coupe est avantageuse.
T-shirt microperforé bleu
J’ai acheté ce t-shirt dans plusieurs couleurs car il est très confortable. Je les ai tous pris de grandeur Small mais étonnement le bleu est plus grand. Il fait probablement la largeur d’un médium et pourtant l’étiquette marque Small.
Work out top
Lightweight, soft, and comfortable
