Product Insights
INNER SELF’s Performance Micro-Perforated T-Shirt is an ultralight 125 GSM microfibre polyester running tee made for regular daily runs, warm-weather running, HIIT, and lighter training, with quick-dry wicking built into the yarn rather than a wash-out finish and laser-cut micro-perforations mapped to the upper back and underarms for targeted cooling where runners wet out first; the perforations are laser-sealed to resist fraying and keep holes true without contacting the fabric, preserving stretch and shape, and they add no bulk or chafe by keeping a mesh-panel seam out of the armpit. The core tradeoff is airflow: micro-perforations trade peak airflow for smoothness and move less air than open mesh. The silky, dry-touch sub-denier yarn complements a relaxed cut that reads large—size down for a closer fit, though X-Small buyers cannot size down further. One Off White colorway covers four sizes (X-Small to Large) at 39.95 CAD with no size-based upcharge; it is currently out of stock and the care label requires hang drying to protect the spandex and laser-cut perforations, while the chest wordmark is a dawn/dusk reflective accent only, not certified EN ISO 20471 or ANSI/ISEA 107 hi-vis.
Verified claims
- Targeted cooling
- Perforations map to the upper back and underarms, the zones runners wet out first.
- Airflow
- Micro-perforations trade peak airflow for smoothness, moving less air than open mesh.
- Comfort
- Micro-perforations add no bulk or chafe, and keep a mesh-panel seam out of the armpit.
- Fray resistance
- Laser-sealed edges prevent fraying after repeated washing.
- Stretch recovery
- Non-contact laser perforation retains the fabric's stretch and shape.
- Care
- The care label requires hang drying to protect the spandex and the laser-cut perforations.
- Fit
- Relaxed fit reads large; sizing down one gives a closer, less boxy cut.
- Size range
- Four sizes, X-Small to Large; X-Small buyers cannot size down further.
- Variants
- One Off White colorway at one price across all four sizes.
- Moisture wicking
- The quick-dry wicking lives in the microfibre polyester yarn itself, not a finish that washes out
- Durability
- Laser-sealed perforation edges resist fraying, and cutting by light keeps the holes true to pattern
- Fabric weight
- The INNER SELF Performance Micro-Perforated T-Shirt is an ultralight 125 GSM tee.
- Hand feel
- Sub-denier microfibre yarn gives a silky, dry-touch hand instead of a plasticky synthetic feel
- Running suitability
- Built for warm-weather running and HIIT, and fine for lighter training.
- Sizing
- Body cut with extra room; buyers report it runs large, so size down for a closer fit.
- Performance longevity
- Quick-dry wicking is built into the yarn, so it survives repeated laundering.
- Reflective visibility
- Chest logo gives a dawn/dusk reflective accent, not full-coverage safety
- High-visibility certification
- The reflective chest mark is decorative, not EN ISO 20471 or ANSI/ISEA 107 certified hi-vis
- Brand philosophy
- Made for regular daily runs, with a small chest wordmark as the only graphic.
- Reflective branding
- Reflective chest wordmark is a dawn/dusk visibility accent, not certified hi-vis.
- Handfeel
- Sub-denier microfibre yarn makes the synthetic knit feel silky, not plasticky.
- Pricing
- All four sizes are 39.95 CAD — no size-based upcharge.

Compared within this brand.
| Performance Micro-Perforated T-Shirt: Choose this if you want an ultralight (125 GSM) relaxed-fit short-sleeve tee for workouts or warm weather, made from a soft stretch polyester-spandex blend described as breathable, quick-dry, and moisture-wicking. Laser-cut micro-perforated zones at the back and underarms add ventilation, and the chest logo is reflective for low-light visibility. It comes in an Off White color in sizes X-Small to Large, with a loose, slightly boxy silhouette and dropped shoulders.[2,3,4] | Performance Pacepro™ Perforated T-Shirt: Choose this if you want an ultralight running T-shirt for warmer workouts: the brand specifies a temperature range of 10°C to 35°C (though it is unclear whether that is a recommended-use range), and the soft stretch microfibre jersey (88% polyester, 12% spandex) wicks away moisture, with laser-perforated back ventilation and underarm ventilation zones for added airflow. It is designed with a relaxed athletic cut, crew neck, reflective logo, and comes in Black, White, and Burgundy in sizes SMALL to X-LARGE.[1,5,6] | Lightweight Merino Long-Sleeve T-Shirt: Choose this if you want a relaxed-fit, long-sleeve crew-neck layer in an ultra-light 50% merino wool, 50% modal blend described by the brand as naturally temperature-regulating, odour-resistant, breathable and moisture-wicking. Its flatlock seams and raglan sleeves suit everyday and activity wear, and it comes in sizes small to X-large in Black or Ivory/Cream Beige. Note the weight is listed at 140 GSM (lightweight) on the retailer page, though a GearJunkie review lists it at 165 GSM for all-season conditions.[7,8] |
