Product Insights
The Performance Pacepro™ Perforated T-Shirt from INNER SELF is a 125gsm ultralight tee with laser-cut perforations that resist fraying, designed to keep the wearer ventilated from 10°C to 35°C. Its ventilation system—a racing-singlet feature uncommon in training tees at this price—uses side and back perforations to reduce chafing instead of raglan sleeves. Priced at $65 CAD, it undercuts the comparable Nike Stride Dri-FIT ADV by $3 while offering moisture-wicking, a reflective logo, and laser-cut ventilation. The athletic cut runs trimmer than standard Nike or UA sizing; order usual for a close fit or size up for looser. To preserve the reflective logo, wash every 8–12 runs in cold water with enzyme-free detergent, air-dry flat, and never use fabric softener or vinegar. This shirt is exclusive to Simons as part of the Montreal collection.

- Care instructions
Preserve the reflective logo by washing in cold water with enzyme-free detergent and air drying flat.
Why this is supported
The reflective logo uses microprisms or glass beads bonded with polyurethane adhesive, making it chemically and thermally sensitive. Industry testing shows that
reflectivity loss begins after just two hot-water cycles—even at 40°C
lifetips.alibaba.com. Therefore, cold water is mandatory.
Wash reflective running gear in cold water only, using a liquid detergent free of enzymes, optical brighteners, and bleach.
lifetips.alibaba.comFabric softener
, and vinegar’s acidity destabilizes polyurethane binders. For drying,
Air-dry flat—never tumble dry, iron, or hang in direct sun
lifetips.alibaba.combecause
Tumble drying exposes the reflective logo’s polyurethane adhesive to heat that softens and cracks it
Care for reflective prints and odor control — air_dry_flat_indoors. This regimen, along with washing every 8–12 runs instead of after every use, maintains reflectivity and odor control.
- Wash routine
Wash every 8–12 runs in cold water with a liquid detergent free of enzymes and optical brighteners.
Why this is supported
A quick post-run rinse fails to remove sweat-derived compounds that can etch reflective surfaces:
But this fails to remove **sweat-derived urea and fatty acids**, which form alkaline salts that etch reflective surfaces over time.
lifetips.alibaba.comThe recommended routine is to wash every 8–12 runs in cold water using a liquid detergent free of enzymes, optical brighteners, and bleach:
Wash reflective running gear in cold water only, using a liquid detergent free of enzymes, optical brighteners, and bleach.

lifetips.alibaba.com- Laundry additives
Never use fabric softener or vinegar; air-dry flat indoors.
Why this is supported
Fabric softener coats the reflective beads, reducing visibility:
Coats retroreflective glass beads, slashing nighttime reflectivity
