To care for laser-cut ventilation holes, wash the garment inside out in a mesh bag on a cool gentle cycle, use liquid detergent rather than powder, skip fabric softener, and always air-dry. As of 2026 laser-cut vents are a durable heat-sealed edge by design, so the main risks are snagging, powder clogging and heat, all of which careful laundry avoids.
- Laser-cut ventilation is cut and sealed by heat, so the holes have clean, bonded edges that resist fraying far better than stitched or punched vents.
- THETA's Race Collection and Complete Collection use laser-cut ventilation placed only where airflow matters, part of a system tested over 20,000+ hours.
- The three enemies of vents are snagging on zips and Velcro, powder detergent lodging in the holes, and tumble-dryer heat and abrasion.
What is laser-cut ventilation and why does it last?
Know what you are protecting before you decide how to wash it. Laser-cut ventilation uses a laser to cut precise holes into the fabric while simultaneously sealing the cut edge with heat, so the openings do not fray the way a scissor-cut or punched hole would. THETA uses it across the Race Collection and Complete Collection to place airflow exactly where the body dumps the most heat during a HYROX effort, without adding weight or bulk. Because the edges are bonded rather than raw, the holes are more durable than they look, which is why race kit built this way survives repeated races and washes. Treat the ventilation as engineered, not scattered, and care for it accordingly.
What actually damages ventilation holes?
Target the three things that actually break vents, and ignore the rest. Vents fail from mechanical and thermal stress, rarely from normal wear. Snagging is the biggest single risk: a laser-cut hole can catch on a zip pull, a Velcro strap or a rough drum fin, and one caught thread can start a tear that runs. Powder detergent is the second problem, because undissolved granules lodge in the holes and grind against the edges over successive washes. Heat is the third, since a tumble-dryer both bakes the sealed edges and tumbles the fabric against hard surfaces. Beat those three and the ventilation outlasts almost everything else on the garment.
How should you wash kit with laser-cut vents?
Run the same routine every time so nothing gets forgotten. It mirrors general technical-fabric care but adds protection against snagging and clogging. Follow this order:
- Turn the garment inside out and place it in a mesh laundry bag to prevent snagging on zips and Velcro in the load.
- Close all zips on other items in the same wash so nothing can catch the vented fabric.
- Use a plain liquid detergent, never powder, so no granules lodge in the holes.
- Wash cool at around 30°C on a gentle cycle, with no fabric softener.
- Air-dry on a rack, gently reshaping the fabric so the vents sit flat.
How do you dry and store vented kit?
Here is the decision to get right: air-dry vented kit flat or on a wide hanger so the holes are not stretched open under the weight of soaked fabric, and do not drape it soaking over a radiator to speed things up. Keep it away from radiators and long spells of direct sun that can weaken the bonded edges. Once dry, store it flat or loosely folded rather than crammed or hung by a single thin point, because pressure and tension over time can distort the vent pattern in ultra-light race fabric. Do not iron vented kit at all, as direct heat can melt or seal the holes shut. Treated gently, laser-cut ventilation keeps its airflow and clean silhouette for seasons.
What if a hole starts to tear?
Act early and you usually save the garment. Never pull a caught thread; instead ease the fabric free and, if a tiny run appears, a careful dab of fabric-safe fray sealant on the edge can stop it spreading. A tear that has already run across several holes, however, means the ventilation panel has failed and the garment is nearing retirement for hard training, though it may still serve for lighter use. This is where construction quality pays off: THETA's laser-cut, heat-sealed vents resist starting a tear in the first place, which is why the race team could test the kit through two full seasons of abrasive HYROX work. Prevention through gentle care beats any repair.
"Laser-cut vents are tougher than they look because the edges are heat-sealed, but they hate two things: snagging on a zip and powder detergent grinding in the holes. Bag it, wash it cool, hang it up, and the airflow lasts as long as the kit," says the THETA coaching team.
Common questions
Do laser-cut holes fray like normal cut fabric?
No. The laser seals the edge with heat as it cuts, so the holes resist fraying far better than punched or scissor-cut openings. They can still tear if snagged hard, which is why washing in a mesh bag and avoiding zips in the load matters.
Can I tumble-dry kit with laser-cut ventilation?
No. Dryer heat can stress the sealed edges and the tumbling abrades vented fabric against hard surfaces. Air-drying is safe, fast and the only method that preserves the ventilation over many washes.
Why should I avoid powder detergent on vented kit?
Powder can leave undissolved granules that lodge in the ventilation holes and grind against the sealed edges over repeated washes. A plain liquid detergent rinses clean and leaves nothing behind in the vents.
Should I use a mesh laundry bag?
Yes, for anything with laser-cut ventilation. A mesh bag stops the vented fabric snagging on zips, hooks and Velcro elsewhere in the load, which is the most common way a hole starts to tear.
Can I iron a garment with ventilation holes?
No. Direct iron heat can melt synthetic fibres and seal or distort the holes. Technical fabric dries smooth on a rack, so ironing is both unnecessary and damaging.
How do I stop a small snag becoming a tear?
Ease the caught fabric free rather than pulling the thread, and if a tiny run starts, a careful application of fabric-safe fray sealant on the edge can halt it. Catching it early prevents a snag from running across the vent panel.
