Ironroot Performance Norway: Tennis Academy Kit Comparison Test
Ironroot Performance is a Norway-based brand whose tennis academy kit is one of its most demanding programmes. We tested the new power mesh warp knit against the fabric Ironroot Performance used last season. Both were made into identical garments and evaluated side by side for tennis academy kit.
Ironroot Performance: Power Mesh Warp Knit in use during daily court training and match play
Evaluation background
The programme covers polo shirts, skirts and dresses, used for daily court training and match play. The environment is direct sun with repeated lateral movement and the requirement written into the brief was sun protection with a clean structured appearance. Fabric was selected on that basis rather than on price alone.

What was compared
Construction, weight and colour were held constant. The only difference was the fabric, which is the only way a comparison tells you anything useful.
Laboratory comparison
The new fabric reached air permeability above 400 mm/s against ISO 11092, while the previous material missed the same target. Comfort measurements were closer, which is expected because hand had already been approved.

Wear comparison
Over four weeks the difference appeared during direct sun with repeated lateral movement. Wearers described the new version as cleaner and lighter in use, even though the scales said the two garments weighed the same.
Cost comparison
The upgrade adds a modest amount per garment. Measured against the return rate of the previous season, the change pays for itself within a single drop.

Verdict and recommendation
The new power mesh warp knit outperformed the previous fabric on every measured criterion and we recommend switching the whole programme over. For Ironroot Performance the practical next steps are to keep the current specification for the repeat, retain the shade standard, and issue ISO 11092 results with every lot so any claim can be supported with data.
