Ironroot Performance Finland: Tennis Academy Kit Comfort and Fit Evaluation
Ironroot Performance is a Finland-based brand whose tennis academy kit is one of its most demanding programmes. Performance data means nothing if the garment is uncomfortable. This evaluation covers how the power mesh warp knit behaves on the body during tennis academy kit work.

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.

Fit assessment
Size sets were fitted on live models and on a fit form. Fabric extension was measured at the stress points so the pattern could be corrected before bulk cutting.
Movement testing
Wearers performed the movements specific to daily court training and match play while panel tension was observed. No restriction was reported and recovery between movements was immediate.

Next-to-skin comfort
Surface friction, hand and temperature sensation were scored by the panel. The fabric scored best where sun protection with a clean structured appearance, which is the priority Ironroot Performance set for this product.

Verdict and recommendation
Comfort and fit were confirmed in wear, and the power mesh warp knit is approved for bulk with the current pattern. 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.
