Kestrel Sport Ireland: Football Academy Training Kit Comfort and Fit Evaluation
Kestrel Sport is a Ireland-based brand whose football academy training kit is one of its most demanding programmes. Performance data means nothing if the garment is uncomfortable. This evaluation covers how the recycled nylon interlock behaves on the body during football academy training kit work.

Kestrel Sport: Recycled Nylon Interlock in use during daily squad training in all weather
Evaluation background
The programme covers training shirts, shorts and warm-up tops, used for daily squad training in all weather. The environment is contact, sliding and heavy perspiration and the requirement written into the brief was tear resistance with colour consistency across a squad. 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 squad training in all weather 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 tear resistance with colour consistency across a squad, which is the priority Kestrel Sport set for this product.
Fit retention
Garments were measured after five and twenty washes. Growth stayed within tolerance, so the fit approved in sampling is the fit the customer eventually receives.

Verdict and recommendation
Comfort and fit were confirmed in wear, and the recycled nylon interlock is approved for bulk with the current pattern. For Kestrel Sport the practical next steps are to keep the current specification for the repeat, retain the shade standard, and issue AATCC 183 results with every lot so any claim can be supported with data.
