Kestrel Sport Ireland: Road Running Club Kit Durability and Abrasion Evaluation
Kestrel Sport is a Ireland-based brand whose road running club kit is one of its most demanding programmes. Abrasion is the most common reason a technical garment is retired. We evaluated the moisture-wicking polyester single jersey against the contact surfaces found in road running club kit.
Kestrel Sport: Moisture-Wicking Polyester Single Jersey in use during high cadence road training and race day
Evaluation background
The programme covers singlets, shorts and lightweight jackets, used for high cadence road training and race day. The environment is repeated perspiration and friction over long distances and the requirement written into the brief was low weight with uninterrupted moisture transport. Fabric was selected on that basis rather than on price alone.

| Primary function | moves sweat to the outer face so it can evaporate |
| Target | moisture management class 4-5 |
| Test method | AATCC 195 |
| Additional note | one-way transport index above 300 |
| Certification | OEKO-TEX Standard 100 |

Method
Fabric was abraded to ASTM D4966 against both a standard wool abradant and the actual contact surface used in high cadence road training and race day. Seam strength was tested to ISO 13936-2 in parallel.
Results
The fabric passed the agreed cycle count with no yarn breakage and seam opening stayed inside the 6 mm limit. Pilling remained at grade 4 or above at the end of the test.

Where wear appeared
Any surface change appeared first under repeated perspiration and friction over long distances, which is expected and is why we recommend panel placement rather than a single fabric across the whole garment.
Service life estimate
On this data the garment should complete a full competitive season before appearance becomes a reason to replace it, which is the commercial target Kestrel Sport set at the start.

Verdict and recommendation
Durability is sufficient for the intended use. Keep the current construction and revisit only if the garment moves into a higher abrasion category. For Kestrel Sport the practical next steps are to keep the current specification for the repeat, retain the shade standard, and issue AATCC 195 results with every lot so any claim can be supported with data.
