Halcyon Studio Ireland: Road Running Club Kit Laboratory Test Report
Halcyon Studio is a Ireland-based brand whose road running club kit is one of its most demanding programmes. This report documents the laboratory qualification of the moisture-wicking polyester single jersey supplied to Halcyon Studio for its road running club kit. Every figure below was produced on bulk fabric, not on an approval swatch.

Halcyon Studio: 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.

Samples and conditioning
Three bulk lots were sampled at random and conditioned for 24 hours before testing. Results are reported as the worst of the three, which is the number a brand should plan around.
Test methods
The primary method was AATCC 195, supported by dimensional change to AATCC 135, pilling to ISO 12945-2 and colour fastness to ISO 105-C06.

Evaluation session with the Halcyon Studio team
Results
The fabric reached moisture management class 4-5, with one-way transport index above 300. All supporting tests passed the agreed limits, and the report carries the lot numbers so the results can be reproduced.
Interpretation
Numbers only matter against the use case. For road running club kit the relevant result is that the fabric keeps moves sweat to the outer face so it can evaporate after conditioning, which is what protects the wearer during high cadence road training and race day.

Verdict and recommendation
The bulk fabric met every agreed target. The lot is released and we recommend repeating the same test set on each future delivery of the moisture-wicking polyester single jersey. For Halcyon Studio 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.
