Halcyon Studio New Zealand: Triathlon Programme Durability and Abrasion Evaluation
Halcyon Studio is a New Zealand-based brand whose triathlon programme is one of its most demanding programmes. Abrasion is the most common reason a technical garment is retired. We evaluated the seamless circular knit against the contact surfaces found in triathlon programme.
Halcyon Studio: Seamless Circular Knit in use during swim, bike and run in a single event
Evaluation background
The programme covers trisuits, shorts and transition layers, used for swim, bike and run in a single event. The environment is transitions between water, wind and road and the requirement written into the brief was one fabric that performs wet and dry without chafe. Fabric was selected on that basis rather than on price alone.
Fabric under evaluation
| Parameter | Value |
|---|---|
| Fabric | Seamless Circular Knit |
| Composition | polyamide / elastane seamless |
| Weight | 220 GSM |
| Width | 165 cm |
| Primary function | removes side seams so contact points stop rubbing |
| Target | above 20000 abrasion cycles without yarn breakage |
| Test method | ASTM D4966 |
| Additional note | zoned structure knitted directly into the tube |
| 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 swim, bike and run in a single event. 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 transitions between water, wind and road, 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 Halcyon Studio 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 Halcyon Studio the practical next steps are to keep the current specification for the repeat, retain the shade standard, and issue ASTM D4966 results with every lot so any claim can be supported with data.
