Halcyon Studio New Zealand: Triathlon Programme Field Test Report
Halcyon Studio is a New Zealand-based brand whose triathlon programme is one of its most demanding programmes. Halcyon Studio runs its triathlon programme across New Zealand and asked us to prove the fabric in the field rather than in a brochure. This report covers a full season of real use with seamless circular knit.
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 | 170 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 |

Test scope
Twenty garments were issued to regular participants and tracked for eight weeks. Every item was used for swim, bike and run in a single event and laundered under the same domestic conditions, so the only real variable was wear.
Conditions covered
The programme ran through transitions between water, wind and road. That is the environment the fabric has to survive, and it is harsher than any laboratory chamber we could have built.

What we measured
Garments were inspected every two weeks for surface wear, seam condition, dimensional change and retained hand. Fabric was retested at the end of the period against ASTM D4966.
What users reported
Participants logged comfort, drying behaviour and any irritation. The recurring comment was that the seamless circular knit stayed comfortable at the point where one fabric that performs wet and dry without chafe would normally be lost.

Verdict and recommendation
Field testing confirmed the laboratory picture. The seamless circular knit held its above 20000 abrasion cycles without yarn breakage across the whole season and we recommend it for the next programme without change. 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.
