Ironroot Performance Switzerland: Gym and Strength Training Line Durability and Abrasion Evaluation
Ironroot Performance is a Switzerland-based brand whose gym and strength training line is one of its most demanding programmes. Abrasion is the most common reason a technical garment is retired. We evaluated the recycled nylon interlock against the contact surfaces found in gym and strength training line.
Ironroot Performance: Recycled Nylon Interlock in use during resistance training and circuit work
Evaluation background
The programme covers leggings, training tops and shorts, used for resistance training and circuit work. The environment is short bursts of high load against equipment surfaces and the requirement written into the brief was squat-proof coverage with recovery after repeated stretch. Fabric was selected on that basis rather than on price alone.
Fabric under evaluation
| Parameter | Value |
|---|---|
| Fabric | Recycled Nylon Interlock |
| Composition | 78% GRS recycled nylon / 22% spandex |
| Weight | 270 GSM |
| Width | 175 cm |
| Primary function | stays fully opaque under tension while carrying a recycled claim |
| Target | opacity above 96% at 30% extension |
| Test method | AATCC 183 |
| Additional note | GRS chain of custody documents |
| 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 resistance training and circuit work. 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 short bursts of high load against equipment surfaces, 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 Ironroot Performance 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 Ironroot Performance 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.
