Halcyon Studio Sweden: Yoga and Pilates Studio Programme Comparison Test
Halcyon Studio is a Sweden-based brand whose yoga and pilates studio programme is one of its most demanding programmes. We tested the new recycled nylon interlock against the fabric Halcyon Studio used last season. Both were made into identical garments and evaluated side by side for yoga and pilates studio programme.

Halcyon Studio: Recycled Nylon Interlock in use during mat-based studio sessions and long holds
Evaluation background
The programme covers leggings, crop tops and studio shorts, used for mat-based studio sessions and long holds. The environment is warm, humid studios with sustained low-load stretch and the requirement written into the brief was a soft hand with full coverage through every pose. Fabric was selected on that basis rather than on price alone.

What was compared
Construction, weight and colour were held constant. The only difference was the fabric, which is the only way a comparison tells you anything useful.
Laboratory comparison
The new fabric reached opacity above 96% at 30% extension against AATCC 183, while the previous material missed the same target. Comfort measurements were closer, which is expected because hand had already been approved.

Wear comparison
Over four weeks the difference appeared during warm, humid studios with sustained low-load stretch. Wearers described the new version as cleaner and lighter in use, even though the scales said the two garments weighed the same.
Cost comparison
The upgrade adds a modest amount per garment. Measured against the return rate of the previous season, the change pays for itself within a single drop.

Verdict and recommendation
The new recycled nylon interlock outperformed the previous fabric on every measured criterion and we recommend switching the whole programme over. For Halcyon Studio 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.
