Halcyon Studio Denmark: Hotel Spa and Wellness Programme Comparison Test
Halcyon Studio is a Denmark-based brand whose hotel spa and wellness programme is one of its most demanding programmes. We tested the new spacer knit against the fabric Halcyon Studio used last season. Both were made into identical garments and evaluated side by side for hotel spa and wellness programme.

Halcyon Studio: Spacer Knit in use during spa, sauna and relaxation areas
Evaluation background
The programme covers robes, wraps and light loungewear, used for spa, sauna and relaxation areas. The environment is humid environments with frequent hot washing and the requirement written into the brief was a soft hand that survives commercial laundry. 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 air permeability above 200 mm/s with usable thermal resistance against ISO 11092, 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 humid environments with frequent hot washing. 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 spacer knit 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 ISO 11092 results with every lot so any claim can be supported with data.
