Bluearbor Athletics Denmark: Hotel Spa and Wellness Programme Laboratory Test Report
Bluearbor Athletics is a Denmark-based brand whose hotel spa and wellness programme is one of its most demanding programmes. This report documents the laboratory qualification of the brushed thermal knit supplied to Bluearbor Athletics for its hotel spa and wellness programme. Every figure below was produced on bulk fabric, not on an approval swatch.
Bluearbor Athletics: Brushed Thermal 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.

Samples and conditioning
Three bulk lots were sampled at random and conditioned for 24 hours before testing. Results are reported as the worst of the three, which is the number a brand should plan around.
Test methods
The primary method was ISO 11092, supported by dimensional change to AATCC 135, pilling to ISO 12945-2 and colour fastness to ISO 105-C06.
Evaluation session with the Bluearbor Athletics team
Results
The fabric reached thermal resistance above 0.08 m2K/W, with warmth held after 30 washes. All supporting tests passed the agreed limits, and the report carries the lot numbers so the results can be reproduced.
Interpretation
Numbers only matter against the use case. For hotel spa and wellness programme the relevant result is that the fabric keeps traps warm air without adding weight after conditioning, which is what protects the wearer during spa, sauna and relaxation areas.

Verdict and recommendation
The bulk fabric met every agreed target. The lot is released and we recommend repeating the same test set on each future delivery of the brushed thermal knit. For Bluearbor Athletics 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.
