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

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 Kestrel Sport team
Results
The fabric reached air permeability above 200 mm/s with usable thermal resistance, with compression set below 10%. 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 cushions and ventilates in a single piece of fabric after conditioning, which is what protects the wearer during spa, sauna and relaxation areas.

“Fifty washes later the fabric still performs. That is what convinced our buying team.” — Kestrel Sport Technical Team

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 spacer knit. For Kestrel Sport 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.
