Lumenfield Finland: Rowing Club Kit Laboratory Test Report
Lumenfield is a Finland-based brand whose rowing club kit is one of its most demanding programmes. This report documents the laboratory qualification of the brushed thermal knit supplied to Lumenfield for its rowing club kit. Every figure below was produced on bulk fabric, not on an approval swatch.
Lumenfield: Brushed Thermal Knit in use during early morning water sessions
Evaluation background
The programme covers rowing suits, base layers and shells, used for early morning water sessions. The environment is cold, wet conditions with friction at the seat and the requirement written into the brief was abrasion resistance with warmth when damp. 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 Lumenfield 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 rowing club kit the relevant result is that the fabric keeps traps warm air without adding weight after conditioning, which is what protects the wearer during early morning water sessions.

“Fifty washes later the fabric still performs. That is what convinced our buying team.” — Lumenfield 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 brushed thermal knit. For Lumenfield 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.
