Bluearbor Athletics Sweden: Martial Arts and Grappling Range Field Test Report
Bluearbor Athletics is a Sweden-based brand whose martial arts and grappling range is one of its most demanding programmes. Bluearbor Athletics runs its martial arts and grappling range across Sweden and asked us to prove the fabric in the field rather than in a brochure. This report covers a full season of real use with silver ion antibacterial knit.
Bluearbor Athletics: Silver Ion Antibacterial Knit in use during grappling and repeated mat contact
Evaluation background
The programme covers training tops, shorts and rash guards, used for grappling and repeated mat contact. The environment is high friction and frequent industrial laundering and the requirement written into the brief was tear strength with antibacterial protection. Fabric was selected on that basis rather than on price alone.

Test scope
Twenty garments were issued to regular participants and tracked for eight weeks. Every item was used for grappling and repeated mat contact and laundered under the same domestic conditions, so the only real variable was wear.
Conditions covered
The programme ran through high friction and frequent industrial laundering. That is the environment the fabric has to survive, and it is harsher than any laboratory chamber we could have built.
Evaluation session with the Bluearbor Athletics team
What we measured
Garments were inspected every two weeks for surface wear, seam condition, dimensional change and retained hand. Fabric was retested at the end of the period against ISO 20743.
What users reported
Participants logged comfort, drying behaviour and any irritation. The recurring comment was that the silver ion antibacterial knit stayed comfortable at the point where tear strength with antibacterial protection would normally be lost.

Verdict and recommendation
Field testing confirmed the laboratory picture. The silver ion antibacterial knit held its bacterial reduction above 99% across the whole season and we recommend it for the next programme without change. For Bluearbor Athletics the practical next steps are to keep the current specification for the repeat, retain the shade standard, and issue ISO 20743 results with every lot so any claim can be supported with data.
