Ironroot Performance Finland: Martial Arts and Grappling Range Comfort and Fit Evaluation
Ironroot Performance is a Finland-based brand whose martial arts and grappling range is one of its most demanding programmes. Performance data means nothing if the garment is uncomfortable. This evaluation covers how the silver ion antibacterial knit behaves on the body during martial arts and grappling range work.

Ironroot Performance: 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.

Fit assessment
Size sets were fitted on live models and on a fit form. Fabric extension was measured at the stress points so the pattern could be corrected before bulk cutting.
Movement testing
Wearers performed the movements specific to grappling and repeated mat contact while panel tension was observed. No restriction was reported and recovery between movements was immediate.

Verdict and recommendation
Comfort and fit were confirmed in wear, and the silver ion antibacterial knit is approved for bulk with the current pattern. For Ironroot Performance 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.
