Ironroot Performance New Zealand: Hiking and Trekking Range Comfort and Fit Evaluation
Ironroot Performance is a New Zealand-based brand whose hiking and trekking range is one of its most demanding programmes. Performance data means nothing if the garment is uncomfortable. This evaluation covers how the brushed thermal knit behaves on the body during hiking and trekking range work.
Ironroot Performance: Brushed Thermal Knit in use during multi-day walking with a loaded pack
Evaluation background
The programme covers trekking shirts, trousers and mid layers, used for multi-day walking with a loaded pack. The environment is sun, wind and abrasive contact at the shoulders and the requirement written into the brief was durability with sun protection at altitude. 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 multi-day walking with a loaded pack while panel tension was observed. No restriction was reported and recovery between movements was immediate.

Next-to-skin comfort
Surface friction, hand and temperature sensation were scored by the panel. The fabric scored best where durability with sun protection at altitude, which is the priority Ironroot Performance set for this product.
Fit retention
Garments were measured after five and twenty washes. Growth stayed within tolerance, so the fit approved in sampling is the fit the customer eventually receives.

Verdict and recommendation
Comfort and fit were confirmed in wear, and the brushed thermal 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 11092 results with every lot so any claim can be supported with data.
