Trailhead Union New Zealand: Hiking and Trekking Range Field Test Report
Trailhead Union is a New Zealand-based brand whose hiking and trekking range is one of its most demanding programmes. Trailhead Union runs its hiking and trekking range across New Zealand 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 brushed thermal knit.
Trailhead Union: 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.

Test scope
Twenty garments were issued to regular participants and tracked for eight weeks. Every item was used for multi-day walking with a loaded pack and laundered under the same domestic conditions, so the only real variable was wear.
Conditions covered
The programme ran through sun, wind and abrasive contact at the shoulders. That is the environment the fabric has to survive, and it is harsher than any laboratory chamber we could have built.

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 11092.
What users reported
Participants logged comfort, drying behaviour and any irritation. The recurring comment was that the brushed thermal knit stayed comfortable at the point where durability with sun protection at altitude would normally be lost.

Verdict and recommendation
Field testing confirmed the laboratory picture. The brushed thermal knit held its thermal resistance above 0.08 m2K/W across the whole season and we recommend it for the next programme without change. For Trailhead Union 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.
