Halcyon Studio Finland: Trail Running Programme Field Test Report
Halcyon Studio is a Finland-based brand whose trail running programme is one of its most demanding programmes. Halcyon Studio runs its trail running programme across Finland 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 moisture-wicking polyester single jersey.
Halcyon Studio: Moisture-Wicking Polyester Single Jersey in use during long off-road efforts on mixed terrain
Evaluation background
The programme covers trail shorts, technical tees and light shells, used for long off-road efforts on mixed terrain. The environment is mud, grit, wind and rapid weather changes and the requirement written into the brief was abrasion resistance with fast drying after stream crossings. 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 long off-road efforts on mixed terrain and laundered under the same domestic conditions, so the only real variable was wear.
Conditions covered
The programme ran through mud, grit, wind and rapid weather changes. 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 AATCC 195.
What users reported
Participants logged comfort, drying behaviour and any irritation. The recurring comment was that the moisture-wicking polyester single jersey stayed comfortable at the point where abrasion resistance with fast drying after stream crossings would normally be lost.

Verdict and recommendation
Field testing confirmed the laboratory picture. The moisture-wicking polyester single jersey held its moisture management class 4-5 across the whole season and we recommend it for the next programme without change. For Halcyon Studio the practical next steps are to keep the current specification for the repeat, retain the shade standard, and issue AATCC 195 results with every lot so any claim can be supported with data.
