Halcyon Studio Portugal: Trail Running Programme Colour and Appearance Review
Halcyon Studio is a Portugal-based brand whose trail running programme is one of its most demanding programmes. Appearance decides whether a customer reorders. This review tracks how the moisture-wicking polyester single jersey holds its colour and surface through wear and washing for Halcyon Studio.

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.

Colour measurement
Shade was measured instrumentally against the approved standard and scored by eye under retail lighting. Both methods stayed inside the agreed tolerance across every lot.
Wash and light fastness
Colour fastness to washing reached grade 4-5 and light fastness met the requirement for long off-road efforts on mixed terrain. Shade change after repeated washing was not visible to the panel.

Surface appearance
Pilling, snagging and shine were assessed after wear. No shine developed under mud, grit, wind and rapid weather changes, which is where friction normally shows first on this product type.
Shade continuity
Production was consolidated into controlled dye lots so repeat orders match. Retained standards are held for two years to support reordering without new development.

“The report gave us numbers we could put in front of our retail partners without any argument.” — Halcyon Studio Technical Team

Verdict and recommendation
Appearance was maintained through wear and washing, and the moisture-wicking polyester single jersey is approved for repeat orders against the retained shade standard. 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.
