Solstice Athletics Ireland: Yoga and Pilates Studio Programme Colour and Appearance Review
Solstice Athletics is a Ireland-based brand whose yoga and pilates studio programme is one of its most demanding programmes. Appearance decides whether a customer reorders. This review tracks how the silver ion antibacterial knit holds its colour and surface through wear and washing for Solstice Athletics.

Solstice Athletics: Silver Ion Antibacterial Knit in use during mat-based studio sessions and long holds
Evaluation background
The programme covers leggings, crop tops and studio shorts, used for mat-based studio sessions and long holds. The environment is warm, humid studios with sustained low-load stretch and the requirement written into the brief was a soft hand with full coverage through every pose. 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 mat-based studio sessions and long holds. 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 warm, humid studios with sustained low-load stretch, 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.

Verdict and recommendation
Appearance was maintained through wear and washing, and the silver ion antibacterial knit is approved for repeat orders against the retained shade standard. For Solstice Athletics 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.
