Solstice Athletics Switzerland: Gym and Strength Training Line Wearer Panel Review
Solstice Athletics is a Switzerland-based brand whose gym and strength training line is one of its most demanding programmes. Twelve regular wearers scored the recycled nylon interlock over four weeks of resistance training and circuit work. Their brief was simple: report what you notice, and what you would change.
Solstice Athletics: Recycled Nylon Interlock in use during resistance training and circuit work
Evaluation background
The programme covers leggings, training tops and shorts, used for resistance training and circuit work. The environment is short bursts of high load against equipment surfaces and the requirement written into the brief was squat-proof coverage with recovery after repeated stretch. Fabric was selected on that basis rather than on price alone.

Panel composition
The panel mixed ages and experience levels, all training at least three times a week in short bursts of high load against equipment surfaces. Each wearer used one treated and one untreated garment so the comparison stayed honest.
Scoring method
Eight attributes were scored on a five-point scale after each session, with written comments collected weekly. Scores were averaged only after the panel finished, to avoid group influence.

Results
The treated fabric scored clearly higher on freshness, drying and comfort during resistance training and circuit work. The gap widened after week two, which is exactly when untreated garments start to draw complaints.
Verbatim feedback
The most repeated comment was that the garment still felt clean at the end of a long session. Criticism focused on colour range rather than performance, which is a design issue rather than a fabric one.

Verdict and recommendation
The panel confirmed the laboratory result. The recycled nylon interlock is worth the upgrade for any product worn more than once between washes. For Solstice Athletics the practical next steps are to keep the current specification for the repeat, retain the shade standard, and issue AATCC 183 results with every lot so any claim can be supported with data.
