Meridian Form Portugal: Yoga and Pilates Studio Programme Comfort and Fit Evaluation
Meridian Form is a Portugal-based brand whose yoga and pilates studio programme is one of its most demanding programmes. Performance data means nothing if the garment is uncomfortable. This evaluation covers how the recycled nylon interlock behaves on the body during yoga and pilates studio programme work.

Meridian Form: Recycled Nylon Interlock 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.

Fit assessment
Size sets were fitted on live models and on a fit form. Fabric extension was measured at the stress points so the pattern could be corrected before bulk cutting.
Movement testing
Wearers performed the movements specific to mat-based studio sessions and long holds while panel tension was observed. No restriction was reported and recovery between movements was immediate.

Next-to-skin comfort
Surface friction, hand and temperature sensation were scored by the panel. The fabric scored best where a soft hand with full coverage through every pose, which is the priority Meridian Form set for this product.
Fit retention
Garments were measured after five and twenty washes. Growth stayed within tolerance, so the fit approved in sampling is the fit the customer eventually receives.

Verdict and recommendation
Comfort and fit were confirmed in wear, and the recycled nylon interlock is approved for bulk with the current pattern. For Meridian Form 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.
