GSM Sourcing Failure Risks

Getting the GSM wrong is the primary trigger for fit degradation and product returns.

Critical Fail
Sourcing low GSM fabric triggers Transparency (Sheerness) under gym lights.
Structural Fail
Low fabric density causes Bagging & Sagging around the knees and seat.
Performance Fail
Excessive GSM in tops traps sweat, causing Athlete Fatigue from water weight.
Comfort Fail
Heavy thermal weaves trap hot air, causing Heat Entrapment during intense training.
