BUYER'S GUIDE / FIT SYSTEMS
How to read a performance fit before the first workout.
Start with movement range and fabric recovery. Size labels are only useful once you know what the garment is designed to hold, release and protect.
Map the pressure points
Waistbands, armholes and seams should be judged under the movement that loads them. A secure running fit may feel restrictive in a mobility session; a soft studio layer may lose structure at tempo pace.
