How Men’s 2-in-1 Training Shorts Are Constructed

Outer shell

Lightweight MotionFlex shells prioritize mobility and low noise. Inseam and side split are locked to brand preference.

Liner

Supportive stretch jersey liner — length and recovery must be tested under squat and run motion.

Waistband & pockets

Encased elastic with drawcord is common. Zip or media pockets need placement tests with a phone.

Development path

Library 2-in-1 blocks accelerate first samples; custom opens new liner ratios and pocket geometry.
