Direct answer
Failure modes we lock before PPS — not customer testimonials.
Anonymous only — no brand names or logos. Engineering notes show failure modes and levers; programme notes show market capsules. Full evidence also lives in the Evidence Center.
Engineering fixes
Problem → hardest trade-off → levers → validation → lock. Bound to evaluation-set blocks.
2-in-1 Training Short

Preventing Neck Stretch After Wash on Performance Tees

Travel Pants: Comfort, Wrinkle Control and a Clean Silhouette

Recovery Hoodies: Premium Handfeel Without Excess Bulk

Stopping Binding Roll and Armhole Gape on Training Tanks
After wash the crew binding rolled outward and the armhole opened on raise — buyers read that as a cheap tank before they read the GSM.

Stopping Waistband Roll and Leg-Opening Curl on Compression Shorts
On squat and lunge the waistband folded down and the leg opening curled — the short stopped compressing where the buyer needed it.

Controlling Knee Bagging and Crotch Twist on Fleece Joggers
After a day of wear the knee blew out into a bag and the crotch seam twisted — the jogger looked tired before the fleece hand did.
Knee bagging controlled · crotch curve revised · 150/colour path opened

Stopping Heat-Transfer Cracking After Wash on Performance Tees
The logo looked sharp on the first sample and cracked along the stretch after wash — a return driver buyers blame on the factory, not the film.
Crack path closed · film and press revised · 150/colour branding path opened

Reducing Inseam Chafe on Linerless Training Shorts
Without a liner, the inseam and the fabric face were the only things on the skin — and both chafed once the run went past an easy mile.
