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.

Direct answer
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. — anonymous engineering note on library block EL·MB-510. Remake samples From 1 piece (typically 7–9 working days); bulk 150 pieces per style per colour.
Problem
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.
Hardest moment
Soft pile vs memory: a plusher fleece felt right in hand but bagged faster at the knee; a tighter knee looked sharp standing and bound on the stair. Ease and recovery had to be set as a pair.
Levers we locked
Knee ease
Knee curve and thigh ease graded so the pile was not asked to stretch past recovery.
Rise and crotch
Front rise and crotch curve reset so the seam stopped spiralling under stride.
Validation
- Sit, stair and walk wear trial
- Knee bagging review after a day-shape simulation
- Crotch seam alignment after movement
