Ergonomic, practical and convenient—this is the new innovative and height-adjustable SmartFlex system with 3-point ergonomics from McNeill. The back padding shapes itself to the contour of the back, and the three resting surfaces ensure a firm and ergonomically correct fit. At the same time, the resting surfaces ensure good ventilation of the back, even during prolonged wear. This innovative system was developed in close collaboration with physiotherapists Werner Krass and Anna Wallmen-Krass and was tested from a medical-ergonomic standpoint. Two McNeill satchel models have been developed with outstanding ergonomic features and a carrying system adapts perfectly to a child’s back - our satchels ERGO Light MOVE and ERGO Light COMPACT flex.
