The Stella Callie denim is a traditional 5-pocket motorcycle jeans with a stretch denim layer and stetch kevlar panels. The Kevlar panels on the seat and knees ensure high wear resistance. The triple stitched seams provide extra strength. The special ladies' slim fit and stretch parts ensure a high level of wearing comfort. The Bioflex protectors on the knees are flexible and practically invisible. This protection can possibly be expanded with the separately available BioFlex hip protectors.
