The optimised ergonomic shape and the breathable, skin-friendly inner lining make them very comfortable to wear. The optimal alignment of the chest strap distributes the pulling force directly to the chest. The infinitely adjustable waist strap is made of stable and pressure-tested safety belt quality and has a break-proof fastening buckle. The firmly stitched grab bar can also be fixed to the dishes by the Velcro surface from the mini-mini size up. Thanks to the neon yellow signal colour, the reflective chest strap and the fluorescent Julius K9-lettering, it offers more safety in the dark. The interchangeable Velcro stickers are available separately in many different versions.
