Perfect ergonomics
Thanks to a major development of the Julius-K9 IDC®-Powerharness the chest strap forwards the power lines of the leash with almost no breakage
Breathable, skin friendly inner liner 
eco-texNormally we don't pay enough attention to these great properties.The OECO-TEX® material is manufactured by the highest standards of human clothing manufactures.
Heavy duty buckles 
The high-quality buckles of an Julius-K9 IDC®-Powerharness are permanently tested and checked. This careful attention worth especially in wintertime: these buckles work perfectly and don't break even in frosty weather.
Reflective edges and chest strap 
One of the important functions of an Julius-K9 IDC®-Powerharness is that it works well also as a visibility vest. The grey line of the chest strap and the edges of the harness are made of reflective materials, so the walking dog is visible in the dark even from a bigger distance.
Torch holder 
The torch holder is with rubber, so it gives high stability, the torch can not slip out of the holder. It's useful for night walks too if we would to follow our dog. Thanks to the ergonomic design you don't have to worry that your dog can be blocked because of the loops. The torch holder was made of high quality German materials. It allows to use sidebags simultanously.
It's essential for search and rescue dogs and for every service dogs which are working in the dark.
Sidebag fixing option 
Sidebags are available in 3L and 4L versions for the bigger Powerharness sizes from 0 to 4. A smaller Julius-K9 IDC® Universal sidebag is also available since 2013. With a 250 ccm capacity it's ideal to carry personal documents, vaccination papers, cell-phone and dog treats.
Handle lock with new snaps 
The new handle fixing option of the Julius-K9 IDC®-Powerharness allows 4 different variations. You can fix only the steel ring, only the handle, both of them or none of them. With these you can minimize the dog's chance of being blocked. It's really important especially for hunting dogs, search- and rescue dogs.
Note: If the dog is blocked by the bushes at a place that is not visible, the Julius-K9 IDC®-Powerharness allows free movement backwards, so the dog can escape.

The Velcro mounting safety lock was developed in 2004 by Julius-K9® especially for service dogs. This practical accessory increases by 60 kg the load capacity of the buckle under the chest. Ensures safe use even in case of damaged (chewed) buckles. It's used by police service dog unit of London since 2013.
