INFINITY HARNESS – LONG 40mm

The Conor’s Adventure Infinity Long 40mm is an extended version of the Infinity Standard harness. It includes all the features of the Standard model and is designed for larger dogs. Suitable for both professional and recreational use. Its modular design, including various add-ons, allows for a wide range of applications.

It was developed in collaboration with one of the best orthopedic specialists in Slovenia – veterinarian Dr. Marko Novak, with the goal of ensuring minimal restriction while maintaining high comfort for the dog and ease of use for the handler.

The extension attaches to the Standard harness using aluminum components distributed across the back and belly. This transforms the 4-point harness into a 6-point harness, which is popular among dog owners whose pets can slip out of traditional 4-point designs. The 40mm harness extension includes an additional handle on the back, which can be folded away using a magnet. This is especially useful when lifting the dog over obstacles with both hands.

INTERCHANGEABLE CHEST SUPPORT

Depending on your intended use and your dog’s chest width, you can choose between two chest supports: NARROW and WIDE.

The narrow chest support is ideal for activities that require free movement of the shoulder joints or for dogs with a narrower chest.

The wider chest part is a great choice for protection training, professional work, or dogs with a broader chest. Use the sizing chart to help choose the right one.

FULLY ADJUSTABLE STRAPS

The harness can be adjusted in four different areas using extendable/retractable straps.

In addition to standard adjustments at the shoulders and (on the sides) at the ribs, many users will appreciate the option of adjusting the chest support – a unique feature of this harness. This prevents chafing under the armpits and allows maximum freedom of movement.

ONLY THE BEST MATERIALS

Like all Conor’s Adventure products, the Infinity harness is made of premium materials suitable for military and mountaineering use, and is reinforced with safety stitching.

Its outer layer is made of durable and scratch-resistant CORDURA®, while the interior features breathable and soft polyamide mesh. The straps are made of highly resistant polyamide, and the side closures use Fidlock® magnetic buckles.

All load-bearing components – D-rings and buckles on the shoulders and chest – are made from aircraft-grade aluminum, which withstands high loads and is corrosion-resistant. The handle and add-on loops are reinforced with Hyplon® synthetic rubber.

The standard version of the harness comes with Velcro already attached, but it can also be ordered without – in that case, please contact us.

BUCKLES

The Infinity Long harness features 6 buckles that secure it to the dog.

On the side straps, you’ll find FIDLOCK® magnetic buckles, made from high-quality plastic and stainless steel (INOX). The integrated magnet assists with easy fastening. The buckle is designed in such a way that it cannot be opened under load.

The harness can also be opened at the shoulders, which is a great solution for dogs that are afraid of having the harness pulled over their head. For this, two aircraft-grade aluminum buckles are provided – easy to use and securely closed even under tension.

D-RINGS AND HANDLE

The Long version of the harness features two 40mm D-rings and one 25mm D-ring on the back – all made from aircraft-grade aluminum.

The manufacturer guarantees that the 40mm D-ring holds up to 225 kg of static load, and the 25mm D-ring up to 345 kg. There is also an additional 25mm D-ring on the narrow chest section, designed for front leash attachment, which offers better control when pulling.

The back also includes a handle placed across the top for easy grabbing. It is covered with Hypalon® synthetic rubber to ensure a better grip. As mentioned, the Infinity Long 40mm also has an extra handle on the extension part, which can be stored away using a magnet.

WHAT ELSE CAN IT DO? - ADD-ONS

All Conor's Adventure Infinity harnesses are designed with the option to add various accessories. As already mentioned, the Infinity is the world's first modular harness, meaning you don't have to buy different harnesses. The Long version can easily be upgraded into a canicross harness.

Canicross Add-On

The canicross add-on is attached to the harness using aluminum components. Two clips (small carabiners) are connected to the back section (left and right), while two aluminum parts are attached to the belly straps, which are placed “at an angle.”

With the canicross add-on, it is especially important that the pulling forces are distributed differently (directed more backwards), which helps prevent the dog from being restricted while running or pulling. The extension is properly attached to the harness when it aligns almost in a straight line with the leash (see video or image).

WARNING: To use the canicross add-on, the extension must be removed from the harness. The canicross add-on is NOT USED with the extension but only with the STANDARD (short) harness.

Personalized Patches

Personalized Patch 40mm

When ordering the Conor's Adventure Infinity – Long harness, you can personalize it with your dog’s name. The patch can include the dog’s name, your phone number, or anything else. You can choose from different patch colors and backgrounds.

The patch consists of two parts: hook (rough) and loop (soft). The hook part is sewn onto the patch and the loop part onto the harness. You can use the patch anywhere Velcro (loop) is already installed.

For custom requests, please contact us.

Reflective Add-Ons

The Conor's Adventure Infinity harness intentionally does not include fixed reflectors, as we found through a survey with our followers and customers that many prefer the option of removable reflective add-ons.

The reflectors are made from CYFLECT® HONEYCOMB glow-in-the-dark tape that absorbs light and emits a greenish glow in the dark. The tape glows for about 10 minutes before needing to be “recharged.” You can do this by briefly exposing it to light (from a flashlight or phone).

When lit by car headlights, the tape acts as a highly visible reflector seen from at least 200 meters away.

The set includes six reflectors: 4 for the front part of the harness (2 wide and 2 narrow on the shoulders) and 2 larger ones for the back sides.

HARNESS SIZE

To choose the correct harness size, we need three measurements of your dog. These are: neck circumference (measured lower than for a collar), chest girth at the widest point, and chest length (see video). Measure your dog using a measuring tape or string. If you’re unsure about the size or need help – contact us and we’ll be happy to assist you. :)

CARE INSTRUCTIONS

Wash the harness with lukewarm water, scrub with a soft brush if needed, and let it air dry in the shade. Your dog can go into water with the harness without any issues. After swimming in salt water, we recommend rinsing the harness thoroughly. The harness can also be machine washed, but only at a temperature of up to 40 °C. To prevent potential damage to the harness and washing machine, we recommend using a laundry bag during washing.

FAQ

Is the harness suitable for car travel?

Our harness is not certified for car travel, as this would require every single component to be tested and certified to withstand a variety of forces. In principle, it can be used in the car to keep your dog secured on the back seat, but we still recommend transporting your dog in a crate specifically designed for car travel in the trunk.

FIDLOCK® magnetic buckle… but is it safe?

A perfectly reasonable question. Many people wonder the same when they see it for the first time. Is my dog’s safety really dependent on a magnet? The magnet’s function is only to “assist” with closing the collar. The magnet does NOT hold the collar together. If you're wondering how strong the buckle actually is, check out our blog post (How much weight can a leash clip and collar buckle hold?) and see for yourself that there's no need to worry. In a static load test, it withstood at least 140 kg (we ran out of weights after that).

What if the FIDLOCK® buckle loses its magnetism?

According to the data and guarantees from the German company FIDLOCK®, this should not happen—unless the buckle is exposed to high temperatures for an extended period (e.g. washing at over 60°C). Their testing also confirmed that salt water is not a problem. Nevertheless, we highly recommend rinsing the harness or buckle with fresh water if it comes into contact with salt water.

What is aircraft-grade aluminum?

Aircraft aluminum or duralumin is an alloy made of aluminum, copper, magnesium, and manganese. It is lightweight, strong, and corrosion-resistant. Duralumin is extremely hard, which is why it is also used in the aviation industry.

I use the Conor’s Adventure harness (Long model) both at work and at home, and it has truly exceeded my expectations.
First of all, I would highlight its modular design – the harness adapts perfectly to different needs and situations, which is a great advantage for everyday use. The craftsmanship is of a very high standard, the materials feel premium and durable, yet the harness remains lightweight.
The fit on the dog is excellent, which becomes especially noticeable during prolonged use – it does not restrict movement or cause overheating, which is very important to me. Even after an active day, there are no signs of discomfort.
Maintenance is another strong point. I clean the harness with a stiff brush, and the material shows no signs of damage or wear, confirming its durability.
Overall, I am extremely satisfied with this harness and can confidently recommend it to anyone looking for a high-quality, functional, and comfortable solution for their dog.

This is the kind of harness other manufacturers should take as a benchmark!

When choosing a harness for our female Kangal (around 60 kg), we were recommended this one. She is well socialized and completely non-aggressive, but she does have an issue with pulling on the leash. We had already tried slip collars, semi-slip collars, electronic collars, and haltis, but nothing really helped. We were almost ready to give up.
With this harness, the pulling force is nicely distributed across two points, as we use a leash with two clips. This makes the pulling much more manageable, and we also avoid sudden jerking movements that were harmful both for the dog and for the handler’s elbows and shoulders.
It feels like the harness is very comfortable for her – nothing bothers her, nothing presses or tightens (for the first time in her walking history). The quality is excellent, and the service is outstanding!
Thank you, Conor's Adventure!

Great harness. Quality stitching and attachment straps, magnetic buckles are easy to use and hold during the dog’s activity. I really like the modularity, especially the extended part with the additional handle, because on hikes in the mountains I can more easily help the dog over steeper sections.

The harness is top, really excellent quality and extremely well designed. We’ve had it for quite some time and had the chance to really test it well. The best thing about this harness and in general all Conor’s Adventure gear is that it can be adjusted to your dog. Since dogs are different and we have a Doberman for which we previously had a hard time finding the right size, we really appreciate this. 1000% recommend to everyone who wants only the best for their dogs!

Maja G. 09/11/2023

The harness exceeds all expectations! I use it as an aid for rehabilitation after front leg surgery and my dog wears it almost all day. It is strong enough to handle a 50kg load, the handle and support are in the right place so it doesn’t bother the dog when I lift him, and after a month not a single stitch has loosened nor has any strap come off. The magnetic buckles stay closed until I open them and they don’t open even while lying down. Since he doesn’t resist wearing the harness and is happy when I show it to him, I assume it is comfortable for him to wear. I am definitely more than satisfied with the purchase!
