40mm MAGNETIC DOG COLLAR

The Conor's Adventure 40mm magnetic dog collar is designed for medium and large dog breeds. It combines premium materials, outstanding durability and practical everyday functionality in a lightweight, comfortable design.

It is made from 40mm polyester webbing, a lightweight aircraft-grade aluminium D-ring for leash attachment and an original FIDLOCK® magnetic buckle. Every Conor's Adventure collar is sewn with reinforced safety stitching, the same type of stitching used in professional climbing, search and rescue and military equipment.

The polyester webbing is highly resistant to heavy loads, mechanical wear and UV exposure. Although the webbing gets wet, the polyester fibres do not absorb water, allowing the collar to dry quickly. Thanks to the 2mm thick polyester webbing, the collar will not stretch under load, as polyester is significantly less elastic than many other materials.

The D-ring for leash attachment is made from aircraft-grade aluminium. It is lightweight, corrosion-resistant and designed to withstand extremely high loads. According to the manufacturer, the 40mm D-ring has a static load rating of up to 225kg. During our own testing, it successfully withstood a static load of 140kg without any damage.

The FIDLOCK® magnetic buckle is manufactured from high-quality engineering plastic and stainless steel. The integrated magnet simply guides the buckle into the correct position, making fastening quick and intuitive. The magnet does not keep the collar closed. Once engaged, the buckle is mechanically locked and will not open under load. For additional security, it can also be secured with a safety lock to prevent accidental release.

According to the manufacturer, the FIDLOCK® buckle has a static load rating of 70kg. During our own testing, however, it withstood a static load of 140kg without any damage.

KEY FEATURES:

  • Original FIDLOCK® magnetic buckle.
  • Quick and intuitive magnetic fastening.
  • High-quality, strong, reliable and lightweight aircraft-grade aluminium D-ring.
  • Additional D-ring for attaching an ID tag.
  • Most collar components are made from materials designed for use in the most demanding conditions (climbing, military, search and rescue, etc.).
  • Built to withstand exceptionally high loads.
  • Modern and innovative design.
  • Designed and handmade in Slovenia.
  • 1-year warranty.

Customise your collar with a range of accessories. UPGRADE to an original COBRA® ProStyle buckle, add a handle, or personalise it with a Velcro patch or embroidery.

Add-on

Original AustriAlpin COBRA® ProStyle buckle

For an additional charge, you can upgrade your collar with the original COBRA® ProStyle buckle manufactured by the Austrian company AustriAlpin. This professional-grade aluminium buckle is certified for climbing applications and withstands loads of up to 18kN (1,800kg). Despite its exceptional strength, it weighs only approximately 67g.

The patented locking mechanism allows the buckle to be opened only by pressing both side release buttons simultaneously. If the buckle is under load, or if only one button is pressed, it cannot be opened.

COBRA® ProStyle buckles are normally available in black. Other colours may occasionally be available upon request, so please contact us for current availability.

Add-on

40mm Personalised Velcro Patch

When ordering a 40mm collar, you can personalise it with your dog's name. The patch can include your dog's name, a phone number* or any other text of your choice. Various thread colours and patch background options are available.

The patch consists of two parts: the hook (rough side) and the loop (soft side). The hook side is sewn onto the personalised patch, while the loop side is sewn onto the collar. The patch can also be used on any equipment fitted with compatible loop Velcro.

NOTE*
For very small dogs with a smaller neck circumference, the available space on the collar is limited, which may restrict the maximum length of the personalised patch.

For any special requests, please contact us.

Add-on

40mm Handle

The 40mm collar handle allows you to gain quick control of your dog whenever needed. It is particularly practical for long-haired breeds, where the collar may be hidden beneath the coat. For larger breeds, it also provides a comfortable way to hold the dog close while walking beside you. It is especially popular among search and rescue dog handlers.

Made from durable polyester webbing, the handle is resistant to mechanical wear and UV exposure. The material is soft, comfortable to hold and will not cut into your hand. It is available for all 40mm collars in every colour, with optional colour combinations (for example, a black collar with a blue handle).

Handle dimensions*:

  • Length: 8cm, width: 2.4cm (sizes M, L and XL).
  • Length: 6cm, width: 2.4cm (size S).

COLLAR SIZE

Measure your dog's neck circumference using a flexible measuring tape. We recommend measuring the neck snugly, without leaving extra space, especially when choosing smaller sizes. All Conor's Adventure collars are adjustable.

  • XS 25cm – 36cm (made to order)
  • S 33cm – 43cm
  • M 41cm – 51cm
  • L 48cm – 58cm
  • XL 56cm – 66cm (made to order)

HANDLE: When a handle is added, the adjustment range is slightly reduced due to the additional attachment points. The available size ranges are:

  • S 40cm – 43cm
  • S/M 39cm – 44cm
  • M 44cm – 51cm
  • L 48cm – 58cm
  • XL 56cm – 66cm (made to order)

If required, we can customise both the collar size and the handle length to suit your dog's needs.

PERSONALISED PATCH: When a 15cm personalised Velcro patch is added, the adjustment range is slightly reduced due to the space required for the Velcro panel. The available size ranges are:

  • S 38cm – 43cm
  • M 42cm – 51cm
  • L 48cm – 58cm
  • XL 56cm – 66cm (made to order)

CARE

The collar can be hand washed or machine washed at 30–40°C. We recommend placing it inside a laundry bag before washing. Allow it to air dry naturally in the shade. Do not tumble dry or expose the collar to high temperatures.

FAQ

A magnetic FIDLOCK® buckle... is it really safe?

A perfectly reasonable question. In fact, most people ask exactly the same thing the first time they see it in action: "Is my dog's safety really dependent on a magnet?" The answer is no. The magnet's only purpose is to assist with closing the buckle quickly and easily. The magnet does NOT keep the collar closed.

What if the FIDLOCK® buckle loses its magnetic strength?

According to the German manufacturer FIDLOCK®, this should not happen under normal use. The magnetic strength could only be affected if the buckle is exposed to high temperatures for an extended period (for example, when washed above 60°C). Based on the manufacturer's testing, salt water is not an issue either. However, after exposure to seawater, we always recommend rinsing the collar thoroughly with fresh water to help prolong the lifespan of the materials and metal components.

Can I exchange the collar for a different size?

If the collar is unused, undamaged and shows no signs of wear, we will happily exchange it for a smaller or larger size at any time.
If you discover later that the collar is slightly too large, we can also shorten it (rather than replace it) without any problem. We always do our best to find the most practical solution for our customers.

What is aircraft-grade aluminium?

Aircraft-grade aluminium, also known as duralumin, is an aluminium alloy containing copper, magnesium and manganese. It combines low weight with exceptional strength and excellent corrosion resistance. Thanks to its outstanding mechanical properties, it is widely used in the aerospace industry as well as in many other demanding applications.

I am extremely satisfied with the collar. The quality of craftsmanship is truly at a very high level – all the stitching is precise and the materials feel robust and high-quality. At the same time, the collar is comfortable for the dog and suitable for everyday use.

The Fidlock buckle is an excellent solution, as it allows quick and easy fastening and unfastening, while also providing a feeling of safety and reliability. I am also very satisfied with the handle, which is practical and especially useful in situations where you need to quickly grab the dog or keep it under greater control.

Another big advantage is the willingness to accommodate individual wishes and customizations, as it is easy to discuss details and receive a product that truly suits both you and your dog.

Overall, this is a premium collar where attention to detail and quality craftsmanship are clearly visible. I would not hesitate to buy it again and would gladly recommend it to others. :) I highly recommend it!!

Tina 18/09/2025

The collar is really amazing! I already ordered a second one. It’s high-quality, durable, easy to use, and beautiful to look at… On top of that, the team is very friendly and always willing to help! Highly recommended ❤️

Gašper 23/03/2025

I recommend this collar to everyone who values quality and wants only the best for their dog. It is extremely durable, aesthetically refined, and definitely the best collar I have purchased so far. The COBRA buckle allows for easier and faster fastening, which is a big advantage with our Husky’s long coat. I was also impressed by the handle option that you can choose when placing your order.
A sincere thank you as well to Pija for her quick responsiveness and kindness!

Vesna 15/01/2025

We bought the collars already in 2022 and they are still the same today. We also added handles and name patches, that is also unchanged. The buckle still works flawlessly. In addition, Mrs. Pija took time for us and our complicating about colors and patches, without any visible bad mood ???? Keep it up!

Katja 08/01/2025

I accidentally bought the collar and leash at the vet more than half a year ago. I was looking for a product suitable for larger breeds (American Bulldog), that will handle our strong female dog. The product is very high quality and compact. I especially like the additional handle on the collar, which often comes in handy for extra control of our dog. The buckle on the collar is innovative and incomparably better than classic ones. The fact that the product is made in Slovenia is an additional plus. We are very satisfied. No other collar and leash come into consideration anymore!!
