KOALA2.0 Phone Tether for Via Ferratas – Is It the Best Phone Tether? A Complete Guide for Via Ferrata Enthusiasts

Smartphones have become a standard piece of equipment on via ferratas. We use them for navigation, checking the weather forecast, taking photos and videos, and calling for help in an emergency. Mountain safety organisations and experts emphasise that in highly exposed terrain, every item you carry should be properly secured against being dropped, just like the rest of your climbing equipment. That is why a phone tether for via ferratas can be such an important piece of gear. Via ferrata equipment guides regularly mention a phone as something worth keeping accessible rather than buried deep inside your backpack. At the same time, it needs to be properly secured against accidentally slipping out of your hand. This is why more and more people use phone tethers on via ferratas, allowing them to take photos and record videos without worrying about losing their device. On a via ferrata, your phone can be used for taking photos, recording videos, checking maps, monitoring the weather forecast and staying in touch with others. The problem begins when you need — or simply want — to use it in exposed terrain. That is why more people are searching for solutions using phrases such as phone tether for via ferrata, how to secure a phone in the mountains or how to avoid losing your phone while hiking. In our opinion, there is one clear answer: KOALA2.0.

It is an ideal phone tether for via ferratas.

Phone tether for via ferratas – why is KOALA2.0 such a good choice?

Just a few years ago, many people would leave their phone at a mountain hut, in the car or buried deep inside their backpack. Today, that is difficult to imagine. Our phones are with us almost all the time. On a via ferrata, a smartphone can serve as:

  • a camera,
  • a video camera,
  • a navigation device,
  • a source of weather information,
  • a way to call for help or contact others when necessary,
  • and sometimes a GPS tracking device.

The more challenging and spectacular the via ferrata, the more tempting it is to capture the views. At the same time, exposed terrain can make you reluctant to take your phone out at all. This is where a phone tether for via ferratas comes in.

How can you avoid losing your phone in the mountains?

This is a question almost everyone asks when starting their via ferrata adventure. There are three common solutions:

  1. Keeping your phone inside a backpack or waist pack.
  2. Keeping your phone in a trouser pocket.
  3. Securing your phone with a tether.

The first option is relatively safe for the phone itself, but taking it out while on a via ferrata can be awkward and risky. A waist pack keeps the phone within easy reach, but it still does not prevent you from dropping it while taking it out or using it. The second option makes the phone easily accessible, but many people have discovered that a phone can fall out of a pocket while climbing — even when the pocket can be closed. The third option — using the KOALA2.0 phone tether — is, in our opinion, the best compromise between security and convenience. By fitting your phone with the KOALA tether and attaching it to your waist pack, backpack hip belt or clothing, you can keep your phone secured while using it. If it slips out of your hand, the tether prevents it from falling far below or smashing against the ground.

How to choose a phone tether for a via ferrata

There are dozens of phone tethers available on the market. Most of them, however, have been designed primarily for everyday use around town. There are neck straps, for example, which simply are not comfortable for many sports — and certainly not ideal for via ferratas. A via ferrata is a completely different environment. You have to deal with:

  • sweat,
  • dust,
  • rocks,
  • often intense sunlight,
  • constant tension and pulling,
  • frequent one-handed use of your phone.

In these conditions, reliability matters. That is exactly why the KOALA2.0 phone tether is becoming increasingly popular among climbers, outdoor photographers and via ferrata enthusiasts.

KOALA2.0 – a phone tether for demanding via ferrata users

KOALA2.0 does not rely on traditional glued-on or add-on adapters.

Instead, it uses a silicone harness that wraps securely around the phone. It is made from high-quality material and works with many different smartphone models without requiring anything to be permanently attached to the device.

This makes it a highly versatile solution. Changing your phone usually does not mean you need to replace your tether. Its design means that even if you switch to a larger or smaller phone, or to a model with two or three camera lenses, the harness can usually still be fitted correctly. That is a major advantage. In practice, you are investing in one phone tether that can potentially serve you for many years. Its universal design also means that different members of the family can use the same tether with different phones, depending on their needs. It is also worth highlighting that the manufacturer provides a lifetime warranty, something that is extremely rare nowadays. For us, this says a lot about the quality of the KOALA tether. Active users particularly appreciate the KOALA2.0 phone tether for via ferratas because:

  • you do not need to buy a dedicated phone case,
  • you do not need to glue anything to your phone,
  • it does not block the charging ports,
  • you do not have to worry about an adhesive adapter coming loose after several months of use.

Do you really need a phone tether for via ferratas?

Our answer is: YES. Firstly, modern smartphones are expensive. Secondly, they often contain valuable photos, documents, contacts and access credentials. Thirdly, losing your phone while travelling can easily ruin an entire holiday.

KOALA2.0 allows you to use your smartphone without constantly worrying about dropping it. And when you consider the overall cost of a mountain trip, the tether may very well turn out to be one of its least expensive pieces of equipment. 😉

Phone photography and phone tethers on via ferratas

One of the main reasons we take our phones onto via ferratas is photography. The views can be spectacular.

With the KOALA2.0 via ferrata phone tether, you can take photos or record videos without worrying that your phone will disappear into the abyss. And remember: a falling phone is not only at risk of being destroyed — it can also injure someone below.

Securing your phone on a via ferrata is not just about another gadget

Many beginners consider a phone tether an unnecessary accessory. “I never needed one before.” “I’ve never dropped my phone.” “I won’t use my phone while climbing.” “It’s too expensive.” Our experience suggests otherwise. Just as a helmet protects your head and a rain cover protects your backpack from the rain, a phone tether protects your smartphone from the consequences of accidentally dropping it. Of course, a phone tether is not part of the equipment responsible for your climbing safety. However, a phone can slip out of someone’s hand while there are other people directly below, possibly looking upwards. Situations like this can and do happen.

How much does a via ferrata phone tether cost?

At first glance, the price of the KOALA2.0 tether may seem relatively high.

But is it really expensive protection when you consider: the price of your smartphone, the potentially priceless contents stored on it, the overall cost of your trip, the cost of your outdoor equipment, or even the price of a meal while travelling? Losing or damaging your phone can end up costing considerably more — and it can certainly affect the mood of your trip. Seen from that perspective, a reliable phone tether may actually be one of the least expensive items you buy for peace of mind. It is also important to remember that changing your phone does NOT necessarily mean buying a new tether, as is often the case with screen protectors or phone cases.

Why KOALA2.0 is a great choice for active travellers

Via ferrata accessories – what should you take with you?

Basic via ferrata equipment includes:

  • a helmet,
  • a harness,
  • a via ferrata set,
  • gloves,
  • a phone tether — in our opinion, a useful accessory both for convenience and for preventing your phone from being dropped.

Why do we use the KOALA2.0 phone tether ourselves?

In our experience, KOALA2.0 is one of the most practical accessories you can take on a via ferrata. We know this from our own experience. In fact, the reason KOALA2.0 is available in Europe is closely connected to our own search for a reliable way to secure a smartphone while climbing via ferratas. We had previously tested other solutions, but they often proved unreliable — either because of their design or because of poor manufacturing quality. When pulled sharply or caught on something, some of these tethers simply broke. KOALA2.0 was the solution that finally met our expectations, and thanks to SQUIRRELGEAR, the tether is now available within the EU.

Another feature that matters to us is how quickly the phone harness can be fitted and removed. When the phone no longer needs additional protection, the harness can be taken off and stored away quickly and easily.
