Ortlieb Atrack BP Test waterproof backpack for bikepacking
Ortlieb Atrack BP Test: waterproof backpack for bikepacking and outdoor adventures

Note – this post is advertising: I requested the Ortlieb Atrack BP from ORTLIEB Sportartikel GmbH as a test copy. I was then given the bikepacking backpack for a test.

Ortlieb Atrack BP in the test

With the Bikepacking backpack Ortlieb goes new ways: The access is via the back and the backpack is thus opened like a travel bag. The zipper extends over the entire back area and beyond. Access via the large zipper ensures the convenience and clarity of a travel bag.

The BP stands for Bikepacking. Compared to the normal Ortlieb Atrack, Ortlieb gives the waterproof bikepacking bike backpack some bike specific adjustments:

  • Wide hip fins vs. detachable hip belt
  • Slim silhouette
  • Helmet mount
  • Volume: 45, 35, 25L vs 25L
  • Other special features

In addition, the Atrack BP brings the carrying system and features of an outdoor backpack. This gives you convenient access to your gear even when the backpack is fully loaded. (clarity and accessibility)

  • Adjustable carrying system with good ventilation

Organization & Equipment

How much volume does the Ortlieb Bikepacking backpack offer? How much equipment really fits in and what about accessibility?

With 25 liters of volume, the Atrack BP offers plenty of space for a bikepacking backpack. This makes the Atrack particularly suitable for extended tours, for example an alpine cross and also for commuting. Thus, the Ortlieb Atrack BP can be counted among the large bike backpacks.

Organizational possibilities inside:

Let’s take a close look at the organization options and compartments inside.

The heart of the Atrack BP is the large main compartment: The inner compartment offers the most space. In addition, equipment or even a laptop can be secured with a lashing strap.

Inside there are 2 zippered pockets on each side (1x large pocket and 1 x small pocket on each side). There is one large and one small zippered pocket on each side. Equipment that you want to have quick access to can be stored in these side zipped pockets: Wallet, smartphone, bike multitool, arm warmers and leg warmers or the bike rainwear.

A hydration bladder can also be positioned in one of the large inner pockets. The Atrack backpack has a waterproof passage and an attachment system for the hydration bladder tube. The official accessory for this is the Atrack Hydration System. You can find out exactly how it works in the “Accessories” section further down in the Atrack review.

At the top of the interior compartment is a small hook that can be used to store such things as keys or other small accessories for instant access.

Organizational possibilities outside

Even with the organization options on the outside of the Atrack BP, Ortlieb goes new ways and has come up with clever details: On the outside of the bikepacking backpack, the 5 orange straps are immediately noticeable. At first glance, the concept seems complex, but then it is immediately learned:

All straps can be pulled together. This allows the outdoor backpack to be unzipped and remains nice and slim even when fully loaded. This is especially important if you use it as a bike backpack and are racing through the undergrowth on forest paths and trails. After all, you don’t want to get stuck on branches left and right unnecessarily 😉

The orange belts have other functions as well:

Long Orange strap from bottom to top (vertical): Serves as helmet attachment and makes the backpack easier to put on and close. As I said: If you want to guarantee full waterproofness, you have to close the TIZIP zipper tightly.

Four orange straps with attachment hooks: Ortlieb calls the straps Daisy Chains. I would say these are practical attachment slings. There you can loop in further accessories. As an example Ortlieb shows the attachment of longboards, skis and hiking poles. I have not yet fixed particularly large and heavy objects to the fastening straps but I can confirm the reliability of the straps. A quite fully loaded backpack can also be lifted up by the straps without something tearing out.

Very typical and very practical for an outdoor backpack: On the left and right side there are slots with large mesh pockets. In them you can store e.g. water bottles, flipflops or even a foldable sleeping pad. The pockets are already large and deep. This allows the equipment to find a secure hold in the pockets. For added security, items can be tied down with one of the orange daisy chain straps.

This fits in

In numbers: 25 liters! What does that mean exactly? Twenty-five liters of volume is easily enough for the luggage on a Trans-Alp, for a weekend trip and even more so for an Overnighter.

For extended and month-long backpacking trips, the Atrack 35 litre or the Atrack 45 litre i.e. the Atrack variants without bike adaptations are more recommended.

Carrying comfort of the Ortlieb Atrack BP

Does the Ortlieb Bikepackng backpack sit comfortably and stably on your back? What about ventilation and climate at the back?

Ventilation and climate

With four large mesh pads, the Atrack BP rests on your back: Two elongated pads on top, and two smaller resting areas on the bottom. When the Atrack BP is put on, you quickly notice that the ventilation concept works: The four pads keep the bikepacking backpack comfortably away from your back.

Ortlieb Atrack BP Experience Pads

Air can circulate well, which provides a comfortable climate at the back. Of course, the pads, as well as the shoulder straps lie against the body and during sweaty rides you will always sweat more with a backpack, so without a backpack.

Overall the ventilation works really well – even with a loaded pack.

Comfort and stability

There are numerous adjustment options for the right fit and comfort:

Ortlieb Atrack BP Adjustment Size

The padded shoulder straps can each be adjusted in length via a load control strap by simply pulling. The shoulder straps are wide and are also made of mesh padding. This makes the backpack comfortable to wear even when fully loaded. On longer rides, the wide shoulder straps don’t cut in. The wearing feeling remains pleasant.

For an additional secure fit, the Ortlieb Atrack BP can be fixed with the chest strap and the hip straps.

The back system is also adjustable. More precisely, the back system (large back padding) can be adjusted in height. The carrying system here has markings between and XL. The outdoor backpack can thus also be adapted to different body sizes. Especially practical if you want to carry the backpack of e.g. the smaller friend for a certain distance. The markings make it easier to adjust and reset the backpack.

According to Ortlieb, the Atrack BP is a fully waterproof bike backpack according to IP67. This corresponds to complete dust-tightness and protection against short-term submersion up to 1 metre for up to 30 minutes. Important: The waterproof TIZIP zipper must be completely closed. Once the zipper is closed, you have to apply some force again. Then the zipper engages clearly noticeable in its final position – the waterproofness is now guaranteed.

Protection from dirt: A nice side effect of wearing the Atrack BP is the protection from dirt: If a lot of dirt is swirled on your back while mountain biking or bikepacking, it simply lands on the Atrack backpack. The zipper is located at the back and thus remains free of dirt. Once you have reached your destination, you can simply rinse the waterproof backpack generously and it will be clean again. Even if you don’t have access to water when camping, for example, the access at the back remains free of dirt.


Inspiziert one the quality of the backpack quite exactly, so I can think of nothing but praise: The backpack exudes quality from top to bottom. Of course, the Atrack BP was also manufactured in Germany (Made in Germany).

PS21R (PU-coated nylon fabric, PVC free) is used. In order to ensure waterproofness, the material was joined together using a high-frequency welding process. In contrast to glued or sewn fabrics, absolute waterproofness can be guaranteed in this way. The composite of different material layers appears to be cast from a single mould.


What extras are already integrated in the Atrack BP? What expansion possibilities are there through available accessories?

The Atrack BP has an integrated helmet holder in the form of a toggle. Such a holder is more than practical and a must if you want to use a bike backpack off the bike e.g. for hiking, shopping or just walking through town: When not in use, the holder is tiny. If it is needed, the rather bulky helmet is safely stowed.

Due to a missing helmet holder I once forgot my old bicycle helmet at the train station in Frankfurt. Until I could organize a spare helmet again, some days passed and I was meanwhile without helmet in the Danish hinterland on the bicycle on the way. Since then: bike backpack always with helmet holder, please 😉

The range of functions of the Atrack backpack can be extended with separately available accessories. I have not yet tested the accessories in practice. Since it seems quite practical in principle, I present the Atrack accessory as well:

Ortlieb Atrack hydration bladder

If you want to upgrade the Atrack BP with a hydration system, then the hydration bladder from the Atrack Hydration System can be found in one of the large inner pockets on the right. There, the hydration bladder is then positioned directly next to the feed-through for the drinking tube. The bikepacking backpack has a waterproof grommet for the drinking tube.

The drinking tube can be fixed directly to the right carrying strap. If you do not need a hydration bladder, then the passage is closed with a plug provided for this purpose and the waterproofness remains guaranteed.

Atrack Attachment Kit for Gear

With the Attachment Kit for Gear, the intended use of the Outdoor Backpack can be expanded. With these straps and attachments, even large and unwieldy outdoor gear such as trekking poles, skateboard, snowboard, snowshoes, skis or tripod can be attached to the outside of the Atrack BP and Ortlieb Atrack.
