DEUTER ATTACK 16L RUCKSACK REVIEW

September 30, 2026

Deuter is one of the big names in high-end rucksacks for adventures, and has been making their “Attack” bag series for the last 20 years. Having recently teamed up with the Athertons, Deuter is showing that they intended the Attack to support some seriously gnarly days out.

I’ve always hated riding with anything bigger than a small hydropack on my back, but this 16-litre pack from Deuter has been changing that opinion.

ABOUT THE DEUTER ATTACK 16L PACK

The Attack 16 is not just a standard hiker’s pack that Deuter has strapped to everyone’s favourite maniac in an attempt to brand it as a “biking pack”. Instead, it is a purpose-built and well-considered mountain bike rucksack to support some big days out in the saddle in gnarly terrain.

Deuter focused on producing the Attack with sustainability in mind. As a result, all of the materials used – including the RE ZRO back protector – are socially and environmentally sustainable, with the pack receiving the Green Button and Bluesign certifications. There are no PFAS used, with an eco-friendly DWR coating in place instead.

On top of the standard features you would hope to see on any rucksack, there are a few genuinely useful mountain bike-specific features that separate the Attack from other traditional packs. Starting with the obvious, the Attack features an integrated, removable CE Level 2 RE ZRO back protector, which provides lightweight and breathable impact protection. RE ZRO uses a fully recyclable and biodegradable TPE to provide flexible protection with an eco-boost.

Deuter also equips the Attack 16L with a “Carrying Guard” to allow you to comfortably carry your bike on your back without damaging the straps, offering improved comfort for the long hike-a-bikes.

External storage has been covered too: chords and clips at the top and bottom of the exterior can be used to securely fasten knee pads, helmets or other bulky items that you want easy access to. An integrated rain cover keeps your essentials dry when the weather turns.

On the inside, you’ve got a 16L capacity that is given tidy features to keep things organized. The Attack pack features a pump attachment, tool organiser and an easy-access fleece-lined goggle pocket at the top of the bag. There is space inside for up to a 3L hydration bladder, supporting big days out in the backcountry.

The Airstripes breathable shoulder straps and back panel help to keep the pack comfortable and stable in use. Stability and fit security is bolstered with numerous adjustment and stabilising straps to get it locked down tight. The waist strap is fastened with both a standard clip and Velcro strap to further ensure comfort and this all-important stability.

Deuter offers the Attack 16-liter pack in a choice of three colors, with a retail price of £200 / €220. For riders looking for different capacities, Deuter have packs from eight to 22 liters in their Attack series.

THE DIRT

Two things often bother me when wearing large-capacity packs on the longer remote rides. Firstly, I typically find big packs wobble about and give you that uneasy, shaky feeling when you’re trying to descend. Secondly, I find that the biggest threat to back injuries is not rocks on the ground, but the square-edged objects sitting inside your pack. The Deuter Attack 16 solves both of these problems for me.

The Attack 16 does an excellent job of hugging tightly to your back and remaining stable down some of the rougher descents. Deuter has cut no corners, with large, double-secured, padded waist straps and a smaller but crucial sternum strap. The external compression straps ensure things stay nice and snug.

The integrated back protection is almost a no-brainer for riding packs, and the RE ZRO insert is an excellent lightweight and breathable option. It’s great that you can easily take the insert in and out to tailor the pack to the day ahead. No matter how light the protective insert is, nobody wants to carry around back protection on days when they don’t need it.

The breathability of the Deuter Attack 16 was also impressive. With a full pack on a long loop in heatwave temperatures, I found the Airstripes technology worked surprisingly well to keep my back relatively sweat-free all ride. And when the sweat did come, it didn’t feel stifling, with the airflow keeping temperatures down and helping with some evaporation.

The external storage was surprisingly secure. I mainly utilised the external cords to secure knee pads on extended ascents, but even when descending on some rough terrain, the things that I have strapped to the outside tended to remain there. The carry guards might lean slightly towards the gimmick side of things for riders who only very occasionally hike-a-bike. But if you frequently have the bike on the shoulders and take care to ensure the downtube actually sits on the abrasion resistant panels, I can see this being something that might improve the longevity of the pack and comfort of the rider.

My only real frustration with the Deuter Attack is the main storage compartment. The zips for the main section of the bag extend all the way to the bottom, which can make it frustrating to pack and use day-to-day. Often, I find myself wanting to quickly reach for my camera, only to find the whole pocket opening as the zips slip down to the bottom. This has its benefits, improving access to the large pocket and letting you take stuff from the bottom of the bag without turfing everything else out. But, I feel that if the zips were shallower, if there was some mechanism to stop the compartment from gaping open (such as side clips), it would be easier to use the bag quickly and pack items in on days when you have brought more kit than you should have.

At around £200, the Deuter Attack 16 is on the expensive side of riding packs, even in comparison to some other “high end” mountain bike-specific brands. However, I will say every penny of this £200 can be felt throughout the Attack 16. The high quality you would expect from this price tag is certainly present. The Attack 16 has become my primary rucksack for anything from big rides out in the fells to zipping from the pits to the side of a race stage with my camera.

The Wolf’s Last Word

Overall, the Deuter Attack 16 is an excellent product. Whilst the cost is high, it’s a pack that I often reach for, and it has been the perfect tool for some of my longer missions. It is always nice to see a pack that has been designed specifically with mountain biking in mind, and it really comes across when you’re using it in the hills. It is comfortable on long days out, secure on descents, and provides the peace of mind that your back is protected from the contents of your pack. It’s one of those products that makes you feel obliged to start planning some longer days out, just to give you the opportunity to use it.
