Rab Exion 55 Review: The Ultimate Pack for Every Adventure

First Impressions of the Rab Exion 55

For many years, I have been a loyal fan of the premium British brand Rab. Their clothing and gear continue to improve in quality and variety each year. I often wear the Rab Capacitor Hoody so frequently that people have started to comment on it, and my wife even has to remind me to change into something else occasionally. The sleeping bags from Rab are also highly regarded, but this is the first time I’ve had the opportunity to test one of their backpacks in the field. This particular model, the Exion 55, is part of a new product category for Rab, named after Scottish climber and alpinist Rab Carrington.

The Exion 55 comes in various sizes, and I opted for the 55-liter version. Packs with compression straps offer great versatility, making them ideal for long day hikes, especially during spring and fall when waterproof jackets, rain pants, fleeces, and puffers might be necessary but too warm to wear from the trailhead. Additionally, they can easily accommodate everything needed for a lightweight overnight or multi-day adventure, including a sleeping bag, camping mat, backpacking tent, and stove.

I was excited to put the Exion 55 through its paces and compare it to some of the most popular daypacks and hiking backpacks on the market. Let me say, I wasn’t disappointed. However, I’ll share more details about what I loved and what I found less appealing.

Design and Materials

One notable feature of the Exion series is the availability of different sizes and styles, including versions specifically designed for women with an ND (narrow dimension) fit. This includes a 55L version tailored for a more comfortable fit.

A key element of the Exion design is Rab’s V-TRAX carry system, which features an adjustable harness mounted on a lightweight 6mm aluminum frame. The dual-density foam ensures even weight distribution, providing cushioned support where needed while minimizing contact with the back to reduce rubbing and sweating.

The hipbelt includes generous pockets and is tightened by pulling the straps forward, which is more effective than adjusting the belt to the side. The pack also features large mesh side pouches perfect for water bottles, as well as a dedicated compartment for a hydration bladder with a hang loop and hose portals.

The Exion 55 is incredibly versatile, with compression straps allowing users to adjust the size and volume of the pack based on the adventure. An extendable hood adds an extra 5L of storage space and includes three zipped pockets—two external and one internal. There are also loops and toggles on the exterior for carrying trekking poles and ice axes.

One standout feature is the large U-shaped front zip, which allows easy access to the main compartment without having to empty everything out. A large mesh pouch on the front is ideal for storing wet or dry waterproof gear. However, it's worth noting that the pack may be vulnerable to theft during public transport due to its accessibility.

Performance on the Trails

I have used the Rab Exion 55 during big day walks along the South West Coast Path and for multi-day wild camping trips on Dartmoor while researching walking routes for a new book. It has performed exceptionally well in both roles—as a large daypack and a modest-sized overnight hiking pack that encourages careful packing and enhances the enjoyment of each outing.

The carry capacity is easy to adjust using a combination of compression straps, mesh pouches, and the capacious hood. Despite the additional storage, the hood never bumped against my head, even when fully loaded, which is a common issue with other packs I've used.

On day walks, the Exion stays close to my body, and when I need to load it up for longer adventures, it comfortably fits my Jetboil stove, MSR Hubba Hubba tent, Therm-a-Rest camping mat, sleeping bag, and enough food and supplies for several days of exploring hills, tors, and moors.

The V-TRAX carry system allows for excellent breathability, while the full-contact wrap-around harness and hip wings provide strong support. Adjusting the waist belt is straightforward, helping to position the load for efficient hiking. The fully adjustable sternum strap completes the setup quickly.

Water bottles stored in the angled side pockets are easily accessible without removing the pack, and I made good use of the hydration reservoir compartment, ensuring balanced and efficient water carrying.

Small details like the emergency whistle on the chest strap and emergency instructions inside the hood are thoughtful touches. However, I would have liked to see a Recco reflector included for safety. Another point of note is that the pack doesn’t appear to be made with any recycled materials. Overall, the Exion 55 is an excellent choice for all kinds of hiking adventures and is built to last, making me eager to take it on many more journeys.
