Steph Wetherell recommends the Rab Exion 55 – but notices one issue worth considering if you’re in a bigger body.

This Rab Exion 55 backpack is a well-designed and versatile bag with a plethora of pockets and an easy to adjust back system. If you are the kind of packer that likes everything to have a specific place, this might be the bag for you.

There are three pockets (two external, one internal) in the top of the pack alone that hold a combined 5 litres of kit. There are two mesh pockets on the shoulder straps that are a perfect for sunglasses or snacks, along with hip belt pockets, two side pockets, and a big stretch front stash pocket. The risk is forgetting which pocket you put something in. A U-shaped front zip allows you to access the main body of the pack from the front and made access much more straightforward.

Pole attachment points, an integrated raincover and a pouch/access for a water bladder are all there too. The fabric is durable and held up well on rough terrain, and the pack as a whole boasts 28% recycled content across fabric, frame and trim.

Rab Exion 55 review

The V-TRAX back system was straightforward to adjust with a hook and loop adjustable panel that slides up and down. The back itself offers a good amount of ventilation with the thermoformed harness and a nice amount of padding on the shoulder and hip belts. It’s a pull-forward adjustment for the hip belt, which made it easy to tighten to the right level.

They offer a ND (narrow dimension) specific fit for women and those of smaller frame, but it was too short in the back for me (43-48cm), so I opted for the unisex option instead. However, as someone with a large waist-to-hip ratio, I found the straight cut of the hip belt a little uncomfortable and I missed the curved hip belt that many women’s specific packs offer (not an issue when we tried the pack on a male hiking partner). This pack is a good choice for people who want a backpack with a lot of features and pockets but may not fit curvier people so well.
