Built for versatility, the Exion 38 offers a stable carry, smart access features, and a durable build—perfect for long days on the trail or lightweight overnights.

Rab says: 

Fully featured with a clean, simple design, the Exion 38 is a highly versatile pack that takes you wherever you want to go, from demanding day hikes in any season to light summer overnights and wild camping. The adjustable V-TRAX™ carry system, with its thermoformed harness and dual densities of foam, ensures full contact with your back while delivering cushioning support where it’s needed and reduced bulk where it’s not. The result is a construction that keeps weight down, carries heavy loads well, and offers you instant comfort which endures over long distances. With an eye-catching embossed pattern and high-comfort, practical design, the Exion 38 is the perfect pack for unhurried miles on the trail.

Our Verdict

Rab’s Exion 38 is a versatile, feature-rich pack designed for demanding day hikes, light overnighters, and fast-moving adventures. Weighing 1,397 grams, it strikes a good balance between durability, comfort, and load-carrying efficiency.

The V-TRAX adjustable back system provides a close, stable fit, transferring weight effectively to the hips for better load distribution. The wraparound harness and supportive lumbar padding make for a comfortable carry, while the 3.5mm aluminium frame offers enough structure for heavier loads without feeling rigid.

The Exion 38 features a side zip for quick access to kit,, this is handy for reaching gear on the go, though it does mean careful packing is essential. The large front mesh pocket is a welcome addition, providing space for an extra layer or wet gear.

A slight downside is the compression straps over the side mesh pockets, which can make accessing water bottles less convenient. However, the overall fit, durability, and thoughtful storage options make this a strong choice for a comfortable and capable daypack.
