Osprey Exos 58 Review

Osprey Exos 58 Review

Need an ultralight pack that doesn’t sacrifice support or features? In this Osprey Exos 58 review, we’ll explore why this popular men’s backpacking pack is a top pick among thru-hikers and minimalist trekkers who still want structure and comfort.

The Osprey Exos 58 is a 58-liter ultralight backpack designed for long-distance trips, fastpacking, and weight-conscious hikers. Weighing just over 2.5 pounds, it offers an ideal blend of minimal weight and solid carrying performance. Unlike some ultralight competitors, the Exos 58 includes an internal frame, ventilated AirSpeed back panel, and well-padded hipbelt and shoulder straps for comfort over long distances.

The pack features a floating lid (removable), large stretch mesh front pocket, dual side pockets, trekking pole attachments, and integrated compression straps. If you want to go even lighter, the lid can be removed and replaced with the included integrated FlapJacket cover.

Comparisons

Osprey Exos 58 vs Gregory Focal 58

The Gregory Focal 58 is one of the Exos’s closest competitors in the ultralight framed pack category. Both are built for long-distance hiking and offer excellent ventilation with mesh-backed suspension systems. The Focal tends to feel a bit sturdier when carrying heavier loads thanks to its more structured hipbelt and frame. However, the Osprey Exos 58 excels in overall airflow and feels less restrictive while moving. If you’re after a pack with a softer ride and better bounce control, the Exos delivers a more breathable and fluid hiking experience.

Osprey Exos 58 vs Zpacks Arc Haul Ultra 60

The Arc Haul Ultra 60 from Zpacks is in a different league when it comes to weight, coming in nearly a full pound lighter than the Osprey Exos 58. It’s also fully customizable and ideal for dialed-in ultralight setups. That said, the Arc Haul requires careful packing, has a more delicate feel, and lacks the support that framed packs like the Exos provide. The Exos 58 stands out for its comfort, airflow, and versatility—making it a smarter choice for hikers who want to balance weight with convenience and durability without breaking the bank.
