Osprey Exos 38L backpack

Does the backpack not squeak due to the back ventilation system, as I´ve noticed on other brands that have this system??, and what size should I take for a man of 1m70??

Answer of Gizem

I purchased the backpack about 15 months ago, used it a few times, and it has not made any squeaking sounds. I am 176 cm tall, and the L/XL size fits me comfortably

Ideal buyer profiles

The Ultralight Thru-Hiker

This hiker prioritizes minimizing weight for long-distance treks and fast-paced adventures. They meticulously select gear that offers maximum function for the lowest possible weight, enabling them to cover more ground with less effort.

The Osprey Exos 38L is an excellent match due to its ultralight design and AirSpeed™ ventilated backpanel, which enhances comfort and reduces fatigue on long trails. The Exoform™ hipbelt and ErgoPull closure provide a snug fit and optimal load transfer, ensuring stability even with a full pack.

The Adventurer

This individual seeks high-performance gear that aligns with their environmental values. They prioritize products made from sustainable materials and by brands committed to responsible manufacturing practices.

This backpack is made from 100% recycled, Bluesign® approved 100D nylon ripstop with a PFC/PFAS-free DWR finish. This construction offers durability and weather resistance while meeting high environmental and ethical standards, making it an ideal choice for the eco-conscious hiker.

The Organized Weekend Backpacker

This person enjoys weekend or multi-day hiking trips and values gear that keeps them organized on the trail. They need a pack with enough capacity for essential gear and smart pocketing to keep items accessible.

With a 41-liter capacity, this pack is well-sized for weekend trips. It features dual zippered hipbelt pockets, a front stretch mesh pocket, and dual-access side pockets for easy organization. The internal hydration sleeve ensures water is always within reach, supporting a well-planned adventure.

Competitive features

When evaluating the Osprey Exos 38L Backpack for men, it's important to consider its specific design focus. This pack is engineered for experienced backpackers who prioritize minimizing weight for streamlined overnight or weekend trips. Its feature set, including the AirSpeed suspension and Stow-on-the-Go pole attachment, is tailored for performance on the trail.

Where it excels

The Exos 38L is designed as a lightweight specialist, making it an excellent choice for experienced hikers focused on fast-and-light trips where every gram counts. It features the AirSpeed suspension system, which is engineered to provide significant ventilation, enhancing comfort during strenuous activity in warmer conditions. Constructed from 100% recycled materials, it appeals to environmentally conscious users without compromising on performance-oriented features. Features like the removable floating lid with an integrated FlapJacket offer versatility, allowing users to further reduce weight for minimalist setups.

Consider alternatives if...

For travelers needing a single pack that converts for urban and travel use, a more versatile travel-specific pack like the Osprey Farpoint or Sojourn series might be a better fit, as they often include features not found on a dedicated hiking pack. Beginner backpackers or those who prefer a more structured, all-purpose pack might find models with different suspension systems or more organizational features to be more accommodating than this ultralight-focused design.

Verdict

The Osprey Exos 38L is a purpose-built pack that excels in its niche: lightweight backpacking for experienced users. Its design prioritizes comfort at a low weight, ventilation, and essential trail features over all-purpose versatility or massive capacity. While it stands out for streamlined trips, those needing a travel-hybrid pack, more storage for extended journeys, or a more forgiving entry-level option should explore the alternatives. Its construction from recycled materials is a significant benefit for the eco-conscious adventurer.
