Comfort
The Eja 58 is built to provide lightweight comfort without sacrificing support on longer treks. At the core of its design is the AirSpeed™ suspended mesh back panel, which creates a tensioned, trampoline-style fit that lifts the pack off your back for continuous airflow and reduced sweat—ideal for warm or high-output hiking. The harness and hipbelt are shaped for a women’s-specific fit, with just enough padding to provide cushioning and load support without adding unnecessary weight. The Eja 58 maintains comfort best with loads up to about 30–35 lbs, making it a great choice for lightweight and minimalist multi-day trips.
Weight & Packing
The Osprey Eja 58 is a lightweight yet well-equipped pack, weighing approximately 2 lbs 13 oz, depending on size. It features a top-loading design with a removable floating lid, which can be swapped for the included FlapJacket™ cover to save weight when going minimalist. Key features include the AirSpeed™ suspended mesh back panel for ventilation, a women’s-specific harness and hipbelt, dual access side water bottle pockets, a large front stretch mesh pocket, and dual zippered hipbelt pockets for quick-access items. Additional touches like stow-on-the-go trekking pole attachments, removable sleeping pad straps, and an internal hydration sleeve make the Eja 58 highly functional without compromising its ultralight appeal.
Price
The Eja 58 is priced at $280, placing it in the mid-to-premium range for ultralight women’s backpacks. While it’s more expensive than budget or entry-level options, the Eja 58 is a strong value for hikers who want a lightweight design without giving up comfort, ventilation, or essential features. The price reflects its quality materials, women’s-specific fit, and thoughtful balance of performance and packability for multi-day adventures.
