Osprey Eja 58 Women’s Backpack: Lightweight Comfort for Multi-Day Backpacking

I’ve been using the Osprey Eja 58 as my go-to backpacking pack for over 5 years, and it’s honestly one of my favorite pieces of gear. It’s lighter than most packs I’ve carried, yet the weight sits perfectly on my hips so I don’t feel like I’m lugging a ton. I’ve taken it on many trips to Joshua Tree, including my thru-hike on the California Riding & Hiking Trail, a backpacking trip to Havasupai, and countless other adventures, and it’s never let me down.

Why I Love the Eja 58

What I love most is the airflow in the back; the AirSpeed™ suspension keeps me cool even on long, hot days. The removable brain is a game-changer for ultralight packing, and the outside pockets are big enough to fit my Tiger Wall UL2 tent, while the main compartment easily holds a full-size bear can. Honestly, after 5 years, this pack still feels like new, and I wouldn’t hesitate to recommend it.

Designed for Women: The Eja vs. the Exos

The Eja is the women’s version of Osprey’s ultralight line, while the Exos is the men’s version. The Eja 58 is perfect when every ounce counts, but you still need a supportive, reliable backpack for multi-day trips. It’s made from 100% recycled materials, and the fit, ventilation, and comfort make it easy to carry heavy loads without feeling weighed down.

Key Features & Personal Tips

One of the things I love most about the Eja 58 is how thoughtfully it’s designed. Everything has a purpose, and you can tell it was made by people who actually spend time on the trail. Here are some of my favorite features and little tips from using it over the years:

• The top lid (or “brain”) is removable if you’re going ultralight, but it also has great zippered pockets for quick-access items when you do keep it on.
• There’s a FlapJacket cover underneath, so you can still close it securely without the lid; super handy for shorter trips.
• The front stretch mesh pocket is perfect for stuffing layers, a rain jacket, or anything damp.
• The side pockets are roomy enough for my Tiger Wall UL2 tent poles or large bottles.
• The hydration sleeve inside fits a water bladder, or, my personal trail trick, a pack of tortillas (they stay flat and safe there).
• The hipbelt pockets are ideal for snacks or your phone, so you don’t have to stop to dig around.
• I love that there are tons of attachment points and loops for carabiners. I clip my electrolyte bottles or hang random gear I need to dry.
• The Stow-on-the-Go loop that’s meant for trekking poles? It’s also perfect for holding a tripod if you bring a camera setup.
• The compression straps and removable sleeping pad straps make packing flexible; you can strip it down or load it up depending on the trip.
• And of course, the sternum strap whistle and solid construction give you peace of mind when you’re deep in the backcountry.

Comfort, Suspension & Fit

The Eja’s comfort is honestly what makes it my favorite pack. The AirSpeed™ suspension system gives you a ton of airflow between your back and the pack, which is a lifesaver on hot days. It also adjusts easily to your torso length, so you can fine-tune the fit.

Even when it’s fully loaded, the LightWire frame keeps the weight balanced, and the EXOFORM™ shoulder straps and hipbelt feel soft but supportive, with no weird pressure points after long days. I’ve done plenty of 10+ mile days with this pack and still felt great at camp.

Durability & Materials

After years of use, mine still looks almost new. The fabric is made from recycled high-tenacity nylon with a PFC/PFAS-free water-resistant coating, so it holds up well to dust, brush, and the occasional scrape against rocks.
