Why We Like The Eja 58L Backpack

From multi-unit backpacking trips in Denali National Park to minimalist thru-hikes on the PCT, the Osprey Eja 58 Backpack has all the space we need for lightweight trekking adventures. A removable daypack lets us take short, exploratory trips from our campsite, and plenty of mesh pockets and gear loops provide the capacity for maps, trekking poles, and snack stashes. An integrated rain cover protects gear on rainy afternoons, and compression straps keep everything under wraps. But where the Eja truly shines is in the form of the comfort it can provide. The combination of well-ventilated AirSpeed back panel and the light-yet-durable alloy frame brings a lot of breathability by dumping excess heat out the sides while we hike, and ExoForm covers the shoulder pads and waist-belt with mesh and energy gel for the ideal cushion needed over weeks or even months on the trail.

Size Bought
5` 8"
145 lbs

I bought the Eja in 58L and 48L with the intention of seeing which would suit my needs best for a summer bag that can accommodate a bear canister (up to bv500 size) or pack-raft. I am 5'8 with a ~17.5" torso and bought a small for both. Tldr; The 58 does have a lot more capacity but I found it to be uncomfortable and bulky so I'll definitely be returning it. The larger capacity led to awkward weight carry and I found I didn't need all the room it provided in the main compartment. I like the 48 initially and will keep that one to see how it performs on longer outings. For me, I noticed immediately that the 58L was less comfortable with the same contents and weight as the 48L. I tried loads of 15lbs up to 25lbs and essentially packed the packs with what I would bring for trips ranging from 2 to 4 nights including 2L of water and food I'd bring, plus a pack-raft that weighs >=2.8lbs. The frame on the 58L dug into my lower back and hips immediately once the pack weight was above 18lbs. The 48L didn't seem to have this problem. I wore each on short jaunts for about an hour. I also felt more pressure in the shoulders for the 58 no matter how I adjusted it. The back pressure point issue was an immediate deal breaker, though. I believe that because the 58L is slightly wider, the weight distribution falls beyond the edge of the curved frame causing it to dig in to the hip area. The 48L weight carry is more centered with less slop putting pressure on the area just outside my lumbar/hip area. I didn't notice a seam (common complaint) or pressure points on my back. 25lbs with the 48L was surprisingly comfortable, actually. I will try it out for a few multi mile hikes before leaving a review for that one.

Perfect Pack but No Side Pockets

I've put it through the wringer
True to size

This pack is almost completely perfect. It's super comfy and light, fits everything I need for backpacking, and the closures are amazing. However, no stretchy side pockets for a water bottle or gloves! I definitely miss that feature and it wouldn't add weight or bulk.

Great Lightweight Pack

I've used it once or twice and have initial impressions

The Eja is the best lightweight and fully functional pack out there. Wish more of the weight went on the hips.
