Our ratings (out of 10)
1 to 10, compared with the whole market. Each says what it's based on. How we score
Weight
From maker's figures 7/10How much the empty rucksack adds to what you carry, as sold. 7: Better than most.
Osprey lists 1,290 g for the S/M (58 L), in the 1,000 to 1,499 g band. The L/XL (61 L) is 1,330 g.
Comfort with a full load
From reviews 8/10How well it carries a full camping load over a long day: hip belt, shoulder straps, back and how the weight sits. 8: Clearly better than most.
Four sources carried 11 to 16 kg and all liked the suspended mesh back. OutdoorGearLab (Colorado Trail, comfort 8 of 10) says its testers found it comfortable up to about 16 kg and less comfortable beyond that. Switchback Travel calls 11 to 16 kg the pack's sweet spot, after a multi-night Cascades trek and other long trips. BetterTrail (4 of 5) carried up to about 16 kg on several short backpacking trips and found it more comfortable than any other lightweight pack it had tried. CleverHiker (one review of the Exos 58 and the women's Eja 58) rates comfort 4.6 of 5 in a test at 13.6 kg, which we count as 5, although it notes the load rides away from the spine. Osprey rates the pack 14 to 16 kg.
Durability
From reviews 6/10How well the fabric, zips, buckles and frame hold up over seasons of use. 6: A bit better than average.
Three wear reports, all short, on thin 100D recycled nylon. Switchback Travel's team used it on a multi-night Cascades trek, the Tahoe Rim Trail and Appalachian Trail sections and saw only light scuffs on the base; it rates the build about average, and the previous model was sliced on granite. BetterTrail (one week) saw a few snags on the mesh pockets and rates durability 2.5 of 5, counted as 2 because a half rounds down. We Are Explorers (free sample, kept) saw no wear after 9 days and two flights as checked baggage. Section Hiker (free sample) warns the pocket mesh is too weak for off-trail travel but reports no wear, so it is not counted.

In short
Good for
- Multi-night trips where the loaded pack stays under about 16 kg (Osprey rates it 14 to 16 kg)
- Walkers who want a framed pack under 1.3 kg (S/M) with a ventilated back, two zipped hip-belt pockets and a front stretch pocket
- Warm-weather walking: reviewers praise the airflow of the suspended mesh back (OutdoorGearLab, Switchback Travel, We Are Explorers)
Strengths
- 1,290 g (S/M) for a framed 58 L pack: a 4 mm perimeter frame holds a suspended mesh back panel off your back
- Four sources found it comfortable with 11 to 16 kg (OutdoorGearLab, Switchback Travel, BetterTrail, CleverHiker)
- Two sizes (S/M 58 L, L/XL 61 L) and about 10 cm of ladder torso adjustment
- Two zipped hip-belt pockets, a front stretch pocket, two zipped lid pockets, and side pockets that open from the top and the side
- The lid comes off and the built-in FlapJacket cover closes the bag; the sleeping-pad straps are removable
Weaknesses
- Thin 100D recycled nylon: BetterTrail got snags on the mesh pockets in a week and Section Hiker advises staying on trails
- Hip-belt pockets are small: a phone barely fits or does not fit (OutdoorGearLab, Section Hiker, We Are Explorers)
- The crossing side compression straps make tall bottles awkward to take out and put back (OutdoorGearLab, Section Hiker, Hawkins Hikes)
- Rated for 14 to 16 kg only, and OutdoorGearLab's testers found it less comfortable above about 16 kg
- Top-loading only, with no sleeping-bag zip or side zip into the main bag (Switchback Travel, Hawkins Hikes)
- No rain cover in the box (BetterTrail)
