Pros & cons
Osprey Exos 58
- ✓The classic gateway ultralight — AT thru-hiker surveys have ranked the Exos among the most-carried packs for years running.
- ✓The AirSpeed trampoline back is the only real ventilation in the sub-3-lb class, and sweaty-back refugees notice immediately.
- ✓The current generation's adjustable torso fixed the old fixed-size gamble, making online sizing much safer.
- ✓It carries 35 lbs with a composure frameless cottage packs can't match, per constant r/Ultralight comparisons.
- ✓The removable lid strips 4+ ounces for weekend loads, with a flap jacket underneath to keep things clean.
- ✓Osprey's lifetime All Mighty Guarantee is a genuine advantage over cottage packs' 1-2 year coverage.
- ✓REI availability means you can try sizes on in person — rare in this weight class.
- ✓The 100D ripstop has proven far more durable than its spec-sheet denier suggests over multi-thousand-mile reports.
- ✗No hipbelt pockets on a pack this popular remains baffling — nearly every long reviewer lists it first.
- ✗The exposed side mesh pockets snag and tear on brush; they're the best-documented wear point.
- ✗The stock hipbelt is thin, and loads at the 40 lb ceiling telegraph straight to the iliac crest.
- ✗The trampoline frame bows into the packbag, so a BV500 rides high and awkward.
- ✗The stretchy shove-it pocket sags when loaded with wet gear.
- ✗The frame creaks for some users after dusty miles — a known quirk Osprey service lubes rather than fixes.
- ✗At $260 it's within $40 of true cottage packs (Circuit, Kakwa) that weigh half a pound less.
- ✗Ultralight purists find the hanging-lid-and-straps aesthetic fussy compared to clean roll-tops.
Osprey Renn 65
- ✓$205 is the cheapest way into Osprey's AirSpeed suspended mesh in a women's fit.
- ✓3.6 lb is lighter than the Ariel 65 by over a pound despite being a fraction of the price.
- ✓The hipbelt spans 26 to 48 inches, a much wider range than most women's packs accommodate.
- ✓600D polyester is heavy but hard-wearing, which suits a pack likely to be learned on.
- ✓A 50 L sibling shares the same suspension for shorter trips.
- ✓One-size adjustable construction avoids the risk of buying the wrong frame size online.
- ✓An extended-fit option is offered, which is rare at this price.
- ✓Osprey's All Mighty Guarantee applies at the entry level too.
- ✗OutdoorGearLab measured just 40 L in the main compartment against 65 L advertised, the largest discrepancy in the Osprey line.
- ✗No manufacturer max-load figure is published, and the entry-level frame is the least capable in the range.
- ✗600D polyester is the heaviest fabric Osprey uses for the protection it gives.
- ✗The feature set is basic next to the Ariel, with no Fit-on-the-Fly adjustment.
- ✗One-size construction means less precise fit than the Ariel's two frame sizes.
- ✗A rain cover is confirmed on the men's Rook but not stated for the Renn.
- ✗Only two volumes offered.
- ✗Bear-canister fit is not stated for this model.
