Gregory Arrio 22 vs Gregory Terros 25
Quick take: The Gregory Terros 25 costs $10 less; the Gregory Terros 25 carries more (25 vs 22 liters); the Gregory Arrio 22 is lighter (1.48 vs 1.82 lbs).
Which one to buy
$10 apart and one size each, so the question is what you want the pack to do. The Arrio 22 is the trail pack: an alloy frame, a suspended FreeSpan mesh back and a hydration sleeve at 1.48 lbs. The Terros 25 is the tougher everyday bag: frameless, with a padded foam back, 3 L more, a 20 lb rating against the Arrio's 15 lb, and 500D x 600D recycled polyester over a 900D base, far heavier cloth than the Arrio's 210D nylon.
For hiking, the Arrio does more for $10. Gregory files the Terros under urban packs and its trail features are thin, with no hydration sleeve and no back ventilation, and it weighs 0.34 lb more despite having no frame. It's also new as of June 2026 with no track record.
The Terros makes sense if the pack will spend more time on a commute or in an airport than on a trail, where its fabric and higher load rating are the bigger assets. The Arrio's weak spots are its 15 lb ceiling and a webbing hipbelt with no pockets, and Gregory is clearing this generation through its outlet while the redesigned Arrio 20, 24 and 28 replace it, so confirm which one you're buying.
Gregory Arrio 22
For day hikers who want a frame, a ventilated back, and a bladder sleeve for $110, with day loads under 15 lb.
Gregory Terros 25
Best if it's mainly a commuter or travel bag that sees occasional short hikes, where heavy recycled polyester matters more than a frame.

Pros & cons
Gregory Arrio 22
- ✓An alloy frame and FreeSpan suspended mesh back at a $109.95 list price, $60 under the Zulu 24 LT.
- ✓1.48 lb is light for a framed, ventilated daypack.
- ✓Hydration sleeve as standard.
- ✓Same lifetime warranty as Gregory's expedition packs.
- ✓Panel-loading zippered main compartment opens wide for easy access.
- ✗One size, with no torso adjustment.
- ✗No hipbelt pockets: the hipbelt is removable webbing.
- ✗This generation is being cleared through Gregory's outlet below its $109.95 list price, and the newer Arrio 20/24/28 are a different design, so check which version a listing is.
- ✗Only 15 lbs of rated carry, so it suits light day loads rather than full winter kits.
Gregory Terros 25
- ✓One of the cheapest current Gregory packs, $10 under the Arrio 22 and $20 under the Kiro 24.
- ✓500D x 600D polyester body over a 900D base is far heavier cloth than the 210D on Gregory's lighter daypacks.
- ✓Fully recycled fabric with a PFAS-free C0 DWR.
- ✓Three sizes, 20 to 28 L, at $89.95 to $109.95.
- ✓Lifetime warranty applies, the same as on the $370 Baltoro.
- ✗Frameless, so the 20 lb ceiling is a hard limit, even though it tops the framed Arrio's 15 lb.
- ✗Padded foam back without ventilation, where the Arrio gets FreeSpan suspended mesh and the Zulu LT gets VaporSpan.
- ✗Gregory lists it under urban backpacks, so trail features are thin.
- ✗New in June 2026 with no track record.
- ✗1.82 lb is heavier than the equally frameless Kiro 24 at 1.54 lb, despite the Terros being the simpler pack.
Gregory Arrio 22 vs Gregory Terros 25: common questions
Is the Terros 25 a real hiking pack like the Arrio 22?▾
It's rated to 20 lb with a C0 DWR like Gregory's hiking daypacks, but Gregory files it under urban packs. It has no hydration sleeve or ventilated back, so the Arrio 22 is the better trail choice for light loads, though the Arrio is rated to only 15 lb.
Which of the two is more durable?▾
On fabric alone, the Terros 25: its 500D x 600D polyester body and 900D base are much heavier cloth than the Arrio's 210D nylon with 420D. Both carry Gregory's lifetime warranty if something fails.
