Gregory Arrio 22

Gregory's frameless hiking daypack is the Kiro 24: 1.54 lb, a perforated foam back instead of a suspended mesh, a wrap-over harness, and a rain cover stowed under the lid. It comes in 20, 24 and 28 L and lists at $119.95.

Near the bottom of Gregory's price list sits the Terros, a June 2026 addition: a frameless 25 L pack in heavy recycled polyester with a padded back, sold in 20, 25 and 28 L sizes from $89.95 to $109.95. Gregory files it under urban packs but writes it up as trail-comfortable, and the 20 lb rating and C0 DWR put it in line with its hiking daypacks.

The Nano is Gregory's simple day pack. At 17 oz and $80 it is the value option in this group, with tough 450D recycled polyester panels most packs at the price skip.

The Citro is Gregory's hydration day pack and ships with a 3 L reservoir included. At 2.0 lb it is lighter than Osprey's equivalent Manta 24 by well over a pound, and $30 cheaper, while bundling a larger bladder.

The women's-fit Citro: 1.93 lb with a 3 L reservoir included and a 420D reinforced base, at $180. It matches the men's Citro on price while weighing marginally less and adding a tougher base fabric.

The Zulu 30 is Gregory's big day-hiker and light-overnighter, pairing a ventilated FreeFloat suspended mesh back with a pivoting hipbelt and an adjustable torso. The women's version is the Jade 28.
