Gregory Arrio Review

Publication date: 06 Jul 2026

The Arrio from Gregory is a really great bag. For a long time, I’ve been wanting a ventilated day pack, but found that most brands stop ventilating as the pack volume decreases. The Arrio solves this problem! With a VaporSpan back panel, the mesh means breathing easy even on tough hikes. I especially appreciated the springy back and shoulder straps when it was rainy and I was sweaty, because that is a combo that never feels nice with a backpack on.

My boyfriend and I got the 20L and 22L versions and took them with us on a trip with friends to the Dolomites last autumn. They held up really well, especially stuffed full of layers, and the ventilation also helped us stay comfortable by keeping the pack’s general weight off of us when it was misty. The packs are decked out with small comforts that make it feel like a long-distance, larger volume pack, while still staying small and perfect for short trips.

Testing the Arrio

We took a couple of the Gregory Arrio’s with us to the Dolomites last autumn and were really excited about it. While it’s always fun to swap out the bigger long-distance packs for daypacks, day packs normally come without some of the features that make long-distance packs so comfortable. But they incorporated those into the Arrio, which is what made it our first choice.

The Arrio has a flexible hipbelt that gives just enough support without going overboard. Because the pack range is between 20-30L, you won’t be carrying anything too heavy in this (max. suggested carry weight is ~10kg). Which means that a flexible hip belt that moves with you is key. I found it to be really comfortable.

It is also, as I’ve mentioned, a fantastic ventilated day pack. The VaporSpan back panel works well and felt light when I was carrying it. Likewise, the shoulder straps are ventilated, too, with perforated foam and open mesh. It feels almost bouncy!

When we were out on the trails, we stuffed these packs as full as we could with picnic supplies, layers, water, and even gear for a cheeky mountain hut stay one night. The design definitely withstood our testing.

About Gregory

Gregory is an American company that’s been around since the 1970’s. Named after its founder, Wayne Gregory, the company’s calling card is their suspension systems that keep the packs lightweight, no matter how much you’ve thrown in them. Gregory is committed to creating packs that last a lifetime, so they’ve built a customized Life Cycle Assessment (LCA) tool to calculate the environmental footprint of the energy used and the impact across the entire product lifecycle.

About the Arrio

The Gregory Arrio is a step up from your average day pack. If you’re looking for something that will keep up with all your packing demands and still stay as comfortable as possible, this is it. I’ve tried a lot of day packs, and the Arrio just feels like it’s got all of the ventilation and mesh that you can put in a smaller bag like this without it feeling overboard. Any more and I worry it would feel like too much, but they’ve hit the nail on the head, so to say.

The Arrio is unisex and has three sizes, 20L, 22L, and 30L. I bought the 22L, but I tested out all of the sizes at the store and they have a very similar fit. There are also four color options that are lovely shades of grey, blue, yellow and black for a subdued profile that won’t stand out super starkly when you’re in nature.

The pack has one main pocket that closes with a quick-pull drawcord, and then is covered with a flip top that has a zippered pocket. There are also a pair of side stretch mesh pockets, and a hydration sleeve in case you want to add a reservoir. Finally, the pack also has a few different loops for attachments, so you can really deck it out with all of your hiking accessories. Gone are the days of the sagging school backpack on trail!

One thing that also came in handy was the included raincover. We ran into a few drizzly days since it was autumn when we went, and I think we were in a bit of denial about the possibility of precipitation, so we didn’t pack any raincovers of our own. Needless to say, having those available was definitely a lifesaver when the skies opened up.

Conclusion

I’ll be keeping this as my main day-hiking bag for a long time to come, since it really does everything I need, and more than I thought possible from such a small bag.
