Rated 4 out of 5 by from Fantastic… but it needs a taller bottle sleeve Love this pack for day hikes or an overnight with my fiancé wearing it. Fantastic suspension, but the bottle sleeve needs to be a little deeper.

Rated 5 out of 5 by from Perfect Pack I purchased this pack about a month ago and have used it on all my hikes (3-7 miles). I love it so much! I had REI's Flash 22 but wanted something with a bit more structure, a trampoline back, and no hip belt. After much searching, I came across the Arrio 18 and it checks all the boxes. I do wish there was another small interior pocket, but I have more than enough space. I also wish there were more color choices, and in brighter shades, as I like to be more visible with my pack.

Rated 4 out of 5 by from Nice but not the style for me Seems to be a high quality item, but I don’t think I like the style of the top opening, with the flap compartment, and drawstring to get to the main compartment, so I sent it back. Also I found the drawstring slider difficult to operate, compared to others I have on backpacks and jackets

Rated 4 out of 5 by from Solid pack, with a few caveats I live near several trails, so I often do shorter loops (5-7 miles) several times per month, just for exercise and fresh air. But my Citro 24L is overkill for that, so I wanted something a bit smaller, and I'm a huge fan of Gregory. This pack is super lightweight, the pocket on the brain is a good size, and I like the additional side zippered pocket, since I never carry two bottles on the outside. However, there's a couple minor dings that prevented 5 stars. One is the really small opening to the main compartment. It's really narrow, making it difficult to get anything further down. And the trampoline back is nice, but it's sort of recessed into the pack, so when it's flat on your back, it doesn't provide as much airflow as the arched ones. A pocket underneath the brain would have been nice, as well as maybe gear loops for trekking poles, but if you want all those additional features, just get a bigger pack. However, if you want a minimalist type pack that's super light, this is great.

Rated 5 out of 5 by from Perfect size Perfect size for a day hike and it looks good too. I can't wait to hike the Rim to Rim trail in the Grand Canyon with it!
Date published: 2021-04-23
Rated 5 out of 5 by from Great small daypack! This is a great backpack for anyone wanting a small daypack with minimal organization, good materials, and a really comfortable fit. One thing I can say about Gregory harnesses is that they tend to fit my upper body the best since I am relatively slim with broad shoulders.

Rated 5 out of 5 by from This is your pack. Picked up this pack with the intention of having a light daypack that could still hold a solid amount of stuff that I like to carry with me on hikes, and this has plenty of room! I'm glad I went with the 18, as it's still small enough but has a good amount of storage for all of the things I take. Thanks, Gregory!

Rated 5 out of 5 by from Great daypack! This is the pack I reach for for day hikes! I love the structure this pack provides and the frame and mesh back keep me from getting too sweaty! Perfect size for a layer or two and trail snacks.

Size Guide

Gregory Men's Packs

Gregory backpacking packs are available in a size range. Please check the PRODUCT FEATURES and / or SPECIFICATIONS for the torso range measurements of each size of a pack. The steps below are a guide for measuring your torso size.

The hipbelts on Gregory backpacking packs are adjustable to fit a range of sizes. A simple rule of thumb is that the ideal distance between the ends of the hipbelt pads after tightening should be 3 to 5 inches. However, the most important criteria are that the hipbelt wraps clear over the side of your body and that it rests 1 inch above your iliac crest. This allows proper load transfer to your skeletal structure, which maximizes comfort and minimizes energy expenditure.


HOW to MEASURE TORSO SIZE
1. Put your chin to your chest and feel for the big bone protruding on your neck at the top of your spine. That's the C7 vertebra.

2. Feel your hip bone, the top part of this is your iliac crest. Find the spot on your back that is level with the top of this crest.

3. Have someone measure the distance between these two points, following the contours of your spine.
