Nice pack

This pack has done everything I've needed it for. It's very comfortable and has plenty of space for a day or two. The straps are easily adjustable and the pocket layout is well thought-out. I cant wait to get back out there and put it to more use.

comfortable and spacious

Extremely comfortable due to the various ways that it can be adjusted. It has room to spare for everything that I need for an 8 day walking tour on which I will carry all my clothing etc. rather than paying for transport from accommodation to accommodation.

Perfect Day Pack

This is the perfect size for a long day hike. I loved having the hydration system readily available while hiking. I'm more likely to stay properly hydrated when I don't have to stop and take out my water bottle. Lots of great pockets, pouches and storage. Also very comfortable and adjustable. I got the mineral yellow color and it's super cute, too!

99% perfect!

This is almost the perfect day pack. I had a different brand but it was lacking in so many ways. Gregory has thought of almost everything. Only thing I’d like to see is a bigger outside zip pocket for snacks! I love the hanging clip for the hydration bladder, and that the hose detaches up top instead of way down by the outlet. Hip belt pockets fit my phone and all the little stuff. All the straps were perfectly comfortable even with a tank top on, no rubbing on a 10 mile hike.

Great multipurpose pack

Looked forever for a pack that I could take on day hikes but also use as a daily gym bag as well as a personal item on a plane. Technically this pack is too long for a personal item, but so far I haven’t had any issues or been asked to check it. I needed a pack that had hydration storage for hikes. The bonus is that I can use that same storage for my laptop when I travel. Organization is also really important to me and this pack has sufficient pockets and spaces for that.

Love this pack!

This is a great pack! I needed a new pack and after checking out several brands and models, I ultimately chose this one for an upcoming inn-to-inn hiking trip to Scotland. I used it for 8 days, 103 miles, and it was everything I had been looking for and needed. The integrated hydration system is fantastic, easy to care for and to fill on the fly. The fit is great, the shoulder straps and hip belt very comfortable.

No back sweat!

I absolutely love this pack. It’s a little bigger than what I actually need for a daypack, but this is so comfortable I use it for every hike. The back panel is a dream and keeps your back from sweating. I wish Gregory would incorporate this excellent back panel on all their packs. Love my Swift but the Juno rules for hot weather outings.

Great Backpack / Day pack

The Juno 30 was extremely comfortable for my wife hiking all day in the Rockies and fit all the items needed for a 12 + hour day.

I used this hiking more than 30 miles on day hikes in Banff. The frame makes this very comfortable and helps you not overheat when hiking. It also helped keep my water and food cool, since the heat from my back wasn’t transferring to those items. All of the pockets are perfect for storing snacks and other necessities. The hydration bladder is easy to fill and clean. The size was perfect for me. I am 5’6”, 125 lbs for reference.
