A women’s pack that keeps you cool and dry during hot summer hikes.

The Gregory Women’s J 63 Backpack is made for weekends and multi-day hikes where heat can be an issue. The pack's ventilated, breathable harness and special CrossFlo suspension design allow heat and moisture to escape so you stay dry and comfortable while you hike.

With a maximum load recommendation of 40 pounds, the J 63 is perfect for everything from overnighters to extended weekend hikes. Gregory's CrossFlo suspension system is strong, simple, and lightweight. It also provides cooling airflow across your back to pull moisture and heat away. At the heart of the system is the wire X-Frame, which provides effective load transfer straight to your lumbar region and padded waist belt, where it can be carried most efficiently. The dynamic Yoke integrates the shoulder harness directly into the X-Frame, activating the suspension as the weight increases to balance the frame's flexibility. The back panel is made with a moisture-wicking, breathable mesh to transfer heat and moisture away from your body.

Access to the J 63's main compartment is made easy with a large, u-shaped zippered opening. A large zippered front pocket provides convenient storage for items that you'll need to get to through the course of your hike, such as lunch and rain gear. The pack also provides easy access to small items with dual waist belt pockets and a large dump pocket on the front of the pack, as well as a highly water-resistant top pocket with a waterproof zipper and sealed seams. And, speaking of waterproof, the J 63 comes with an integrated, color-matched rain cover to keep your gear safe and dry when an unexpected storm pops up.

Here's what others have to say...

Does anyone know if this could work as a carry-on on airplanes? Or, has anyone tried it?

Hey Deb,
It might not fit under the seat when it's fully loaded, but you should be able to stash it overhead! I guess whether or not it is a practical option would depend on what you intend to put in it!
Some of the features (like padded straps, trampoline suspension, etc.) definitely make it awesome for carrying a bunch of gear around while walking long distances regardless of whether you're in an airport or out in the woods.

Maybe should have gotten Deva 60

  • Familiarity: I've used it several times

I like the pack, the U-shaped duffel zipper access from the front is very handy and the included rain cover is a nice bonus. Not a whole lot of organization inside or out. Originally I had purchased the Deva 70, decided that was more capacity than I would ever need and went with the much lighter J63. I gave up the organization pockets, adjustable torso and plush shoulder straps for a reduction in weight of the pack itself. That said, I feel like I would have been more comfortable if I had gotten the Deva 60 instead, even with the lower capacity and slightly more weight.

She's definitely excited to us this pack

  • Familiarity: I gave it as a gift

I gave this pack to a friend as a birthday gift and she was nice enough to give some very good feedback.

"I have been searching for the perfect pack for years but could never commit to any - whether it was the price or the fit just wasn't quite right. But I just booked a two week trip to South America and decided it was finally time to choose a pack. I literally spent hours trying on different packs and loading them up with 25-50 pounds. This pack was the only one that truly comfortably fit.

I'm 5"4 and 120 lbs, so I went with the small pack. It fits every criteria other packs didn't: it doesn't dig into my shoulders or chest; the weight is distributed evenly and I don't feel any pressure points in my back or on my spine like other packs were causing. I haven't actually had the opportunity to use it yet, but from all my comparisons, it was the best fit. Not to mention the pockets and all the access zippers to the main compartment! It is a bit annoying that most of the buckles are the same size and it gets a bit confusing as to which goes where, but I feel like with a bit of practice and use, it'll be second nature. I'm definitely excited to put this pack to use. "
