The versatile Paragon 38 pack employs an innovative suspension system that allows it to comfortably carry up to 40 pounds and stow 2319 cubic inches of gear at a weight well below that of its load-hauling peers. Adding value and functionality, Backcountry Edge includes a 3D Hydro Reservoir.

Equipped with Gregory’s Aerolon suspension system, the pack employs an ultra-lightweight hollow 7001 aluminum frame and a mesh-encased, die-cut foam backpanel to offer excellent load stabilization and ventilated performance. Adjustability in the harness allows you to customize fit. Load lifter straps and an adjustable sternum strap further enhance fit and ensure stability. Siliconized padding in the lumbar portion of the pack increases comfort and aids in load transfer. To ensure a customized fit, the pack is available in Small/Medium (fits torso sizes ranging from 15”-19”) and Medium/Large (18”-22”) size options.

The top-loading main compartment of the pack has an extendible drawstring closure. A zippered front entry allows access to a separate, lower sleeping bag compartment. A large front stuff pocket provides a place to keep discarded layers or other gear easily accessible. Zippered lid pockets and zippered hipbelt pockets offer additional organizational options. Side compression straps allow you to cinch down the packbag to keep the contents of the pack stabilized and they double as external lash points.

Other features include large side stretch water bottle pockets, trekking pole attachments, a front harness quick-stow feature for sunglasses, and an included raincover. An integrated sleeve and exit port make the pack hydration compatible (3D Hydro Reservoir included).

The Gregory Paragon 38 backpack is available in your choice of size and color options.

Very Comfortable
Reviewed by M L - February 4, 2019

Likes: There is no denying the comfort of gregory packs and the Paragon 38 is no exception. I have had this pack fully loaded with winter gear and it's extremely comfortable and roomy. The stretch pockets really stretch allowing for lots of room for larger water bottles on sides and bulkier layers in the front pocket. The included hydration bladder adds even more value to this pack!

Dislikes: I would have liked a divider inside at the bottom. The side compression straps are rather thin so I wonder about long term durability. Other than that, I really like this pack and cannot stress enough how comfortably it carries the heavier load.

Good backpack
Reviewed by Hsing-o L. - July 23, 2018

Likes: The included 3D HYDRO RESERVOIR adds functionality and value.
The ventilation of the backpack is also very good.

Dislikes: no

Awesome bag and hydro reservoir
Reviewed by Brett M. - February 13, 2018

Likes: I really liked how you were able to have a good sized hydro reservoir and still be able to carry a good sized load in the rest of the pack. The two side pockets had plenty of flexibility an security for many different sized water bottles an other items. The small zipper pockets on the support straps are also very convenient for small items that get used often without having to dig through the bag.

Dislikes: None as of yet
