The heavy pack sucks energy and detracts from the enjoyment of a long weekend backcountry. But withdrawing from the morning camp and putting on the Maven 55 on the trail is a whole new and wonderful experience. Thanks to its lightweight design, versatile features and highly breathable aerolon suspension. Maybe you are upgrading now.

Expert review

Adjustable size! !

Arisa Tanaka

ease of use

It becomes disappointingly stylish from the old design and personally disappointing ...



The size of the back can be adjusted, and it is very easy to carry because it can be fitted more to the body according to the back length of each person!

My shoulder hurts
If you have trouble, don't miss it !!

And it is lightweight.

ease of use

Other Zacs have been suffering from pain in their shoulders if they carry it for a long time.



Although it is lightweight, it has a firm hip belt and it is extremely comfortable without getting hurt on the shoulder.

From the product description of the manufacturer (GREGORY)

The customized 7001 aluminum alloy chassis and back panel design of the highly breathable mesh encapsulated matrix foam provide the lightest and most supportive Aerolon suspension in this weight class. The stability and operational comfort of Paragon and Maven surpass other lightweight packs thanks to Aerolon's exceptionally high breathability and dynamic load transfer system.

Aerolon's adjustable suspension, created from the responsive A3 suspension designed for Baltoro and Diva, uses an ultra-lightweight 7 mm hollow 7001 aluminum frame with an entirely new structure and flexibility. The chassis covers multiple torso sizes without compromising the perfect fit with the back. The curvature of the stay integrated into the system and the flexibility of the aluminum make it easy to adjust the torso to ensure the excellent fit and comfort expected of the Gregory suspension.

Lightweight yet firm waist belt support. It seems to be a strong companion for climbing for women!
