Even Load Distribution
Cirrus, Stratus and Nimbus frame sheets are molded to follow the vertical and horizontal curves of your back, eliminating pressure on your lower back muscles.

Better Blood Flow and Oxygenation Through Your Back Muscles
The fit of the frame to the curves of your back puts less pressure on individual areas of your back allowing for increased blood flow and oxygenation to your back muscles.

Great Head-Room
The head-room pocket is molded into the frame sheet so you always have maximum head-room, no matter how the pack is loaded

Perfect Fit for Men or Women
Four men's and four women's sizes of ergonomically sculpted belts and plus various sizes of frame sheets and shoulders straps, are available so you can expect a perfect fit whether you are short or tall, heavy or slender.

Light Weight
Since Granite Gear's frame sheet technology (carbon fiber for Cirrus and T-PEX for Stratus and Nimbus) allows them to eliminate the need for aluminum stays, their backpacks are the lightest internal frame systems available to carry heavy loads.

A Very Well Cushioned and Stable Ride
Dual density foam lamination in the shoulder straps and belts effectively cushions the load and absorbs shock.

No Hot Spots
A wrinkle free and smooth surface on the inside of the belts and shoulder straps eliminated hot spots.

Reduced Hipbone Fatigue
Granite Gear's exoskeleton belt design cups and evenly distributes the load over and around your hip bones.

Granite Gear Packs Are In Tune With Your Natural Body Motion and Shape
The belt naturally rotates to follow and move with your hip motion. The shoulder straps automatically cant to match your shoulder angle for even load distribution.

Amazing Load Control and Stability
Granite Gear's Cruise Control hip stabilizing system allows the pack to effectively move with your natural body motion. This keeps the pack over your center of gravity and amazingly stable, for a degree of freedom of movement that must be experienced to be believed.
