Granite Gear thinks the Stratus suspension system is superior in every way to the traditional internal frame that uses a two dimensional plastic sheet and stay(s). When you try on a Cirrus, Stratus or Nimbus pack, this is what you will discover for yourself about our 3-D Composite Frame Sheet, Harness System and Pack Body:
3-D Composite Frame Sheet and Harness System
Even Load distribution
Stratus 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.
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.
Since our frame sheet technology (carbon fiber for Cirrus and T-PEX for Stratus and Nimbus) allows us to eliminate the need for aluminum stays, our 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
The exoskeleton belt design cups and evenly distributes the load over and around your hip bones.
This Pack Is 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
The 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.
Innovative Front Loading Backpack Design
STRATUS Access pack features a front panel that zips open on both sides from top to bottom and an internal compression system designed to keep your pack contents stable and in place while on a rugged trail. The real beauty of the Access pack design is that it allows you to easily access a piece of gear from anywhere in your pack without disrupting the rest of the pack contents. Once you try the Access system, you'll be hooked! The Access pack also features an external arch system that will allow you to lash just about anything to the front of the pack.
1. Exterior compression system helps to compact your load and offers a convenient and secure place to hold exterior gear like sleeping pads, Crazy Creek® chairs, etc.
2. Durastretch middle panel offers a hidden stretch pocket to stuff gear into pack from the top. Zippers are easy to use and work smoothly when opening the pack front.
3. Interior compression system holds pack contents in place and compacts your gear. This system offers the same packing efficiency of a top loader, and is far superior to a traditional panel loader pack.
