Selecting a Belt Size
Belt sizes align with average pant waist sizes. If you are on the break between sizes, we suggest ordering the larger of the two sizes. All belts will fit larger waist sizes, but not smaller than the advertised range. Below is the waist belt sizing chart for reference:
WAIST BELT SIZES
Small 28″ – 30″
Medium 31″- 36″
Large 37″ +>
Interchangeable bags and Frames
All past and current Stone Glacier bags and frames are interchangeable. This allows you to swap bags on and off your frame for different hunts you may have without requiring the purchase of a whole new bag and frame system. Many Stone Glacier customers own one frame with a smaller day bag, and a larger expedition-sized bag to have a system for day hunts and backpack hunts.
Materials
The overall goal was to build a durable load carrying pack, an ultralight pack without using ultralight materials. Stone Glacier packs are constructed of 500 denier Cordura fabric, X-Pac textiles and heavy duty webbing and buckles. X-Pac is a waterproof, USA manufactured fabric technology that has a tear strength double the military requirements for Cordura 500d and is used in the high stress, high wear areas. Cordura 500d is utilized for the main bag due to its balance of strength, flexibility, and noise reduction. The thread is a heavy duty, military grade UV resistant #92 thread. Buckles are Duraflex Berry Compliant heavy-duty military hardware. In every aspect, the most durable, technical, heavy duty materials were selected.
Load-Rating
We spent over 3 years of design and field testing with loads from 70 to 150 pounds without any structural issues to accomplish our goal. Here’s how we tried to break the frame…Starting with 1-inch steel plates 13” by 25”, we worked our way up to four plates in the pack. Each plate weighed about 85 pounds, 40 pounds per square foot. When it was time to add the third and fourth plate, we welded the plates together, lifted them with a crane, wrapped the Solo 3300 around the plates, and set it back down on the edge of the welding bench where we could get it on our back. The final load weight was 340 pounds with no damage, failure, or signs of stress. While the goal of testing to failure was not accomplished, the load test did prove the 150 pound plus load rating structurally conservative.
Frame Suspension
Hydrophobic foam, X-Pac fabric, Cordura 500d fabric and industrial hook and loop combine to provide a suspension with infinite adjustment and comfort. Using hook and loop for the shoulder harness attachment allows the user to not only dial in the exact height of the harness but change the angle each shoulder strap leaves the frame. This industrial hook and loop is rated at 17 pounds per square inch, 25% greater than standard velcro. Each shoulder strap has 24 square inches of contact, for a shear strength of 408 pounds per shoulder strap equaling over 800 pounds shear strength for both shoulder straps. The ultimate in adjustability and strength. The unique “X”, carbon and titanium composite, four stay design transfers load evenly to the hip belt while offering optimum load lifter angles. The load is supported by 12 connection points to the frame via 1″ webbing. The frame systems have revolutionized the standard of pack frame comfort and fitting ability.
Hydration
All Stone Glacier packs have two ¾” tri-slides to hang the Hydro Sleeve on the inside back panel. The Hydro Sleeve can hold up to a 3-liter water bladder. Once the Hydro Sleeve is installed, simply insert your water bladder into the Hydro sleeve and run the hose out the top. Hydration hoses can then be run through the hydration port found at the top of all Stone Glacier bags and routed down either the left or right shoulder strap.
Which Stone Glacier frame is right for you?
We make two ultralight, load-hauling hunting frames: the Krux and the Xcurve. Both frames are compatible with every SG bag (except R3 bags), and each feature adjustable lumbar support and an integrated Load Shelf rated for 150+ pounds.
Although the frames are similar in design, they have one key difference: the Krux Frame features straight carbon stays and the Xcurve Frame features curved carbon stays. This difference accounts for distinctly different back shapes and allows the wearer to achieve a comfortable fit depending on the size of their torso and shape of their back.
Through a decade of fitting individuals into packs, it is our experience that the majority of people prefer the fit of the Krux Frame.
STONE GLACIER FRAMES
Krux Frame
- Our most universally fitting frame
- Generally fits people with a flatter back and torsos under 19”
- Generally fits women better than the Xcurve frame
Xcurve Frame
- Generally fits people with a more pronounced curve to their back, particularly in the lumbar
