What is the most common question we receive here at Initial Ascent??
What separates Initial Ascent Packs from ALL the other packs out there?
Simple. Our frame and suspension is second to none and is built to pack extremely heavy weights more comfortably than the competition.
The Integrous Frame is the foundation of our system. You might be thinking "Integrous"? What does that mean?
INTEGROUS is a word not often used but simply means
"with integrity".
Integrous Frame
It took over 3 years of research, development, and testing to finalize a solution. Our frame has gone through 16 (some subtle and some not so subtle) versions to get where it is today. Three groups of engineers helped out with the recipe, shape, and construction. This frame is what sets us apart from the other high-quality hunting backpacks in the industry and is result of unrelenting passion and detail.
The triaxial weave carbon fiber composite structure provides the greatest strength to weight ratio on the market. We've tested every possible combination of materials, and we are confident in delivering a frame that is not only comfortable, but provides the ability to haul extremely heavy loads. The key to the frame's design is its shape. The frame is wider than most all systems which increases the surface area of the load against it, therefore keeping more weight close to the body. This allows the heaviest load to be positioned in the center of your back by spreading the weight over your hips, minimizing muscle fatigue and shoulder strain. The frame also follows the natural curvature of your spine which helps keep loads closer to the body. It's all about trying to get the center of gravity of the backpack as close your body's center of gravity. Furthermore, our bags are designed more like a rectangular wedge vs. most bags are shaped like a tube. It's just physics. Torque (amt of work necessary)=Force x Moment Arm 
Our pack is the only pack on the market able to carry quarters on the side by using the upper limbs of the frame and the notches for your rifle sling. This method was invented by Dave Beronio of R&K Hunting Co. Dave packs animals off the mountain for a living for clients and must make his efforts as efficient as possible, sometimes carrying all four quarters and loose meat in ONE TRIP. Carrying two quarters on the side puts the weight as close to your center of gravity as possible.
Hip Belt
Three-piece system designed with 1" closed cell foam as well as an additional layer of "Smart foam" in the lumbar region. Not only it is 2-stage, the lumbar system is designed to allow for adjustability by easy access to the foam insert providing complete customization dependent upon the user. This is THE MOST COMFORTABLE lumbar system on the market today.
We use "Slip-not" material on the lumbar region to make sure the pack system does not slide on your back even in the hottest environments with heavy loads. 3-D spacer mesh is also utilized in our hipbelts for added comfort and breathability.
