F.A.Q.

What other hunters are saying

“By far the best pack I’ve owned. And… I’ve owned a few.”
Troy Huggard

“The term coming out heavy was very real. Hind quarter and the full head. 4 miles, all uphill. I loved my Initial Ascent pack from prior experiences, but am amazed at how it handled the weight. I was definitely over 100lbs on this trip and had zero hot spots the next day. I was stunned, other than usual soreness from the miles and weight, I surprisingly felt great the next day. Buy gear you believe in.”
Chris Young

“The pack worked flawlessly and allowed me to carry out a moose in six trips.”
Jason DeWeese

“Love the pack. It’s awesome to be able to go out with a load.”
Trampas Meidinger

“The pack was a life saver! I weighed it when I got home and it was 100 pounds and due to all the features you guys put into the design allowed me to pack both elk out with no hot spots and rubs anywhere. The only part that hurt were the legs. Thanks again Sir!”
Elijah Hultman

“Day mode also works as a great upland game pack. I love my IAK 4 system, so many uses.”
Zach Diaz

Frequently Asked Questions

What makes the Initial Ascent carbon fiber frame better?

 After three years in development and 15 generations of design, the Integrous Frame and suspension is the result of unrelenting passion, detail, excellence, and success. This quality design is the pinnacle in ultralight backpacking frames and suspensions. The triaxial carbon fiber structure combined with additional strategically placed composite materials provides the greatest strength to weight ratio on the market.  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. 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. To stay cooler in hot conditions, the shape maintains air flow around your back. The frame also follows the natural curvature of your spine, providing extreme comfort in all conditions.

How many different bags are available?

One at the moment which is the IA4K (4000ci)

What materials make up the IA Bag?

The soft goods are made up of primarily 500D Cordura. We use YKK waterproof zippers. Duraflex hardware is used for all buckles. Expandable mesh is used for the expandable pockets.

What is your warranty policy?

Initial Ascent is confident that our products will meet and exceed your expectations. We test our products to failure so you don’t have to. We offer a 100% lifetime warranty for any material defects and workmanship to the original purchaser. For any damages outside of normal wear, we can repair it at a reasonable cost. The Integorus Frame has a LIFETIME GUARANTEE.

Do you have a camo pattern available?

We are currently working on releasing a camo model in 2019.

What size bladder fits in the water bladder pocket in the IA Lid?

You can store up to a 2.0L low profile water bladder in the lid.  We offer the Platypus 1.5L Big Zip low-profile with the 4Gear Combo Kit. It can also be added to any existing IA pack.

Where is your product made?

Our products are made in Idaho, USA.

Are the bags modular/interchangeable?

Yes. All IA packs work off of a single frame and suspension system. You can interchange the bags and Pannier Load Carrier at will. No need to buy a separate suspension system.

What is “Day Pack Mode”?

Combining the Pannier load carrier with the lid makes for a perfect Day Pack system. This design allows for speed and agility while providing the storage to carry the essential items for a day hunt.

Are your packs waterproof?

The material we use is a 500D Cordura which is water resistant not waterproof.
