FAQS
-
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.

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.

The material we use is a 500D Cordura which is very water resistant but not waterproof. If your hunting in wet environment, we recommend out IA Rain Cover.

There's nothing better than the Intial Ascent Packs. As you can see we have the addiction. Thank you for making our hunts easier and our loads carry so nice! Eric Emery
Best packs I've ever used.
I've kept an eye on initial ascent bags for a couple years now and with the bag changes for 2024 I decided to pick one up. I was sold on a pack after actually trying one on at the 2024 Hunt Expo and feeling how comfortable 55lbs and 155lbs were loaded on my back.
Awesome pack… so easy to use and just handy all round
I might have been better off getting the 8K, but I will just get creative on the load out, and maybe not be so high maintenance on my backcountry hunt, lol. But the bag is amazing. The weight is so easily managed, it feels much less than it is, and I am able to compare this with my ( now ) training Mystery Ranch Beartooth 80. Lots of adjustability, which I am still playing with. I had also purchased the 3K, and have moved the bags around on the frame, which is easily achievable. And everything is so.....quiet. Lastly, great tutorial support on YouTube and site!!
I replaced my 4K bag with the new 5K bag on my Initial Ascent pack system recently. I love the new design with its Horseshoe front zipper, expandable front pocket, roll top and rifle side pouch. I am 60 years old and the Initial Ascent Pack System has improved my hunting capabilities greatly, I highly recommend!
Simple and straight forward. Just what I need and nothing more. I'm a fan.
Should be a great addition to my system. Can't wait to use it this season.
Quality products that perform in the field! Love it!
