Love this pack ever since I got it. Holds the load really well against your body and is very comfortable. Can’t wait to get some more miles with it this spring and fall.

This pack far exceeded my expectations in both comfort and performance. I could cary a 60lb load and i never felt the weight on my shoulders!!

Before using the IA4k, I had a mystery ranch metcalf. Everytime I packed an animal out with it, I would get the worst pain in between my shoulder blades. Not with the IA4k! This year I was able to pack out a bear, elk and deer all with this pack and by the time I made it back to the truck, I wasn’t cringing in pain. Do not hesitate to buy! Plus made in America!!!

I have used most of the top brand packs on the market and This pack is by far my favorite. I’ll as someone who has suffered a burst fracture of the L1 vertebrae, having a good pack is critical to me being able to hunt. I have run this pack for three seasons now and have logged well over 100 miles in it without issues. The little details make a big difference. Simple things like the little lips on the frame that a sling hooks on is something that makes these packs top notch. I have and will continue to recommend these packs to fellow hunters. Last but not least is one of the most important things in my opinion and that is customer service. Initial Ascent customer service is second to none. Every dealing I have had with them has been amazing.

So far my IA pack system has been an invaluable training tool and one of my favorite pieces of gear when I am actually able to get out hunting. I’ve carried up to about 100lbs more comfortable that I would have thought possible. My training weights consist of steel plates, various sand bags and my 4 year old son. So I’ve carried different shapes, sizes and even wiggly loads with not a single hot spot or issue. I’ve hunted with the pack in 4K/Lid and Pannier/Lid configurations and aside from some of my gear being less than size efficient and my “need” to over pack for almost all occasions they are both awesome setups. A person with more minimalist taste or more ultralight gear could probably get a weekend hunt out of the Pannier/Lid without a problem.

I’ve used this pack for two years now, doing everything from back country bulls to flyfishing 5 miles back in the wilderness for a few nights. It holds what I need and can pack out a lot of meat. 4 bulls in two years and my son and I packed em out one trip each. Easy to reach side compartments,and the frame itself is a dream. Once you get it buckled and tight the load doesn’t move. I Love this pack !

This is the most thought out and complete system on the market! With the ability to go big at 6500ci and in less than 2 minutes I’m in day mode at 850ci, then I can be at an additional 2500ci in my load carrier faster than you can say “great shot”!! With a 1.5 liter Platypus bladder that fits perfectly in the lid there is never any squishing my bladder while carrying a load! F#%=ing Brilliant…..just saying!

Love this pack. Super comfy. Haven’t quit put it through all the paces yet, but so far so good. More important to me is there customer service. Anytime I have had a question or concern about anything from any of there gear to shipping they have responded. And quickly too. I have never had to wait with. Keep up the great work

Thanks for the feedback Jason. We are constantly working on different options for our packs. We are looking at several camo options and trying to decide if that is a road we should go down. Thanks!

These packs are where it’s at I’ve had my IAK4 for a few months and have put many miles on it. I love how diverse the pack is, and how I was able to adjusted it to fit my long torso.
The dudes at IA provide great customer service and really go the extra mile for you literally you cannot go wrong with Initial Ascent.

I love this pack. Plenty of space for your backcountry bivy hunt, easily broken down for your daily hunts and it’s attached to this best pack frame I’ve ever used. This unit was a vital part of packing in a camp and packing out 2 big bulls and 2 mule deer bucks. Dennis and Joe have placed countless hours in the trial of these packs and it paid off for me this year. The details of the bag are listed above and I’d challenge anybody to find a better bag on the market (to include customer service). Not only is this my go to hunting bag but if I were to deploy again it would go with me. This is a first class hunting pak system, backed by first class customer service.

I’ve used the IA4K for over a year now, and this pack system has satisfied nearly all of the needs I want in a pack. The versatility and comfort are unmatched. The features are very well thought out, and really provide a user friendly pack solution. Likely my favorite feature is integrated gun strap notch in the frame. It doesn’t sound like much, but it eliminates the distraction caused by wrestling with your gun sling while hiking. I also really like the water storage in the lid, the external tripod and spotter pockets, and the adjustment versatility. All in all, this is the one of the best designed packs on the market. And, at a little over 5 pounds for the whole kit, you are not sacrificing weight for functionality.

This pack is amazing. I’ve tried several packs on the market, with each one having its ups and downs, but this pack changed everything for me. It is comfortable, light weight, and extremely versatile. These packs have changed the way I hunt and hike forever. If you haven’t tried one of these packs you don’t know what your missing.

Got this pack for its claim of hauling heavy loads really well. It is also supposed to keep the weight on your hips without sliding down on your butt. It does everything promised really well no slipping and carry’s weight great and customer support can’t be beat.
