Real World Reviews

Colton Heward

After 60 days of using and abusing the K4 Prototype last fall, I can confidently say that it is the most comfortable, complete, and capable hunting pack that I have ever owned. It was clearly created for serious hunters, by serious hunters.

Paul Servey

The new K4 is the best pack I have used to date. I used a K4 Prototype on 5 big game hunts this past fall and could tell that it was strategically built for comfort and is tough enough to withstand the most extreme hunting and backpacking adventures.

Steve Evans

I love the simplicity of the K4! It has everything you need, and nothing you don’t! After testing the K4 Prototype last year, I was thrilled with the new system to detach the bag from the frame. And the new hipbelt design provides a noticeable increase in comfort.

Best Camera Pack

I use this pack for hiking in heavier camera equipment. This is the only pack I have found that is actually comfortable. Hands down best pack I have ever owned.

Just what I was looking for!

Received the K4 5000 pack in the mail. Setup instructions were clear and simple. Had my pack adjusted in minutes. Was able to use the pack for the fall 2023 hunting season. Love the balance of weight but still making adjustments on loading supplies. The waist belt was perfect for me as I deal with back issues after rupturing my L3 disc 410 years ago. The belt gives me great support and the overall comfort of the shoulder straps and adjustments work great. Once strapped in the pack never moved out of position. I am 64 years old and now have a pack I can use for the rest of my lifetime. Thanks Exo Mtn!

K4 5000 Pack System

An excellent design and very well thought out. I'll be 59 this year and for us older types this is a game changer. For anyone in my age bracket that has been active and has enjoyed the outdoors all their life, this will help you stay in the game a few years longer. Less fatigue, better fit, and an incredible hip belt that essentially eliminates slipping. Far superior to anything I have ever used before and it will allow me to go further and in much greater comfort. For the older hunter, hiker, adventurer, a must have piece of equipment.

A more-than worthwhile investment

This pack was a large investment for me (and I’m sure many others who have chosen to purchase it). EXO’s service and commitment to their customers and their values are second-to-none. This pack has proved its value to me each time I’ve used it.

It might be slightly unconventional for a regular guy like myself to own this pack; I go on 4 or 5 overnight hunting trips a year (only one of which being long/remote enough to warrant a 5000ci pack), but I have 2 kids and spend a lot of time in the woods with them canoeing, hiking, snowshoeing, etc. This pack has been an absolute life saver for anyone who is tasked with carrying nearly everyone else’s gear for a family camping trip or hike.

A couple things I love most:
The locking buckles EXO sent with the pack. They’ve made it so easy to fasten multiple sets of snowshoes, trekking poles, etc onto the pack quickly without worrying about them coming loose or falling off.
The dry bag insert.
The dry bag insert completely transformed how we canoe-camp. I can worry less about access/portages now knowing that I can carry absolutely everything in one pack AND the canoe, and my toddler can get himself to the next put-in.

I use this pack as a day pack most often, and I had concerns that it would be too large. I talked with Mark a few times as I was very close to ordering the 3600 but was concerned it wouldn’t be large enough for me due to my lack of packable gear. Mark steered me toward the 5000 and I’m glad he did. The horseshoe zipper is my favorite feature, and the bag collapses down to nothing when it’s lightly loaded.

I initially wasn’t able to use the stuff pockets at the bottom, but I rerouted the compression straps through the relief hole that EXO integrated which makes it possible to use those pockets even with the bag fully compressed. Great design on their part.

This bag will likely last the rest of my life, and I can’t imagine why I wouldn’t someday be passing this pack down to my son/daughter. It was a great investment and I’m very glad I chose the EXO.


Great fit and extremely adjustable!
