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.

Outstanding. Met my expectations in every way.


I appreciate the thought that went into building this pack the layout for me is simple, clean and efficient. I love how neatly it packs down without all the bs flopping around. Roughly 10lbs from being at hiking weight but it made the load feel lighter than my previous pack. I cannot wait to get out and run it.

Andrew Law
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.

Leslie Odegard
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!

Angelo Corrado
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.
