  1. Great pack but,

    Loved this pack. My only complaint is no water bottle pockets. Mine was stolen from my car a few months back. Looking to replace it. on Jul 30th 2018

  2. Almost excellent!

    Keith designed a pretty awesome pack, but missed a few key points here! As an avid backpacker and United States Infantry Marine, i believe I have enough experience to speak on the issue and hopefully kelty will take a serious look at my few complaints.
    -The buckles and other headwear are not sturdy enough for serious abuse. Military rucks need to have durable hardwear. They get thrown around and beat on, and the flimsy hardwear on the pack currently is prone to cracking and being br Ken when being moved in and out of armored vehicles and aircraft. Lots of opportunities to snag and hang up there!
    -Dated waist belt hardwear! It is true that nearly every high end pack manufacturer has swapped to the much easier to tighten front pull waist buckle, including kelty on many of their civilian packs. Why not on this one kelty? That is a key feature that makes life a million times easier, especially when trying to work around other gear, like a plate carrier, weapon, and a thousand other pouches.
    -more rigid waist belt and much more substantial lumbar pad. These would make the ride of the pack so much nicer under a heavy load. A thicker lumbar pad also helps compensate for the fact that your rear SAPI plate is pushing the pack away from your back, and would make the pack a thousand times more comfortable with kit on!
    -a couple more compression straps. This is probably my most minor gripe about the pack. I use this pack as a main ruck, but also have flexed it into the role of and assault pack. Having an additional compression strap across the middle of the pack, and two that connect to the bottom of the suspension and connect about midway up the front of the bag would make securing a smaller, but still dense combat load much nicer!

    Kelty, these are all suggestions made from real world experience. For a pack over 300 dollars, these are essential things to add. Please take my suggestions and make these almost incredible pack see it’s real potential. I love the company and your products!

  3. First Impression:. 95% Happy!!!

    Just received my pack and it is everything the other reviewers say... Very rugged and well made!
    It has more usable/packable space than a very expensive high end 70 Liter elk hunting pack that I recently purchased and returned.
    One HUGE Plus (pun intended) is that the waist belt expands enough to fit fat guys!
    3 disappointments....
    1). No PALS webbing on the right side of the waist belt (very hard to see in the photos) for mounting a pistol holster and GPS pouch as I am right handed and plan on using the pack for back country deer hunting.
    2). Color(s): I wish O.D. Green was available as opposed to Coyote Tan and the same with the rain cover... Coyote Tan and White, these are the perfect combination of colors to get SHOT in the woods.during deer season!!! I will either have to wrap and orange vest around the pack or purchase a reversible camo/orange rain cover for use during deer season.
    3) The pack needs another set of rear vertical compression straps or a set of strap connection loops on the rear bottom and extra straps so that one can compression strap down a jacket under the main pack cover and then strap down rain gear between main pack cover and the removable top unit.
    Overall I am very happy with my purchase and am looking forward to using it soon.
    Kelty customer service went above and beyond to answer my questions... Thank you Danielle and to everyone I spoke with at Kelty for all of your help!!! 5 Star rating for their customer service!

  4. Wow

    Just received my pack from fed ex not only did I get it in a timely manner but the pack was everything I hoped it would be. Definitely well worth the money. It is well constructed with lots of room in it. My wife has already tried to steal it from me saying she wants one now. Thank you so much very pleased on Jul 29th 2017

  5. Customer Review

    I purchased this bag two years ago. I have used it on 2 deployments, where is worked well for a 72+ bag. It works well for that use. I have also used it on several multi-day hikes; this is where I wish it had a few additional features. One - pouches for hydration bottles that are more easily accessible than the main compartment. Two - zippered pouches on the waist for access to often used items. I ended up overcoming both of these by customizing it a little with the use of the multitude of MOLLE. Since this bag is listed under "Military/Tactical" I did give it 5 stars since it worked perfectly in that setting. It is a little heavier than your other 65 liter bags, but with that you get a material that will withstand much more that those other bags that may be couple pounds lighter; I have no fear of tearing this bag or breaking a zipper, it is up for the challenge. Also, I currently own several Kelty tents and other gear, and their service has astounded me over the years (replacing broken poles on a 15+ year old 4-season tent), they definitely keep my business due to circumstances like that. on Feb 15th 2016

  6. Customer Review

    I've owned this pack for more than 4 years now. It's very similar to the US Marine Corps ILBE main pack with a couple differences. The removable lid with strap was a great idea for keeping essentials and emergency gear in, in the case of an emergency. The padding and construction was very impressive and well done. Overall a great pack for those looking for a long lasting, durable pack. on Feb 6th 2016

  7. Customer Review

    I looked for months for the perfect 72 hour GO-Bag and had almost given up when I found this one. Hands down the finest pack I have ever seen. Kelty thought of everything. Highly adjustable...I love that I can take off the top bag and make the pack a better size for me but still have options. Included rain shield was a nice bonus and of course mo MOLLE is mo better. Thank you Kelty! I am so glad I didn't settle for the other bags on the market. on Feb 14th 2012
