    We rated the K² 3500 Backpack best in class in our recent research: http://allamericanreviews.com/best-backpacks/ . This pack is designed with the hunter in mind – so many good features and solid compression system that’s easy to attach extra gear or game bags to the exterior of the pack. The full length pockets are awesome as well for carrying my rifle. Great pack.

    The pack works quite well. Just returned from putting this pack through its first real test and I’m digging it. I was able to carry an entire quarter from the moose I harvested in Canada. It was a ton of weight to be hauling but the pack handled it well. All that weight rode on my hips and didn’t feel hardly anything on my shoulders. I think my knees or hips would of gave out before the pack. I purchased the meat sling with my pack to help with these heavy loads. Only thing I would comment about the meat sling would be to increase the width so it wraps the wide loads better. While hauling these heavy loads I really like how easy the bag detaches from the frame so I could just focus on hauling meat. While hunting I also really appreciated all the different straps for tightening the bag up. It’s awesome how small and snug you can make this pack when maneuvering the this bush. No slopping or sliding around on the back or loose material to catch on brush. Also for the belt sizing, I typically wear a size 34. I’m 5’11” and 185 lbs. I ordered a medium belt but had to exchange it for a small after testing it with a little weight and I’m glad I did. Otherwise I would have never been able to crank the belt tight enough for the heavy loads I carried here. I did notice my small belt doesn’t tighten as nice as the medium belt I had at first. For some reason I have to suck in to get it to tighten at buckle otherwise it just slides on the connecting plastic loops in the middle of the belt.

    The reason for the four stars is because of the material used for the large center outer pocket in the middle of the bag is very elastic like and developed a very small hole already. I haven’t put anything in this pocket yet, but I feel if you put something hard in there and it stretches the fabric and catches on something it might tear a bigger hole. That pocket will come in handy for pack in hunts I’m sure, it’s just what do you stuff it with to not jeopardize the longevity of that pocket?

    Bought a 2015 3500 in time for late buck and used it as a day pack. Fortunately got to try out its load hauling capacity. The bag as a daypack is amazing. It has all the features I’ve liked about the various backpacks I’ve had and even a few that are new. The versatility of the bag and the lightweight make it awesome to carry all day long.
    The second to last day of the season I got to see how it did with half a deer in it. I packed it out three miles and I can honestly say my only complaint is the bag took zero weight off my legs. 🙂 It did an excellent job of putting the weight on my waist and the weight distribution is perfect with the meat shelf and load lifters. Only reason this isn’t a 5 star review is the belt has minimal padding and I have to make sure to keep my pants waistline in place or it creates hotspots on my hips. This was with a minimal climbing belt and suspenders.
    Definitely my favorite pack so far and would buy it again in a second.

    I bought this pack just before the start of rifle season here in Montana. Prior to purchasing this pack I used the Sitka Ascent for my day trips and kept a pack frame or game cart in the truck. Like a lot of other people, this meant extra trips out to get something to haul the first load of meat. After a ton of research and convincing my wife I needed another expensive piece of hunting gear, I pulled the trigger on the 3500 in multicam. Right away I noticed how lightweight and durable the pack felt. On long day trips I noticed myself not having to constantly adjust like I did with my old day pack. After the first weekend I returned home and ordered two accessory pockets and a hip belt pouch, both necessities in my opinion. Last weekend my hunting partner shot a mature cow and I was finally able to put this thing to the test. Loaded with everything in my day pack, a hind quarter, and backstraps/tenderloins/neck meat, we made our way four miles back to the truck. I was amazed at how well this pack carried a heavy load. There wasn’t a buckle or strap that moved, even when I slipped on wet sticks and almost went down. Everything about this pack felt solid. I will say that the hip belt eventually gave a couple hot spots, but I think its where the zipper on my jacket sits. I would recommend this pack to anyone from the weekend warrior to the experienced backcountry hunter.

    Bought the 3500 earlier this year when I was trying to decide on it or another high end pack. Ended up keeping the EXO for several reasons, first it’s comfortable. Second, I don’t much care for a pack that has no access other than through the top – the side zipper in the main bag makes it very convenient to get at what I want to without having to unload other gear. The fact that I can see what I want and remove only that item was a pleasure. Third is carried loads well and was very comfortable over the 100+ moles of himong/training/scouting/huntimg I did this summer and fall.

    I, unfortunately haven’t had the opportunity to pack out an amin all yet so the max load I have carried is 62 lbs but in doing so over 12 miles I can say it was unbelievably comfortable.

    I will say there are 2 issues I’d like to address. First, the hip belt could use additional padding on the sides, I found it tended to dig in a bit under heavier loads and second the webbing buckles on the waste belt are difficult to keep tight when carrying my pistol in a holster on the Web ingredients – the buckets slipped no matter what I tried leading to a loose holster.

    I loved the twisting ability of the frame. And although you never can really “forget” you’re carrying 40+ lbs, this pack did a nice job of not reminding me all day long.

    All in all a very nice pack.

    I recently used my 3500 on a 9 day elk trip in Colorado. I purchased a coyote brown pack with two hip belt pouches. I was tight on space but it held it all. The stretch pouches are amazing. I was very impressed with just how much this pack will hold.
    Pros, it very comfortable and moves with you. The side pockets are deep and they hold alot. The lower side pockets work well for items you want easy access to like a gps and calls. There is plenty of places to lash to.
    The cons, not much here realy. I don’t like the lack of organization of the pack. Maybe a small mesh organizer would help. It was a little noisy while I was hunting, but not game spooking loud, just annoying.
    Overall I love the pack and would recommend it to anyone.

    I have an original 3500 in foliage out of the first run and it’s a great pack. Took me alittle trial and error to get adjusted right but once I did it was awesome. It is easy to pack and get to my gear and I can easily haul meat in between the bag and frame and even toss some grouse in the front pocket. My should harness squeaks alittle but I’m never stalking with the pack on so its not a big deal. Would buy again and am actually thinking about grabbing a 5500 bag for alittle more room for family trips.
