Backcountry Tested: AKEK Climax 5400 Pack Review for Elk Hunting and Backcountry Trips
When it comes to elk hunting or multi-day backcountry expeditions, the right frame pack can make or break your experience. Recently, I’ve had the opportunity to put the AKEK Climax 5400 to the test, and after a couple of months of use, it’s time to break down my thoughts for anyone considering this pack for their next big hunt or remote adventure.
Overview and First Impressions
The Climax 5400 is a large-capacity external frame pack, built with serious backcountry hauling in mind. Right out of the box, its lightweight feel and exposed carbon fiber frame stood out. The pack does feel light but I need to mention the pack isn’t the lightest in comparison to other similar sized bags on the market coming in at 6 lb and 12 ounces. The external frame is visible and integrated directly into the design, which might raise eyebrows for some, but the padding around the lumbar and shoulder areas compensates well.
The build quality seems durable, and there’s no shortage of compartments, straps, and storage options (see how these play into the pro’s and con’s discussion later on). The entire bottom six inches of the bag is waterproof, something you’ll appreciate when dropping your pack in snow, mud, or a wet riverbank. It also includes a rain-fly (integrated but removable), which adds even more weather protection.
Comfort and Fit
The lumbar pad is one of the first features I noticed performing well. It’s thick, doesn’t dig into your lower back, and has a rubberized pattern that encourages friction and prevents the pack from sliding down while on the move. Waist and shoulder straps are adequately padded, though I feel the shoulder padding could be beefed up slightly. They’re not uncomfortable, but they lack the rigidity and possible long-term support I’ve found in comparable packs like those from Exo Mountain Gear.
The shoulder strap height adjustment is simple and intuitive with a Velcro-and-tab system that lets you dial in the fit across four or five different slots. For extended hikes or heavier loads, a well-fitted pack like this is crucial.
Storage & Organization
If you're someone who likes to keep gear organized, the Climax 5400 absolutely excels. There are multiple internal mesh compartments, removable accessory bags, and hip belt pouches that come included, something that most brands sell as add-ons. One especially handy feature is the removable ammo sleeves in the hip pouches. Whether you're carrying rifle rounds, a rangefinder, or batteries, they help you stay ready without digging through your bag.
The main compartment is large and well designed with room for food, clothes, sleep systems, and more. It also includes a dedicated space for a hydration bladder, and there’s plenty of space to stash optics or a spotting scope in the side-access pockets.
The top lid is removable and cleverly doubles as a minimalist day pack. For elk hunters hiking miles away from camp, this is a huge plus. You can leave the bulk of your gear at the tent and still carry essentials like knifes, tags, GPS, a couple of game bags in a much lighter configuration.
Meat Hauling Capability
The meat shelf system is well thought out. I strapped a roughly 40 lb concrete block into the shelf and went on several test hikes. The load stayed tight to the frame and didn’t bounce around which is a noticeable advantage over internal frame packs like the Sitka Mountain Hauler. Once the main pack is detached, the exposed carbon frame handles awkward or heavy loads comfortably and securely.
It takes some time to get used to all the straps, and there’s a learning curve when separating or reattaching the bag to the frame. But once dialed in, the system works efficiently.
Unique Features
One of the more polarizing aspects of the Climax 5400 is the strap system. Instead of standard buckles, AKEK uses a unique fastener. They’re quieter (great for stealth), but take some getting used to. Personally, I’d prefer traditional buckles for their simplicity, especially when dealing with gloves or cold fingers.
Another standout feature is the built-in weapon carrier, which can accommodate a rifle or bow. It's adjustable, and although I didn’t demo that part extensively, it's clear AKC put some thought into the design.
Pros
Price Point: At $597 (with free shipping), this pack includes everything (lid, rain cover, 2 hip pouches, 2 accessory pouches with no hidden add-ons.
Organization: Best-in-class pocket design and accessory storage.
Load Stability: External frame and compression system keep heavy loads steady.
Weather Protection: Waterproof base and integrated rainfly offer solid protection in wet conditions.
Convertible Lid/Day Pack: Saves weight and adds versatility.
Cons
Learning Curve: Strap system is not intuitive at first; beginners may struggle to get it dialed quickly.
Shoulder Strap Padding: Could be more robust for long-term wear and durability.
Made Overseas: Not fully manufactured in the USA (common in the market, but worth noting if that's important to you).
Fastener System: Quiet but less intuitive than standard buckles.
Final Thoughts
The AKEKClimax 5400 is a legitimate contender in the backcountry hunting pack market. With features that rival big names like Mystery Ranch, Exo Mountain Gear, and Sitka at a significantly lower price. This pack is more than just a budget option; it’s a smart, capable tool for serious hunters.
Whether you’re heading out for a 5-7 day elk hunt or planning extended backcountry trips, this pack has the capacity, organization, and frame support to get the job done. It might take a little getting used to, but once you’ve got it dialed in, it’s hard to beat the value.
Next Step: I’ll be taking this pack on our next elk hunting trip later this September and will follow up, hopefully with some meat in the load shelf.
