We are proud to say that all of our packs are built exclusively and entirely in the USA. We wouldn't have it any other way.

We also source all of our raw materials and components from the USA whenever possible. For more information about the materials we use to build our packs, please visit our Material Details page.

Exo Mtn Gear is proud to offer a Limited Lifetime Warranty on all of our packs. We also offer a 30 Day Trial Period with every pack purchase.

The warranty covers defects in materials and workmanship for the lifetime of the product, for the original owner. The warranty does not cover loss/theft, negligence, abuse, misuse, or normal wear that occurs over the life of a product.


If you have any questions about warranty coverage or repair services, please contact and include relevant photos of the issue in question.

We sell our products online, directly to our customers. This direct sales model allows us the opportunity to use the best materials and the best construction methods possible, and to do it all here in the USA. (You can learn more about our pricing and sales model in the question below.)

We know that purchasing a pack is a big decision, and we want to do everything we can do — both before and after a sale — to make sure you get the pack you need and the performance you are looking for. We offer a 30-Day Trial Period with every pack purchase, so that you can receive the pack, get it fitted to you, load it with some gear and/or weight, and make sure it meets your expectations. If you decide for any reason to return your pack within that 30 days, we will be glad to accept your return and issue a full refund when you ship the pack back to us in “like new” resellable condition.

If you have questions about which pack to choose, please look over the information below or give us a call to discuss your needs: 208-995-4688


Our K4 Frame is offered with five different hipbelt sizes (XS, SM, MD, LG, XL), and four different frame heights (22”, 23.5”, 25”, 26.5”). The frame’s suspension also features 6” of micro-adjustment to fine-tune the fit to your unique body shape and size.

Put simply, we have an option to fit nearly any body size and shape.


In addition to the size selection information that is needed before you purchase a pack, we have detailed information on how to adjust your pack for optimal comfort and performance when you receive it. And as always, our small team is happy to personally assist you with any sizing or fitting questions you may have.

First and foremost, it is important to know that each of our bag sizes — the 3600, 5000, & 7200 — share the same K4 Frame, and each bag can swap on/off the frame with ease. Bag selection does not determine fit or meat-hauling ability; it determines the volume of storage you have for your gear in the selected bag. All of our packs use the same K4 Frame and have the same capabilities for fit and load-hauling.


K4 3600 — Efficiently designed for those that like to move fast and light, the K4 3600 is an ideal pack system for ultralight adventures up to 3-5 days.

K4 5000 — A perfect do-it-all hunting pack. The K4 5000 offers the space you need to pack for a 5-7 day backcountry trip, yet can still compress down to a streamlined profile when only carrying the essentials.

K4 7200 — The space you need for expedition-style adventures without the burden of added weight or complexity, the K4 7200 weighs less than 6lbs and can carry 10+ days of gear with ease.

We design our pack systems to be functional and capable, without the need for numerous add-ons. In our opinion, a pack that is purpose-built for hunting shouldn’t require the purchase of accessories to effectively carry meat or a bow, for example. Additionally, we always strive to keep our packs lightweight, streamlined and efficient — not cluttered with excessive pockets or covered in complicated attachment points for every imaginable scenario.

The accessories we offer are purpose-built to enhance the functionality of the pack but are not required for every person or situation. The most common accessories for our packs are the Hipbelt Pouch, the Quick-Release Rifle Carrier, and the Nalgene Holder.



The cost of our products is a direct result of the quality of the materials we use, and the fact that we build our pack entirely in the USA.

We use the highest quality USA-sourced Cordura fabrics, custom Carbon Fiber frame material, specialized stretch fabrics, premium-grade YKK zippers, and the highest quality of buckles and hardware. All of these high-end materials are then put in the hands of highly skilled workers and turned into an Exo Mtn Gear pack, and it is all done right here in Boise, Idaho, USA.

We are only able to produce a pack of this quality at this price because we sell directly to you. In general, the products you see on store shelves and at retailers have a large amount of markup built-in to the price you pay. Because we operate on a direct-to-consumer sales model, we do not have to increase our prices to pay for distribution and create extra profit margin for retailers or dealers. Each step between the producer and the consumer costs money, because each person involved has to make money. Eliminating the middleman allows us to sell directly to you and keep our costs in line.

To help keep our costs low, we also avoid traditional advertising and marketing expenses. We operate with a very lean staff and very little overhead.

Put simply, we invest in delivering the best product and the best service possible, while seeking to eliminate any overhead costs that would otherwise increase the price of our products.

Historically, we have just one sale a year, around Black Friday. The format of that sale changes year-to-year.

We offer everyday discounts for US Military (active and veteran), Law Enforcement, and other professional "in the field" professional responders, such as Firefighters and EMTs. If you qualify, please create an account and then email any proof of service or employment to to get setup with the discount.

We also have a Guide Discount program for professional big game hunting guides.

When placing an order, you will see multiple shipping options and costs after you enter your billing and shipping address on the checkout page. The rates are determined by the items being purchased and the delivery address on the order. We use both USPS and FedEx for our shipping carriers.

Shipping to Canada — We ship our packs to Canada via USPS or FedEx International. All of our packs are made in the US and are documented accordingly, so while local taxes (GST and/or PST) may be assessed at the time of import, there should not be any duties incurred.

International Shipping — We ship internationally to many countries. You can get an exact shipping quote for international destinations by adding items to your cart and then entering your specific delivery address on the checkout screen. Unfortunately we do not have any oversight of any import duties or customs charges that may be assessed before delivery.


The fitting process is incredibly easy. Just follow these step-by-step instructions.

The short answer that we like to give to this question is, “More than you can.”

Our frame was specifically designed, engineered, and built to haul heavy loads of meat out of the backcountry. Everything — from the Carbon Fiber frame structure, to the fabric, webbing, and buckles on the frame — is built and tested to withstand heavy loads.

It is also important to know that all of our pack systems can handle the same amount of weight, because each of our packs utilizes this same K4 Frame. No matter if you’re carrying the day’s essentials in a K4 3600, or 10+ days worth of gear in the K4 7200, you can quickly and easily begin loading meat on the load shelf between the bag and frame and have the ability to haul heavy loads at a moment’s notice.

Our K4 hipbelt features laser-cut MOLLE panels on the hipbelt, which can accept a wide variety of MOLLE-compatible pistol holsters.

While many holsters can work, there is only one holster design that is designed and built specifically with our packs in mind — The Ivory Holsters EMG. We have no financial connection or incentive to Ivory Holsters, but we did work with Ivory to create the EMG as a holster that is specifically designed and optimized for use with our packs.

Our pack systems work great for whitetail hunting. The load-shelf between the frame and bag works great for hauling treestands, saddle hunting platforms, climbing sticks, and even ground blinds. Our larger bags also compress down really well when you don’t need the bag’s full capacity and want a low-profile setup in the tree. In these articles you can see examples of How to Attach a Treestand to an Exo Mtn Gear Pack System and Pack Systems and Saddle Setup for Whitetail Hang-and-Hunts.

Unfortunately, “waterproof” is a term that is used too often. If something is truly waterproof, it is impermeable. The term that most products should use is “water-resistant”, which is what our packs are. The fabrics we use do a great job of shedding water, but they do have a saturation point. We do not worry about the contents of our packs when used during passing showers, some exposure to snow, etc.

If, however, you are using our packs in very wet conditions and climates with prolonged exposure to moisture, then some additional protection for sensitive items might be necessary.

The common approach to adding a water barrier to a pack is to use a rain cover. However, rain covers have numerous drawbacks — they are typically loud, they easily get hung-up or torn off when hunting in thick terrain, they completely limit the functionality of your pack by completely covering all pockets and access points, and many times they simply redirect water to certain areas that get wet anyway.

Instead of putting protection over our bags, we decided to put protection in our bags with our K4 Dry Bag Liners. These dry bags are size-specific for our three pack models, and integrate directly with the roll-top enclosure on those packs.

By putting K4 Dry Bag inside the pack, the external pockets and access points of the pack are still completely accessible and fully functional. You can divide your gear inside the main bag, so that some of it is stored within the K4Dry Bag, while other less-sensitive items are still stored within the main pack bag and fully accessible via the zip-access to the main bag. With this approach you can fully protect things like your sleeping bag and clothing, while still keeping other items, such as your food, readily accessible.

The K4 Dry Bag can easily be removed from the pack, which is a great option if you are packing into a “backcountry basecamp” and want to leave some gear at camp, while carrying other essential gear with you each day. The K4 Dry Bag can also be run in the load shelf between the pack and frame, extending the gear-hauling capacity of any of our pack systems.

Best of all, the K4 Dry Bags are truly waterproof, offering ultimate protection when it matters most.

We recommend cleaning your pack after each time you pack out an animal, or at the very least after each hunting season. It is also wise to clean your pack before hunting starts — especially if you have been using your pack for pre-season training or scouting trips leading up to opening day.

Thankfully, the cleaning process is quick and easy…

  • Completely empty the pack of all gear, wrappers, debris, etc. Be sure to check all pockets and compartments.
  • Separate the bag from the frame to expose the load-shelf area between the bag and frame. (You can optionally remove the bag from the frame, or disassemble the frame components, but it is not required.)
  • Rinse the pack and frame. Do not use a high-pressure washer or nozzle.
  • Fill a tub, basin, or large bin with cold water. The colder the better.
  • Soak the pack and frame in the cold water. Flush and refill the water as needed.
  • Hand-wash any trouble spots with a soft rag and a mild detergent.
  • Give the pack and frame a final rinse.
  • Hang all pack components out to air-dry.

Each airline defines their own policy for carry-on luggage, including size restrictions. Our packs do not technically fit within the size guidelines for most airlines. However, we have flown countless times — both domestically and internationally — with our packs and have not had issues using our packs as carry-on luggage.


We do recommend keeping the pack looking as streamlined as possible by packing efficiently, keeping loose material managed, and excess webbing secured. You may consider removing the pack lid to further reduce the height of the pack.

Be sure to check both airline and TSA regulations to ensure that the contents of your pack meet all security guidelines and do not contain restricted items, such as hunting knives, ammunition, fuel canisters, etc.


Our first pack systems in 2014 and 2015 used the “Skeleton” name for the frame. Our next generation of packs released in 2016 was named K2, then K3 was launched in 2019, and our current K4-generation of packs was released in 2023.

Each generation of pack systems had a frame named after that generation (Skeleton, K2, K3, and K4), and also had bags built for that specific frame.

The changes between each generation of packs has varied. For example, K3 was a refined and improved version of K2, with new and improved features, but K3 shared a lot of compatibility with K2. However, K4 has been completely redesigned from the ground-up and is not just an “improved” version of any of our previous pack systems.

Although we have stopped selling complete K3 Pack Systems, we still offer individual K3 Products to support the thousands of K3 pack owners that may want to purchase additional bags, accessories, or need to change sizes.

Since we are continuing to offer K3 products to support K3 pack owners, we will not be putting K3 on closeout.


Prior to K4, there was a lot of cross-compatibility between Skeleton, K2, and K3 products. In general, K4 products are not compatible with any previous generation, and vice versa. You cannot put a K2/K3 Bag on a K4 Frame, nor use a K4 Bag on a K2/K3 Frame.

There are a few instances where there is cross-compatibility with accessories between K3 and K4…

  • K3 Accessories that will work on K4 Packs: K3 Stash Pocket, K3 Rifle Carrier, K3 Bow Carrier, K3 Dry Bag
  • K4 Accessories that will work on K3 Packs: K4 Stash Pockets, K4 Rifle Carrier, K4 Dry Bag
