Frequently Asked Questions


  • Q: Are all of KUIU’s pack bags Modular?

    Yes, the ICON Pro and ULTRA pack lines are built to work on the same California made Carbon Fiber frame. Using the exact same attachment points, the ULTRA and ICON Pro bags and suspension are completely Modular across both lines. You can easily use an ULTRA bag with an ICON Pro suspension, or an ICON Pro bag on an ULTRA suspension without any additional pieces needed. Purchasing one frame and suspension and choosing your desired bag size can cover you from short day hunts to extended expeditions.

  • Q: How is the ULTRA Pack different from the ICON Pro?

    The focus of the ULTRA pack line is to minimize weight without inhibiting performance and functionality. A simplistic design, 330 Denier High Tenacity CORDURA® fabric, and removable straps help keep the weight as low as possible.

    The focus of the ICON Pro pack line is to offer you a feature rich pack, that offers durability and organization with a low weight penalty. Utilizing a durable 500 Denier CORDURA® fabric, extensive internal and external pocketing, and an internal lashing system provide the perfect pack for demanding hunts.

  • Q: Why should I care that you use a Carbon Fiber Frame, and what is Spread Toe?

    The patented California made KUIU Carbon Fiber Frame represents a significant step forward in comfort and performance of backpacking frames. The internal structure of the KUIU Carbon Fiber Frame has changed significantly with the introduction of Spread Tow carbon fiber technology. Traditional carbon fiber fabric construction uses round strands of carbon fiber woven together into a sheet, giving it the signature checkerboard look. With Spread Tow technology, the carbon fibers are flattened, laid parallel, and stitched together, giving increased strength by eliminating pockets of weaker resin material. Spread Tow sheet angles can be offset to change the rigidity and performance of the fabric. The patented, molded KUIU Carbon Fiber Frame includes a complex internal structure of foam core, offset and straight Spread Tow layers, and stacked truss supports to optimize strength and flex as needed throughout the frame. At a mere 11 oz., the KUIU Carbon Fiber Frame, included in the Pack system, is a must-have for any mountain hunter.

  • Q: What is the best way to clean my pack?

    Cleaning your pack is easy. You will want to start by removing your bag from your frame (see steps 1&2 of “How do I switch my bag”?). Once your bag is removed make sure all contents are out and the bag has been shook and emptied of all debris. Leave all pockets open. If your washing machine is a prized household possession you can hose out any large debris, as it could damage some washing machines. Place pack bag in washing machine with your detergent of choice. Wash pack in warm water on delicate cycle. Hang pack in a warm area to dry. Refrain from using the dryer, as this will protect the pack and its hardware from unnecessary heat and abuse.

Size - Choosing the right size bag

  • Q: How do I choose the right bag?

    KUIU offers a wide variety of bag sizes to meet the needs of your hunt. The first thing most pack shoppers tend to get hung up on is size. As a general rule of thumb, it’s better to err on the large size- especially in packs that have the ability to compress down evenly by using external straps. The weight difference between our same-model packs within a couple thousand cubic inches apart is minimal, since the additional size mainly consists of extra fabric. In short, bag size selection is not the place to cut weight. Amount of gear carried and time of year/ weather used should be the top two factors in size selection, with duration of your hunt being the third. Although “number of days” is the emphasis around choosing the correct size pack, aside from food, gear volume for a 2-3 day outing shouldn’t be drastically different than the same trip would be for 7-10 days. Referring back to time of year, users who plan to live out of their pack in cold weather should consider the additional volume required for more and warmer clothing.

fitting - making sure your pack fits

  • Q: How do I know what size hip belt I need?

    We have two different sized hip belts, a S/M that will fit a waist size up to 34” and a L/XL that fits a 34” up to a 42”. When choosing your hip belt size, don’t forget to take layers into consideration for total waist size.

  • Q: How do I know what size frame I need?

    Frame size is based on your torso length. We offer three different frame sizes to fit a wide range of torso heights. Our shortest frame is the Regular which fits up to a 17” torso. The Tall fits 17” – 19” torsos, and the Extra Tall fits torso lengths 19” and up.

  • Q: How do I measure my torso correctly for the frame?

    To correctly measure your torso, place your hands on the top of your hips with your thumbs pointing toward each other across your lower back in a straight line. Measure from that line up your spine to your 5th vertebra. The 5th vertebra is the large, protruding bone at the base of your neck. This length is the measurement you will use to choose the correct frame size.

  • Q: How should my pack fit when properly adjusted?

    We advise loading your pack with 20-30 lbs for proper fitting. Loosen the waist belt, shoulder straps, and load lifters completely, and then put the pack on.

    • step1:

      With the top of your hip bones roughly centered or just slightly below center of the hip belt, tighten it as if you were about to begin a hike.

    • step2:

      Snug the shoulder straps down enough to provide solid tension without causing the waist belt to slide up from its position on the hips. Connect the sternum strap and tighten to desired fit. Up to this point the load lifters should still be completely loose.

    • step3:

      Now reach up behind your ears and slowly engage the load lifter straps until all slack is out of the webbing, but do not over tighten. Use a mirror to check for constant, gentle contact between the shoulder straps and your body from the back all the way over to the collar bone area. A small gap here or there is okay, but no more than a finger-width.

      If a large gap appears above or on the back side of the shoulder, remove the pack and move the shoulder straps down on the frame. On the other hand, if the shoulder straps are pressing hard over the shoulders and the waist belt feels like it wants to slide up your torso, the shoulder straps likely need to be moved up on the frame. These upward and downward adjustments are done by simply separating the hook & loop portion and sliding the shoulder straps in the T-Lock slot.

      We recommend making adjustments in 1-inch increments to slowly fine-tune the fit.

    • step4:

      When the shoulder straps are adjusted properly and the frame size is correct for your torso length, the load lifter straps will be at roughly a 45° angle from your collar bone area up to the top of the frame stay.

      If the load lifter angle is too flat, you may need to go up in frame size. On the contrary, a load lifter angle too steep may mean you need to go down in frame size. These load lifter angle details should not be analyzed until the proper shoulder strap contact scenario described above is achieved.

  • Q: If I don’t have the right size frame or suspension can I exchange them?

    Yes, simply contact customer service and they will help you make your exchange and get you the right size. Call: (1-800-648-9717) or Email:


  • Q: How do I switch my bags?

    All of our bags are interchangeable on any frame and suspension.

    • step1:

      Start by unclipping your side compression straps, and load lifter straps from the bag.

    • step2:

      Unclip the load stabilizer straps at the side of the hip belt, and the lower bag attachment straps from the bottom. Your bag should then lift off the frame.

    • step3:

      To put the replacement bag on, start with putting the top stays of the frame in the stay pockets on the top of the bag.

    • step4:

      Connect the lower bag attachment straps and pull till the bag is tight to the frame. Make sure to tighten these straps equally, if one is pulled tight before the other it can cause the hip belt to rotate and become crooked

    • step5:

      Reconnect all the rest of the hardware and load lifter straps till the bag is fully secure.

  • Q: What is a Load Sling and how do I use it?

    Our Load Sling gives you the ability to carry gear, meat, or anything bulky between the frame and the bag. This is really handy when your bag is full of camp and you need to take out a load of meat.

    • step1:

      The first step is to disengage the load lifter straps from the bag. Then from the bottom of the pack, slightly loosen the lower bag attachment buckles that are pulling the bag tight to the frame. Don’t unclip these, just loosen enough to lift the bag off the frame. Disconnect the side compression straps.

    • step2:

      Now keeping the bag and frame in a V shape, place what you are carrying in the load sling down into the bottom and reconnect the side straps and pull tight to secure the load. Using the bridge straps (straps going through holes in top of frame) connect the load lifter straps to the buckle on the suspension side, and the tale side connects to the bag where the load lifter was connected before. Pull all the straps tight to secure the load and you are ready to pack out.

  • Q: How do I attach my Gun/Bow Holder?

    On the bottom of all ICON Pro and ULTRA packs there are webbing loops in each corner of the bottom panel. This allows you to connect your Rifle/Bow Holder on the left, right, or back of the pack. Your Rifle/Bow Holder come with a top strap that has a quick detach buckle to allow you quick access to your weapon. This buckle should be located on the body side of the bag when properly set up.

    For Bows we recommend going through or wrapping this strap higher up on the bow to create downward pressure on the bow to keep your cam secured into the foam buckle.

    For Rifles we recommend making a full wrap around the barrel to prevent the rifle from sliding back and forth.

  • Q: Is there any way to attach heavy items inside the bag?

    This is an option only on the ICON Pro bags (except the 1850). There are eight internal webbing loops that come installed with four extra removable compression straps. This internal lashing system is perfect for securing heavy item inside your bag to keep them high in your pack and over your heals.

  • Q: Can the lid be removed?

    Yes. Four cinch straps, two on the front and two on the back can be unclipped from the bag. In the back center, there is a small oval buckle that is sewn into the lid. The bottom of the buckle has a break in it that will allow you to fully remove the lid.

  • Q: I can’t keep my bag on the top of the frame, why?

    This is most likely due to having the lower bag attachment straps hooked up to the incorrect loops on the bottom of the bag. If you look up the back of the bag another 4” there will be another set of loops that will give you enough pull to tighten the bag and prevent it from coming off the top. You will only have this issue on pre-2017 ICON Pro and ULTRA packs.

  • Q: When do I need an adapter kit?

    Due to hardware updates to our 2017 packs you may need to contact customer service to acquire the appropriate adapter kit for your pack. If you purchase a new 2017 ICON Pro or ULTRA bag to put onto a pre-2017 suspension you will need to get an adapter kit #1. If you purchase a new 2017 ICON Pro or ULTRA suspension to use with a pre-2017 ICON Pro or ULTRA bag you will need to get an adapter kit #2. If you need further assistance on which adapter kit is appropriate for your current set up, please email pictures of the hardware that you have to and we will make sure to get you the correct hardware.
