The MAP 3500 Three Day Assault Pack by Kelty has been the preferred Military Assault Pack of the U.S. Navy SEALs for the past 6 years due to its rugged construction and superior design.

When the Special Operations Forces (SOF) community requested a new and improved assault pack, Amron approached Kelty because of its outstanding reputation as a manufacturer of quality equipment in the outdoor industry. Designed and engineered with the the help of direct military end-user input and feedback at the Boulder 2000 conference, the MAP 3500 is the Commercial Off The Shelf (COTS) solution for a sturdy and functional Military Assault Pack (MAP).

Amron's philosophy is this: You need a backpack; why not have the best backpack company build your pack? Designed to meet the needs of the field, the packs also work as carry on luggage for business travel, fitting in overhead storage compartments on all commercial airliners.

Amron recommends Camelbak hydration bladders for your Kelty pack.

  • What is the proper method for adjusting the strap on the MAP 3500?

    Six Steps to a Great Fit

    Your goal is to have 80% to 90% of the load weight resting on your hips. To achieve this, start by putting about 10 to 15 lbs. of weight into the pack to simulate a loaded pack. Follow the steps below in front of a mirror. Get a friend to help if possible.

    Step 1: Hipbelt

    • First make sure all the pack's straps and hipbelt are loosened.
    • Put the pack on your back so that the hipbelt is resting over your hip bones.
    • Close the hipbelt buckle and tighten it.
    • Check the padded sections of the hipbelt to make sure they wrap around your hips comfortably. Keep at least 1" of clearance on either side of the center buckle.

    Note: If the hipbelt is too loose or tight, try repositioning the buckle pieces on the hipbelt straps. If this doesn't solve the problem, you may need a different pack (or hipbelt).

    Step 2: Shoulder Straps

    • Pull down and back on the ends of the shoulder straps to tighten them.
    • Shoulder straps should fit closely and wrap over and around your shoulder, holding the pack body against your back. They should NOT be carrying the weight.
    • Have your helper check to see that the shoulder strap anchor points are 1" to 2" inches below the top of your shoulders.

    Step 3: Load Lifters

    • Load-lifter straps are located just below the tops of your shoulders (near your collarbones) and should angle back toward the pack body at a 45-degree angle.
    • Gently snug the load-lifter straps to pull weight off your shoulders. (Overtightening the load lifters will cause a gap to form between your shoulders and the shoulder straps.)

    Step 4: Sternum Strap

    • Adjust the sternum strap to a comfortable height across your chest.
    • Buckle the sternum strap and tighten until the shoulder straps are pulled in comfortably from your shoulders, allowing your arms to move freely.

    Step 5: Stabilizer Straps

    • Pull the stabilizer straps located on either side of the hipbelt to snug the pack body toward the hipbelt and stabilize the load.

    Step 6: Final Tweak

    • Go back to the shoulder straps and carefully take a bit of tension off of them. Now you're ready to go!
