The Kelty MAP 3500 is a very popular pack with military personnel as well as everyday hikers. In case you are not aware of what MAP stands for it is 'Military Assault Pack'.
This pack was designed and engineered with the help and input of the military, which is the main end user, at the Boulder 2000 Conference. The MAP 3500's are a COTS 'Commercial Off The Shelf' solution for a rugged and highly functional assault pack for the field. Kelty was selected to manufacture this pack because they have an outstanding reputation of manufacturing outdoor equipment.
The name of the game for this pack is adjustability. The pack has 2 main compartments. There is a large compartment and is made up of 3 pouches. One pouch could be used for a reservoir such as a camelback, a second pouch that has elastic and also an adjustable strap and then there is the main pouch area. In the smaller compartment you have a clip for keys, a zippered pouch and slots for pens and the like. There is also a fleece lined pouch to put glasses or sunglasses which is a very nice feature.
Nalgene sized bottles or 32oz Gatorade bottles can be carried in 2 very deep mesh pockets on the side that come up to the caps of the bottles and can then be tightened down so the bottles never falls out. There is also capacity for a 100oz bladder for the hydration system with a hydration port tube that can be used over either shoulder. This hydration port has a snap on the top for closure.
On the outside of the pack there are many adjustments for the shoulders, chest, waist and there are side straps to allow you to cinch the bag on itself. These are the major adjustments. Some of the finer adjustments are the chest strap that can be moved to come across your chest at a comfortable level. The shoulder strap lengths can also be adjusted by using Velcro. The waist strap is a thick comfortable belt that can be removed and stored when not needed. There are also many locations on the outside to attach equipment.
Internally there are two light beam stay rods that are vertical and help to give the bag its shape while helping to distribute the load. The waist belt uses the Scherer Cinch tightening system that allows for very secure adjustment.
Whether you are looking to use this on a military exercise or take it on a plane this pack will suit your needs. Well built and designed, this pack should last even the most ambitious user many years of service.
