It's easy to see why this Maxpedition Multi-Purpose Bag (MPB) costs a bit more that others I've looked at. It is manufactured with a heavier gauge fabric (1050-Denier water and abrasion resistant light-weight ballistic nylon fabric) that is treated with 3 coats of polyurethane and Dupont teflon fabric protector , and the seams are double-stitched with high-strength composite nylon thread and taped and finished. The straps for the handles wrap all the way around the bag and come up the opposite side as 1 piece rather than simply sewing on 2 separate straps for the handles, adding tremendous strength when the bag is carried with a heavy load. All stress points are also double stitched, Bartacked or "Box-and-X" stitched for additional strength and protection. The zippers and tracks are all heavy-duty reverse-faced YKK brand for long-wear and strength under heavy loads and stress. It also has a 2-inch strap with a long pad that does not slip or turn over. I have the khaki bag, probably the best non-descript color choice for tactical and theft prevention purposes. It comes with the CCW strap Velcro holster and the 3 magazine Velcro strap that both attach to the Velcro-enabled removable main compartment divider. The padding is high-quality closed foam material that absorbs most bangs and bruises pretty well.
Good thing, since I have a MacBook Pro, IPad, Flip HD, cell phone, associated chargers and cables, Springfield .40 XD SubCompact, .40 ammunition, maps, X2 Tactical light/Laser, Surefire tactical light and extra batteries, Garmin Colorado GPS, regular AAA and AA batteries, Zagg portable charger, Celestron sports binoculars, specialty batteries, Ranger Buck Knife, Hoffritz Sailing Knife, Stubby Tool Set, 1 Mag Baton Light 4-D-Cell, Mini-Mag, Work Gloves, Pens, Pencils, Moleskine notebooks, matches, firesteel, Husky Metric and Standard Allen wrench sets, sewing kit, toiletry kit, Datrex Emergency food bars, water purification tablets, reflective blanket, emergency shelter tent, first aid kit, light sticks, military compass, military map grid tool, survival manual, solar charger, rechargeable batteries, and a portable emergency wind-up radio packed into this 1 bag! I'm still putting more items that I find out I forgot as I go along.
Highly recommended bag. This one should last me a few years.
