I originally ordered this pack for a photographer friend but when I opened it I decided to keep it for myself! It has every secure compartment one would ever need and could be used for a wide variety of purposes. The pull-tabs are very sturdy and will stand up to intense and frequent use. It has a top compartment with a hard covershell for breakable items that zips shut with elastic string and clasp. Each zipper is also covered and protects the zipper and addsmore protection for items in the pack. Two pockets in the front, one has tons of different compartments for various items. The front hasan opening in bottom of the pack that you can be access items in the bottom of the pack. The sides of the pack have straps to hold itemsas well as pockets that can be synched shut. One side has plastic name cardholder. The back has padded, select a size straps that canbe strapped securely on. Inside are more Velcro shelves! There is a very padded packet that any size laptop would fit securely in and bevery protected, and more zipper compartments. The Velcro “shelf” can be removed if you want one large compartment in the backpack. Thestraps even have zipper pockets for cell phones etc. There is also a fold out pocket from the bottom that a tripod could be placed andstrapped to the pack for safekeeping. The bottom of the pack has 2 sturdy rubber feet to keep the pack up off the surface and standupright. The waist pack has padded adjustable straps as well as a handle. Inside are more removable Velcro separators as well as anadjustable shoulder strap. Even comes with a very durable elastic edged rain cover. Every time I look at it I am surprised by another pocket or compartment! I would defiantly recommend this backpack!
