This bag is exactly what I was looking for other then not being a solid grey color, but it's close enough. The main compartment is big enough to hold everything I take to work when I do 4 double shifts. Clothes, shower supplies, food(b-fast/lunch/dinner for 4 days), ipad and shoebox size "tub" of accesories, a few 32oz bottles for water/tea/etc..... Shoulder strap is wide and stays in place no matter what type of shirt/jacket I wear. My regular gym bag I replaced would constantly slip off, not this bag.

There are no amenities like pen slots, little compartments for misc stuff....things that I was NOT looking for. This is a great, solid and rugged bag that will go thru all your uses with no problems.
