LOWEPRO TRIM TREKKER CAMERA DSLR CAMERA CASE/ BACKPACK. $45 Excellent Condition! You will be very happy with the gentle use, room for everything, and durability of this bag! (I got a new one for Christmas and that is the only reason I am selling.) Approximate size is 13" x 15" x 8" and it holds everything I need for my full size DSLR and multiple lenses and accessories! It's a pack! It's a shoulder bag! The Trim Trekker gives you a choice, with a removable harness that disappears into its own padded compartment when not in use. It's incredibly comfortable as a backpack because the straps are very well padded and there is also a chest clip for extra support and their is a waist belt as well.
