Seek For Chirstmas Idea Suggestion

[HowardLink]

My parents gave me the gift Canon 600D on my 15th birthday. I really like the DSLR, now they said that they will give me a Chirstmas gift and asked me to find the one I prefer. So I found this canvas camera bag (http://www.koolerbuy.com/koolertron-f2001-canvas-dslr-slr-camera-shoulder-bag-backpack-rucksack-bag-with-rain-cover-for-sony-canon-nikon-olympus-p-3882.html). I love the design and the size is right. Does it OK or any other suggestions? I have three lenses now (50mm, 18-55, and 55-250). TKX advance.
