I know similar questions have been asked before, but my request is fairly specific, so bear with me. I just acquired a MacBook Pro, and I'm looking for a sleeve. I'm an active student as the title suggests, and I will be carrying the MBP with me almost everywhere I go, either in my Swiss Gear Maxxum Laptop Backpack, or my generic messenger bag (not made for laptop). I want something that will protect the MBP from things such as small bumps while in the back, pressure from textbooks or other materials, and scratches. I also want something that fits the MBP fairly tight, and doesn't add too much bulk. I've already tried the inCase Neoprene, but I found the fit too loose for the MBP. Once again, just looking for a basic sleeve, no handles. Any suggestions?
