Review on Navy JanSport Firewire Core Backpack by Katie Johnson

Build quality is excellent, only the shoulder straps are incredibly short. I used to have Jansports and have never seen this before. The full-length backpack hugged my shoulders snugly. The straps on my other Jansport (Samba Trans) are about DOUBLE as long! How and why Jansport was able to do this I don't understand - another 8 inch straps and I would love this bag - too bad they don't post strap length details on their website, right? If you're a little man, kid or girl you might still be wondering, so let me give you information you probably won't find anywhere else: Shockshield is the hard shock absorber on the bottom of a laptop sleeve. So make sure you drop your laptop bag straight down so it lands right side up, otherwise a shockproof screen won't help you. The padding on the front of the sleeve can be 3/16 inch - quite thin. The lining on the back of the bag, which is also the back of the case, is thicker and more appropriate. My 15.4" Dell Studio protruded about 3" from the top edge of the case, leaving the entire edge unpadded. The sleeve strap is good - you can tighten it as you like. I think this will provide adequate protection, but I wouldn't say "advanced".
