Dell XPS 15 L502X sleeve

Hey mates,

I recently bought a Dell XPS 15 L502X (15.6" widescreen - 15"W x 10.4"H x 1.5"D). To protect it, firstly, I got a Deuter Gigant backpack... however, to protect the laptop even better, specially because the compartment of the Deuter fits 17" laptops, I'm looking to an sleeve with some anti-shock protection and, if present, waterproof too...

Unfortunately, here, in Brazil, we don't have so many good choices to chose in our internal market... we have a great number of cheap neoprene sleeves, but only a few models from companies like Leadership, Case Logic and Razer (to name the most easily found)... the unique Leadership that fits the laptop is the 17" one, but it's a bit greater, and probably won't fit nicely... in the case of Case Logic, the models with final 116 should be the ones, but the unique that I found was the QNS-116 áttache, that seems to be a messenger bag, more than a sleeve... the other models, the ones with final 117, would be awesome in the width and height, but are a few thin (1" depth)... and, here, we have the 15" and the 17" sleeves from Razer, but I can't tell much about them, cause neither saw a picture from inside, and even the reviews are scarce...

So, if neither of the above options were good options, I'll try to import, even with the high fees imposed by our government... now, I'm looking for the Zeroshock, but would like to know if there are another good options to choose, even between the companies listed above...

Cheers!
