Hey, I know that this thread is 3 years old and I'm sorry to re-awaken it, however, I've checked around at several online and brick-and-mortar retailers and haven't come up with a good answer yet.
Can anybody suggest a good case for MPB 13" Retina? I stopped by a retailer today and looked at a Thule Gauntlet sleeves... What a joke. The v3 one might be better but the (v1?) version I looked at had zero padding, basically just a piece of plastic to put over your notebook. The Pelican 1085 is larger than I need by almost two inches internally both x and y, and the 1075 is too small. Externally, the 1085 is too big to even fit in my backpack. It's probably also monstrously heavy, though that matters less to me.
The g-form linked above looks good, and probably what I'll buy if I don't get a response, but the cnet review suggests that the corners / edges might not be super safe. I'm a motorcycle (and bicycle) rider; the front of the bag (facing backwards when it's on me) usually has a scarf, hat, etc. To cushion any impacts, along with the air trapped in the bag's main compartment and pouches, MOLLE webbing, and perhaps 3 or 4 additional layers of fabric, netting, etc. Not worried about that. But the sides and bottom where there is a single or two layers will be in bad shape if I lay my bicycle or motorcycle down.
My current case, a cheap-a** monoprice neoprene pouch, has a zipper on one side (which is the case with the g-form as well) which I wager is bad news during any impacts on that side.
Anybody have any more suggestions? It's 2015 and all I can find are these stupid neoprene pouches!
