Winner = Tomantek is my choice https://www.amazon.com/gp/product/B073QFMPK1/
I recently bought an m15 and spent WAY too much time searching for a case/sleeve for it. Hoping to save other m15 owners some time.
I was having trouble finding one that was large enough to accommodate the unusual dimensions of the m15 AND yet also be small enough to fit in my Wenger Synergy backpack's designated laptop pouch.
Wenger Synergy Backpack, Gray (GA-7305-14F00)
I eventually found 5 cases/sleeves that the m15 would fit in, but some were just too wide for the backpack. And by “wide” I mean, when stored rotated 90-degrees, it would stick out and I could not zip closed my backpack. Either way, I'm going to share my results for other m15 owners...
These are the 5 sleeves I bought for testing:
1. ZinMark Laptop Case Sleeve 15.6-Inch, Spill-Resistant Protective Case for 15.4-Inch MacBook Pro A1286 / Retina A1398 and Most 15.6-Inch Laptop Ultrabook Netbook, (15.67 x 11.02 in) Dark Gray
2. Lacdo 15.6 Inch Laptop Sleeve Bag Compatible Acer Aspire/Predator, Toshiba, Dell Inspiron, ASUS P-Series, HP Pavilion, Lenovo, MSI GL62M, Chromebook Notebook Carrying Case, Water Resistant, Gray
3. Evecase Laptop Sleeve, 15~15.6 inch Diamond Foam Splash & Shock Resistant Neoprene Universal Sleeve Zipper Case Bag for Dell HP Gaming Chromebook Ultrabook Notebook - Black
4. MOSISO Laptop Sleeve Bag Compatible 15-15.6 Inch MacBook Pro, Ultrabook Netbook Tablet with Small Case, Shock Resistant Diamond Foam Water Repellent Neoprene Protective Carrying Cover, Black
5. TOMANTEK [Best Comfortable Laptop Sleeve Ever] TOMANTEK 15-15.6 Inch PU Polyester Slow-recovery Sponge Shockproof & Water-resistant Laptop Sleeve Case Bag/Ultrabook Laptop Tablet Bag Case/Skin Cover, Black
Note: For comparison purposes, my particular m15 laptop weighs exactly 5lbs, 1.0oz (2.3kg).
The Zinmark is a nice dark gray with two metal zipper pulls. The opening extends on the long edge. It has a nice furry interior and an extra zipper pocket running the full height of the sleeve. I like two zippers over one because it allows me to zip it closed with an AC adapter still connected. Plus, if one zipper breaks, you're not screwed. Unfortunately, there is some resistance to zip it closed due to the depth of the m15 (measuring from the front to back of the laptop), so it’s a bit tight there, and at 16" wide, it doesn't fit in my backpack.
Weight = 8.7oz (246g)
Total weight with m15 laptop = 5lbs, 9.7 oz. (2.54kg).
I like the Lacdo a lot with its extra pockets (two zippered pockets on front + one pouch on the back. It’s great if you just carry your laptop around or have enough room in your backpack/briefcase for it. But at 16.5” wide, it wouldn’t fit in mine. Plus, you really are limited to slim items in the zippered pockets (pens, notebooks, USB drives, etc.). A travel mouse would add a lot of bulk (unless you have the one from Microsoft that folds flat – that’s what I use). Two metal zipper pulls plus a soft felt lining with no tags inside make this an ideal case for an m15 owner that wants the ability to store and carry other items including files folders and documents. Those extra pockets do add significant weight, though. It’s the heaviest of the bunch.
Weight = 11.4 oz (324g)
Total weight with m15 laptop = 5lbs, 12.6oz (2.63kg)
The Evecase is great, if you don’t mind neoprene. The thick pyramid-shaped exterior pattern offers good crush protection, but since it’s only the points of each pyramid are what come in contact with whatever surface it’s on, it slides around easy, such as on a car seat. Being pointy neoprene, it’s quite flimsy when empty and, quite thick when a laptop is stored inside. Also, an “Evecase” logo is stitched on one side of the soft felt liner. That could possibly cause scratches or wear marks on your laptop over time. While I do like the think rubber zipper pull, there is only one pull, and I prefer two.
Weight = 7.8 oz (220g).
Total weight with m15 laptop = 5lbs, 8.9oz (2.52kg).
The MOSISO is identical to the Evecase above, except it has two metal zipper pulls instead of one rubber pull. It also comes with a smaller version good for a travel mouse, portable hard drive, or cables, etc. It’s much to small to fit in an AC adapter.
Weight (excluding bonus carry pouch) = 7.8 oz (220g).
Total weight with m15 laptop = 5lbs, 8.9oz (2.52kg).
Last, but not least, is my personal favorite/winner. The TOMANTEK sleeve has everything I wanted: light weight (it’s the lightest of the group), two zippers, nicely padded, not flimsy, and fits in my backpack – just barely. It has the most interesting outer texture and feel. It’s grippy, so it wouldn’t slide around on car seats as easily as the others and has this sort of firm/spongy feel to it. While it does lack any extra pockets or pouches, that’s fine with me since that’s what the rest of my backpack is for. The height of the case is perfect for the m15 and with the laptop inside, there is roughly 2cm (one finger width) worth of wiggle room width-wide. While the case COULD be ½ smaller in the width for a snug fit (and a better fit in my backpack), inserting and removing the laptop from such a snug-fitting case could be a bit cumbersome. So, I like the fact that there is some wiggle room width-wise. I also love the fact that zipper teeth are not exposed at all when it’s zipped closed. That could quite possibly help keep out any moisture or splashes. This one’s a keeper for me.
