I love 5.11 products but do not buy this bag. It has all kinds of compartments, but after you put a computer in it and a few other items the bag is useless. It is just not a good design. Very disappointed because the construction of the bag is awesome.

This bag is big enough to fit an iPad Pro 12.9 and a MacBook Pro 13, not recommended for a MacBook Pro 15. This bag has a lot of good perks. I’ve made the best choice. Thank you 5.11 INC

After five months of daily use this bag is still keeping my laptop safe and dry, even through a snowstorm and a night of icy rain. And the front pockets are so handy!

It could stand to have just a smidge more depth. As other reviewers have noted, with a laptop in the back there isn't much room in the front compartment.

The over all design is almost perfect for everyday use, and the bag is very well made.

The bag is a little too small for me, and a potential customer might very well find the LIMA bag more suitable for a broader range of activities. A big drawback of the design is the lack of one larger main compartment. It's a compact little bag and it doesn't stretch at all. It easily fits a small laptop and some minor stuff, but loading something more, like a small lunchbox without problem is almost impossible.

Nice and descrete design of the water bottle pockets.

I can definitely recommend this product. Exelent quality!

Says it will fit a 15" Laptop. My 2012 15" Macbook Pro does not fit. Overall the bag is way to small - you cannot utilize the pockets because the depth just doesn't allow for any (other than papers) bulk.

I just got a Microsoft Surface Book. I looked around for a good backpack to carry it in and didn't see any recommendations. This is my submission to rectify that situation.

I wholeheartedly recommend the 5.11 Tactical Rush Delivery MIKE Messenger Style Bag, Black. The Surface Book slips in easily and there's room for the AC adapter and a pocket for the stylus. Actually there's about twenty different pockets (but who's counting). If you have a laptop that's bigger than the Surface Book 511 has larger bags (Rush Delivery Lima, Rush Deliver Xray) but the Rush Delivery MIKE fits a Surface Book perfect.

There's not a lot of extra room in the bag, but you could slip in a tablet, a pad of paper, and a phone if you wanted. There's an external water bottle pocket on both sides. I keep a small collapsible umbrella in one of them. The other will snuggly hold a Thermos 16 Ounce Stainless Steel Commuter Bottle, Silver (available from Amazon). It fits tight (probably wouldn't come loose if I was hit by a truck), but slips out easy. I recommend this container because it uses vacuum as an insulator and keeps liquids hot or cold for hours.

If you do some research you'll probably see some reviews that state the Rush Delivery MIKE isn't expandable. Well, that's true and it isn't. There's a limit to how much you can put in it.

However, like all 511 bags, Rush Delivery MIKE is coated with molle. For those of you who don't know molle is a military grade method of attaching extra stuff to the outside.

511 has quite a variety of things you can attach to your bag using molle. I currently have the Tactical 5.11 Unisex Adult H2O Carrier (which can be used to hold a larger water bottle than the Rush Delivery MIKE side pocket or used for other stuff), the 6.6 PADDED POUCH, and the 5.11 Large Drop Pouch (which is really cool because it folds up to be out of the way when not in use and unfolds to hold a lot. I used it to carry my lunch to work.) I own these items and currently have them attached to other 511 bags I own, but moving them from one bag to another only takes a couple of minutes, so I recommend them.

I am not associated with any military organisation or police organisation or with the 511 company in any way. I sing 511's praises because they make a good product. If everybody knew about 511 all the rest of the backpack manufacturers would go out of business.

The "MIKE" bag is perfect for carrying around my smaller laptop. I love the durability and functionality. If you have a larger laptop or need extra room be sure to get the LIMA or XRAY! The hook and loop is strong and I love it. I think this is perfect for what it was made for. GREAT JOB AGAIN .511

Today receive my Rush delivery Mike bag my 15 inch laptop didn't fit in the describe laptop pouch. Not too happy about that but other than that everything else is exceptional.

My profession takes me from field work to board rooms, sometimes both in the same day. So, when I change from Taclite pants and a Performance Polo to a suit, my beloved Triab 18 sticks out like a sore thumb. The Rush Delivery Mike bridges the gap. My Triab will still see plenty of after work and weekend use, but the RDM is now EDC at work. Now all you need is a business suit with MOLLE inside the coat and a TacTec tie...

The materials and hardware used are top quality. The variety of pockets are very versatile for my needs. I like the bag.

But, like most "tactical" gear from 5.11 and others, there is an overuse of too "sticky" Velcro. (Same complaint for 5.11's Stryke pants.) It should not be necessary to have the upper body strength of a lowland gorilla to pull open the pockets. Please lighten up 5.11 on the Velcro.
