Rated 5 out of 5 by from The One Bag to Rule Them All This is a great bag! I use it daily for commuting. It's by far the best designed computer bag I've owned. I use it every day during the week, but I like it so much that I am starting to reach for it for weekend adventures as well! After years of messenger bags, I'm now fully committed to backpacks. They spread the weight better and are far more comfortable. I went through several competitors including Chrome, but none were the right mix of water proof, functional and comfortable. This bag has it all: comfortable straps and frame, rugged materials, a stash pocket, an organizer pocket, and a spot for sunglasses up top. The key lash is long enough to access your keys while holding the top handle. It also has side water bottle pockets and a great spot for a u lock. The bag has a narrow profile, keeping the weight of the load close to the body. I also really like that it sits below your shoulders. This is in contrast to many roll-tops where your rear field of view is blocked when looking over your shoulder. Both the sternum and waist strap are detachable. My preference is to only ride with the sternum. The laptop sleeve sits closest to your back. I also like that it doesn't scream bike bag. The style is muted (at least the black) - a bit stealth which I prefer. It's a great looking bag suitable for office environments. It has built in reflective panes that look like design details during the day, but lights up at night. It's also an easy bag to travel with. Fully loaded, I can get a days' worth of shoes, clothes, food, and the laptop packed in with no issues. It also rides very well when lightly packed. The compression straps, along with the side zippers help the bag expand to accept a helmet. The build quality and materials are also excellent. I have no doubt that this bag will stand up to abuse. Plus you have the Timbuk2 lifetime guarantee if anything does happen. Overall, I'm really happy with this backpack.

Rated 5 out of 5 by from Lays Flat My Timbuk2 Especial Medio was worth the wait. I ordered in late December 2014, and I it arrived in late January. REI requested it from the manufacturer. At one point REI offered me the opportunity to give-up on the order, but I persisted. The Timbuk2 site is now listing only 9 bags left. If I lost it, I'd definitely be tempted to replace it. I'm curious if there will be another mass order or a re-design. Please check out the Timbuk2 product videos for the entire Especial series. This bag makes sense in context. The Medio's external side pockets accommodate either U Locks or beverage containers. This was a risky strategy by the designers, but in practice it actually works. I've had no problem keeping a 24 ounce Polar Bottle on the side with the additional strap. If I could change one thing, I'd ask for the extra beverage strap on both sides. I'm limited to 12 or 16 ounce bottles on the smaller side. The material on the external pockets is not as elastic as I hoped, nor as elastic as other bags from other manufacturers, but once the bag is in use, moderately filled, the pockets work. I'd say the primary design advantage to this bag is a low profile. It lays relatively flat on my back. The shape definitely works for cycling, but it's also important to me on public transportation. This bag is the replacement for the dreaded hump-back backpack, think Swiss. The various compartments compete with one another for space. I read this from other reviews on the web. It's a trade-off, and it's perfectly acceptable. I want a low profile, and the bag forces me to keep a low profile. The one glaring exception is the middle, external pocket, with the zippered extenders open. I think this big pocket is designed to keep a wet raincoat or helmet separate from the dry internal items. For me it's a good spot for slightly greasy and clumsy U-Lock and cable combination. As an added bonus, I found that I can temporarily carry around a pair of dress shoes in this open pocket, as long as I don't mind them being exposed to the elements. When I get to my destination I need to prop up this bag on a chair or lean it on a table leg. It really doesn't stand up on its own. I'm considering adding rubber pads to the bottom to make it stay still. I hate to complain; it's an amazing bag. I saw a comparable Timbuk2 in a local retail store with standard zippers, but the water resistant zipper covers convinced me to hold out for an Especial. I browsed for each Especial bag and the Medio was my undisputed favorite. Since day one I've been very happy with it.

Rated 5 out of 5 by from I wanted to LOVE this bag but it didn't fit well This was a bag I wanted to LOVE. The large capacity with lots of options for smaller storage were exactly what I wanted. The weatherproof (waterproof) was what put this bag on the top of my list. In Seattle, where it drizzles a lot during parts of the year I find myself having to stop my ride to put on my rain cover and this was the perfect answer to that problem. I worked past the lack of hydration pocket by using the compartment designed to expand for helmet storage to hold my water bladder & routed the tube out the (existing) hole at the side under the velcro flap. There is no drainage from that pocket so if it leaked (or if you put a drippy wet helmet/jacket/shoes in there) it could be a bear to clean The inside portion is HUGE! Lots of room for storage of everything (though whatever you find you need will always be at the bottom!) There are 2 handy little pockets on the inside front of the main pocket that were handy for quick access items that didn't fit in the smaller compartments in the very front organization area. The laptop space is well padded and the retention strap is very long which would allow for a wider laptop to be placed in there. The front organization area is very tight to access, especially if the main compartment is full. That bit aside there is some nice organization options there and a nice flat pocket behind that which will easily hold a tablet or book. The huge downside to this bag was the shoulder straps. They are very narrow and were rubbing on my neck (on both sides) from the first ride. I thought I would get used to it or the pack would break in and the padding would relax a bit but no luck. I am 5' 2" and fit in a standard women's day pack easily but unfortunately this didn't work for me. I had to return it and the search continues...

How does it hold a 15 inch laptop when the longest dimension is just over 13 inches?

Asked by: maamhikesalot
The dimensions for a 15 inch laptop are taken diagonally. The Especial Medio can fit a 15 inch laptop.
