Question: Could one of these fit a 15 inch laptop?
Document: I went with the reviews here on Amazon, and they didn't let me know. As others have said, these are very good panniers for the money. I use them to commute to work, and on one side I can put my laptop case (which is a full bag itself, not just a sleeve for my laptop), and then I've still got room on the other side for other things.
I purchased these bags for my commute to work. They are the perfect size for my intended purpose. I can fit: a change of cloths (including rain gear), pair of shoes, laptop, bicycle repair tools,  and some other random things. Mounting and dismounting is extremely easy (takes about 5 seconds)and when they are mounted they feel very secure. My size 10 feet have plenty of clearance when peddling.
These panniers are the perfect size for a 4-5 mile one way commuter. one bag can hold my laptop, and the other, my lunch, with plenty of room to spare for misc items.Constriction seems to be well done, of course, time will tell. However, nothing feels, looks, seems to be poor construction.
I just wish they had more compartments to isolate your stuff rather than just putting it into the bag. It has a small pouch for keys and a place for my notebook but could use one or two small compartments for other things.
I called the Western distributor! They couldn't answer this either . . . for gawd's sake. I went to several large sporting goods and bike stores, to find one I could measure &#34;in person&#34;. Hmmmm, no one stocks these--is there a message here? The Amazon site even told me how to calculate cubic inches . . . very helpful IF I knew any of the basic dimensions.
First, it clips on and off quite easily. It has a middle clamp that automatically locks it onto the rack so it doesn't fall off the rack. The clamp is like a clothespin so you have to press the clamp to remove it. I only use one bag at a time and just carry lunch, a notebook, and small items like a cell. Once in awhile I'll carry a shirt in it. If I used two I could carry my pants, shirt, socks for a change at the office.
There are of course better panniers out there. However these Avenir Small Panniers are just what I need. For a mountain bike it is easy to get panniers that are too large causing heels to strike the bags. Mine fit the bike well and are a decent size without overloading the bike. Cooking equipment goes in one bag; food and miscellaneous in the other. Tent and sleeping bag on top of rack and a small pack on my back and off I go.I like the bags.
Fit my bike perfectly. They were a lot more shallow than I owned previously, but with a little adjustment I am able to fit a moderate shopping trip in them. I did purchase the  excursion rack-top bag to make up some of the square inch loss; exceeding the large excusion panniers measurements (I now have 2,294 SQ. inches). Together they are a great set of three bags. Too bad some vendors don't catch on and sell them as a full set.
While the Avenir small panniers are exactly what the ad's explanation is, I now wish that I had gone with the larger set. It does hold my Dell laptop - but just barely.
Works great as advertised and are tough too. I would reccommend them for any bicyble commuter. They hold enough for a change of clothes, lunch, bike repair equipment, a laptop and a book to boot.
Answer: yes
