I got the medium size and it's a roomy tote with room for a lot more than the measurements would indicate. I got it in red/coral/pink and I love this color combination though it is no longer available. Very well made, strong fabric and washable (yeah!). Will be buying a size small as well in the future.

I own 4 Timbuk2 bags. 2 small totes, 1 medium tote and 1 small messenger bag. The medium Timbuk2 Tote is ideal as a diaper bag. The inside is lined with a great material that wipes out easy. Super durable inside and out. It has a sectional compartment and a mesh slot that is great for a bottle.
On the other side, my messenger bag has been a great work bag. Hold papers without folding them. Not to big, not too small.
I purchased 2 small totes as baby shower gifts. (one in pink, one in blue). But I think I might just keep them. I am hooked on the quality and style - Great Bags 5 out of 5.

Fits perfectly in a gym locker.
Easy to clean and carries all your stuff for a gym workout/trail run.

i have the small and the med. sized and out of all my timbuk2 bags i use my two totes the best. i like the trendier look of it compared to my metro bag!

The Cargo Tote is a bit deceptive from the outside - at one time I have carried several books, a laptop, cords, my purse, music, and many other extras. I really liked the number of pockets available. Unfortunately, when packed to the brink, this tote isn't the easiest to carry. The straps don't have any padding and it can be a bit awkward. For lighter loads or short walks to work, this is very functional and comfortable.
