I've had this bag for 3.5 years, I have cycled to work with it at least twice a week, it's very comfortable for cycling and holds in place with the extra strap brilliantly. It's been from London to Jamaica twice (I did not cycle!), to spain and on every road trip I have been on. This bag has been present at the births of my 2 kids, it's now a part of the family... The laptop padding is amazing and protects my mac book pro like a gem. All the pockets are excellent and highly useable. This bag, since being in my life deserves 100 stars. The person who said the quality is bad either had a bad one, or totally abused the bag and over filled? Mine still is going strong.
