The Crumpler Dinky Di Messenger Bag - Dusty Khaki/ Orange is exceptionally well made, if a little small. I guess the clue is in the name, 'Dinky'. It is a 20 litre messenger bag. The removable shoulder pad is large and comfortable. The shoulder strap is easily adjusted and the excess strap tucks very neatly into the side loops. There is a very useful stabiliser strap that moves easily in the shoulder strap and clips to either of the lower corners of the bag. This makes immediate sense if you cycle while wearing the bag because it stops the bag swinging in front of you. It has 3 internal pockets, the middle one securing with Velcro. Also, there is a larger front pocket that has a chunky zip closure. There is a neat reflective strip that runs horizontally across the bottom of the front. Great for being seen at night on your bike etc. It will easily take my 13" Mac-book, a large note pad, my lunch and a jumper. Overall, I am very pleased with this well made, stylish and comfortable bag. If it was any bigger I would only fill it with junk. I love my new bag!
