Vaude's Roomy bike pack is full of well thought-out touches, finds BikeRadar.
There's a removable zip purse which clips to the top of the bag, a fluffy pocket for media devices and phones and a clip-on helmet hammock.
There's also an eye-catching rain cover, zip and mesh pockets to provide plenty of storage and a beautifully soft harness. This works in conjunction with the wired back system to be as comfy under sleeveless jerseys as it was under two layers of thermal and waterproof.
Our only quibble is that the access from bladder pocket to the outside world is via a very tight gap right at the top of the bag.
