The "ND" Packs Explained

You may have noticed some of the packs we sell have the words ND in the name.

The ND or Narrow Dimensions packs are built with different proportions to our Regular packs, making them ideally suited to anyone with a smaller frame. They’re designed to provide a comfortable and supportive fit for women or men with a narrower build.
