While the only criticism Chris Hough had while reviewing the Raidlight Responsiv 10L was that it bounced a little when almost empty, the solution is to go for this, the 3L version.  With all of the same important features, but stretching to accommodate mandatory kit, instead of inviting the kitchen sink.  For comfort, stability and ease of use.  There really is nothing better.

A stretch fit, 3L option that will hold phone and keys, or everything you need on a long training run in the summer.  Well supported ultras with stations every 5 -10miles would be a breeze*.  Until you need spare layers, shelters or larger items in general, this might well be your new favourite pack...

*if properly trained & motivated obviously.
