Weekend Warrior’s recommendation : Quite frankly I do not know what to say…. you clearly know what you are doing (or not) if you are looking at these type of packs! They do have an awesome amount of packing space and a plethora of zippered pockets. Designed and constructed for big stage races and self supported races. This pack will serve you well for races like Skyrun, Karkloof 100 and the like.
