As devoted adventure cyclists, we design with our fellow riders in mind, creating products that address genuine needs and bring new value to the bikepacking scene. We create the best packs we can, using technical materials and precision crafting techniques – and when we find a way to improve them we do so straight away and without fanfare. We don’t do ‘seasons’, limited editions or discount our gear – we simply create the best possible technical bikepacking gear that’s built to last.
