A new POC enduro race specific hydration backpack is built around a lighter-weight foam back protector, a requirement for some races like in France, for example. It features 13L storage capacity and the back protector can be removed. There is also a minimalistic protection + water version, which basically just holds the back protector and carries a small amount of water and some basic tools.
