1. An exoskeleton configured to be worn by a user to support and transfer a load carried by the user across a ground surface; the exoskeleton comprising a torso section connected to a leg section via a hip section so as to transfer the load carried by the torso section down to the ground surface via the hip section and then the leg section, the hip section adapted to be maintained on each user's hip; wherein the leg section comprises two symmetrical articulated leg assemblies, each leg assembly being adapted to be maintained on each user's leg and to follow the leg's movements when the exoskeleton is in use, each leg assembly having a hip connector assembly adapted to be maintained on an outer side of the user's leg and connected to the hip section, an upper end connected to the hip connector assembly, and a bottom end adapted to be maintained on an inner side of the user's leg and in contact with the ground surface, each leg assembly being configured to entirely transfer the load from the outer side of the hip section to an inner side of the user's leg before connecting to the ground; wherein each leg assembly comprises: an upper leg member extending downwardly from the hip section and having an end pivotally connected to the hip section to allow the upper leg member to move with respect to the hip section when the user moves; and a lower leg member extending downwardly from the upper leg member and pivotally connected to the upper leg member, the pivotal connection between the upper and lower leg members configured to be located at a knee level of the user to allow the lower leg member to follow the movements of the lower leg of the user with respect to the upper leg; the upper and lower leg members configured to extend downwardly and toward the inner side of the user's leg so as to entirely transfer the load from the outside of the leg toward the inside of the leg and down on the inner side of the foot of the user.
