ive got a set of wolf kangaroo. its great, light, comfotable warm with its little fleece in an cool with out it. ive a few friends with both the one a two piece they all like it to. Duno about their others but mine has got schoeller armor and ive seen that around a bit. it didnt come with a back protector but i prefer to source one suited to me any way. mines solid and ive no complaints.
