There are two things about these onbuhimos that are very different from any other carrier of this type (i.e. carriers without a waist belt). The first difference is that the back panel is shaped for the bum of the wearie and creates a deep pocket itself – everyone who ever tried an onbuhimo must realize how difficult it might be to create a deep pocket with a big heavy wearie on her/his back in an ordinary “onbu”, while in case of Mirkine, there is no need for this struggle. The second big advantage of this carrier (and what makes it truly unique) is the chest buckle on rails – the same ingenious rails I love so much and praise all the time in the Kavka Multi-Age carrier! In an onbuhimo, this type of chest buckle is especially great, because onbu is a carrier designed for wearing on the back, therefore I am twice excited about it in case of Mirkine! To be clear – “ordinary” carriers have the chest buckles attached to the shoulder straps by loops that encircle the padding of the strap and when wearing, whether you want it or not, the padding tends to deform more or less in every single one of them. However, not the case of the rail-attached check buckle and no need for me to suffer and endure the deformed shoulder straps pressing on my chest! And in onbuhimo in which the whole weight of the wearie lies on the said shoulder straps, this is twice as important.
