This backpack is a very good, quality and enjoyable solution!
I Salomon fitness skates Gr. 44 and they fit loosely in the side pockets outside. The skates are then fixed and tidy and you have a large center compartment enough space for example, training pants, shoes and NEN sweater or the like. I find that an external skate accommodation advantages here.
The shoulder straps are well padded and have 2 cross belts (one at shoulder height and a lap belt). When all this closes match (especially the lap) disturbs nothing more to skate pleasure !!
I'd buy him back to me, because the backpack is well made but I do not think I need that again ;-)
