The Leatt Hydration Core 1.5 is a solid hip bag for fair money. The interior is well structured and the hip bag is overall pleasant to handle, except when you want to loosen the tension on the hip belt. The only disadvantage is the small volume, which offers just enough space for the bare essentials when the hydration bladder is well filled. The use of bottles not only makes the hip bag versatile, it also creates significantly more space inside. The disadvantage is that large bottles can wobble in the holder. If there is a lot of content, the hip bag itself wobbles a bit.
