Blue is a great colour, and a fine match to many a school uniform or sports kit.
But colour isn't everything. First, take our word that this is a fine, quality product. The ball shape is maintained by moulded EVA foam so holds its shape, the interior has pockets for phone, pens and valuables, and the back of the backpack is generously padded, with two comfortable and adjustable shoulder straps and a strong top carrying handle. We particularly like the chunky, strong white zip.
Capacity-wise, it'll take money, water, snacks for a day out, or work as a boot bag for practice.
Is it practical? This is no lightweight. Let it play out, then just wipe it down. Sorted.
And it is a great colour.
