No spacesuit (or school uniform) is complete without this mission-ready backpack. There's room inside for all the essentials, and because we know that intergalactic travel can be thirsty work, there's an elasticated water-bottle slot on the side. We've used standout appliqué and embroidery to create not one, but two extra jets – with whooshing flames – to speed up journeys. Contrast-colour straps and branded zips add to the brightness.
