Designed for children from 6 to 10 years old, the equipment consists in a backpack and a lunchbox. The backpack has three compartments: main (for notebooks, books, pencil case), the auxiliary (for toys, clothes) where there is place for utensils, hygiene, and an expandable for the lunchbox. When it is not in use, a rubber band assists in reducing and the backpack can be closed normally. Made of polyamide, with parts in foam, EVA and fabric Drylex, has handles in "s" shape, girths, compression tapes and side pockets. The cover protects the contents and is intended for child's creativity, since it can be personalized with photos, stickers, markers. The outside case helps to access the materials that will be used here, incorporating practicality. 

The lunchbox is thermal and has three layers: polyamide, polyethylene sleeving and PVC film. A division inside can accommodate a bag of gel. The handle with regulator facilitates their individual transport. This system facilitates children's movements, as it keeps their hands free from single items and enables carrying the lunchbox without compromising the material and facilitates cleaning. 

The name "Muchi", as well as its visual identity, are creations of Norberto Bozzetti.
