Peter loses his backpack so often that Tony starts to carry one of his own with all the Spidey essentials whenever the two are out and about or on missions.

It has noise cancelling headphones, sunglasses, sunscreen because Peter burns, an extra phone, snacks for if they get caught up somewhere where Peter can’t eat every hour because of his metabolism, and a first aid kit.

Clint calls it his diaper bag and Tony just scoffs as he flings the super expensive and designer backpack over his shoulder before boarding the quinjet.
