flossstuff is the fusion of two simple needs when looking for a backpack. Functionality and style. The PEVA lining makes it easy to wipe away those inevitable leaks and spillages on the bags interior, whilst also serving as a cold or hot insulating liner. Couple that, with the recycled raw linen finish, interior hang pocket and side bottle carriers, the flossstuff backpack is all you or your children need to get outdoors and take everything you need with you.
