Last year, it was announced that popular fashion designer Raf Simons had created a partnership with bag makers Eastpak on a series of modern and creatively unconventional backpacks. To compliment the designs, the backpacks also include several technical features. A portion of the “Material World” collection has landed at oki-ni. The four different styles carry a price tag not for the faint of heart ranging from £179 to £319 (approximately $348 USD to $621 USD).
