Nanobag is a brand known for its ultra-lightweight and compact reusable tote bags. These bags are designed to be incredibly portable, folding down to a tiny size that can easily fit in a pocket or purse. Despite their small size when folded, Nanobags are surprisingly durable and can carry a substantial amount of weight, often up to 30 kg (66 lbs). They are made from a custom-designed diamond ripstop fabric and feature reinforced stress points for added strength.
