Each PLANETBAG product is very lightweight (weighs well less than 1 lb.) – for example, the EVERYDAY PLANETBAG (shopping bag/carryall/tote) weighs approximately 1.2 ounces. The EVERYDAY PLANETBAG and many of the other PLANETBAGs can fold or be bunched into approximately a fist-sized or otherwise small ‘ball’ (depends on the size of your fist!), or slightly larger ball for the largest of our bags – the XXL PLANETBAG.
