This is made of yacht sail material that is called spinnaker. It is a very light and durable material.
It makes a rustling sound at first, but after use, the sound becomes less noticeable and the material becomes softer.
Larger A3 size.
The opening is designed to be wider than the bottom for easy entry. The bottom gusset is not provided to make it easier to insert the bag into a gap in a rucksack.
