The material is a bit thick and stiff but contributes to being more durable. Im used to a softer, more pliable material. The large size is a bit too large for my needs. I usually travel with a duffel bag or carry-on sized roller and the large cube doesnt fit right. The medium, small, and slim are perfect for separating sweaters and pants, shirts, and socks and undergarments. Overall works well for a packing cube.
