The total weight of Set of 5 is less than 1 pound, just 15.2 ounces.
The Set of 6 weighs 1.2 pounds.
It doesn't add any extra weight to your baggage.
The material has a polyurethane coating on the inner surface.
Thus, the material is waterproof, but the cubes have a mesh on top, so in general, the cubes are not waterproof.
To be honest, the textile producer advises against machine washing. Despite this, we've successfully machine washed a complete set in both cold and warm water three times with no issues. Additionally, please refrain from using a dryer on these items!
Every packing cube has a thoughtfully placed solid zipper. It is convenient to unzip them down from the handle.
Despite the ultra-lightweight of the material, the strong double stitching will take your worry away!
You can fold them conveniently and put all packing cubes including the laundry bag into the Small-size cube which can easily be tucked away in the corner of your wardrobe.
