Pack Cubes fit perfectly in Carry-on Bag
"I purchased these to go with my Briggs and Riley Carry-on Bag. They are very expensive but fit perfectly. I'm not sure they need to have the compression zippers when the actual suitcase will compress but I do like that they are perfectly sized for the carry-on bag. Now Briggs and Riley needs to make some for their new compact spinner bag since the existing ones are sized quite right."
