I have a ShortyLove backpack pictured here. It slips terribly (slippery fabric) and pulls my suitcase to topple everything over. I have strapped it on to the extended 20” carry-on handle.

I have reduced the weight in the backpack so that it’s not top heavy. 

The product description says it’s a water resistant nylon Twill. I love it and it’s beautiful quality but I struggled with a terribly last week in Italy.

Does you have any suggestions on how to either secure it better or add some sort of grip so that it’s not so slick.

I’ve just written to the company but thought I would ask you as well. Thanks!
