2 Rackets Tennis Racket Cover Padded Tennis Racket Bag with Handle and Adjustable Shoulder Strap

I don't trust my racquets in checked baggage. I've seen a lot of people just use a backpack style bag and had no issues with the grip sticking out. Personally I bought one of these and carried it on the flight with me; had no issues and it fit under the seat well. Surprisingly, each racquet pocket had good inner slots that I stuffed with extra grips and string. The outer zipper has way more space than expected, and was great for carrying phone, charger, passport, headphones, a book, and whatever else you might want on a flight. Works as an alternative to bring to the court when I don't want my large duffel, as the outer pocket can fit a small towel, a hat, etc.
