Very convenient to carry anywhere! ✅ Adjustable back band The back band connected to the pillow has an adjustable circumference range of 34CM to 45.5CM. ✅ Dual air valve Our product has been improved. In addition to the existing air valve, we've added a protective cover to achieve dual protection, effectively extending the service life. $$2980
