Hey, the title says it all.  I have tried everything but I just can't do it.  The way the backpack is, I didn't like my character at the time, but I don't want to remove the skin when I'm not in the game.  So if anyone knows, please let me know.  If not, please do Tencent, make it so that we can wear helmets and backpack skins, don't force us to show off when we're in the lobby.

According to what I understand, you don't want to wear your helmet / backpack in the lobby, but it protects you from using that skin in the game.  What am I doing, I chose my helmet skin in the lobby, then go to the Hats section and put one on.  This removes the helmet.  Now I also remove the cap to press it again.  This way you will have helmet skin in the game
