The tween ones are bit more expensive but its worth it for my daughter to feel better about this time in her life. My 15 yr old loves the Always Infinity because they absorb well, but are thinner /more comfortable. If it makes my daughters more comfortable, I don't mind buying them the more pricey ones compared to the store brands. My 11 yr old loves the Kotex Tween colors, size and the little booklet that reassured her its okay. Make sure it says for Tweens on the box. Happy we could help.
