vvnpo,
Frankly I have not seen the new air one; No way to make comparison. I just remember that I dont really need the active one; However, 如果新款的肶位有更多空間就更好了!因為這個揹帯可承受到差不多30lbs的bb,換句話說它可以由三個月開始用到接近學行都用得著,但bb大過後,如果她有一對'肥patpat+肥肶肶';可能就會有點緊,這是我用後唯一的concern,不過我亦曾問過一些媽咪使用其他的揹帯的comment,好多都話用咗一兩個月就無用,因為用起上來唔方便;好像是個扣唔夠穩陣,有啲又好煩要伸手去背脊先扣到,有啲二百幾蚊條嘅將bb打橫咁'擺'係面前'郎郎'吓;用咗先覺得好牙煙!
