Hi ladies, I recently upgraded from Ameda Purely Yours to speCtra S2 and in search of a new bag to carry it to work. Most bags on Amazon are expensive but I do understand quality over quantity. I'm just wondering what bags you all are using, how much, from where & if you would like recommend it.

Thank you in advance ♥️
