Urgh this is really though question

I use B35 DE alot when my kids are small / babies .. Coz it was also for the diaper bag and others. I didnt use other bag for 2 years straight since its so carefree ..But now the B35 is more for travelling since it can fits the whole house

.. While B25 (in Mono) fits better with my daily life now and Im more carefull with it than the DE..If I can choose , I would choose B25 or B30 in DE if you want to use it for daily life without thinking so much
Did you go to Budapest already? How did it go ?
