Hehe... Especially weird because most of these bags are masculine in French... with a few exceptions!
Le Speedy
L'Alma (masc)
Le Keepall
Le Twist
Le Noé
Le Neverfull
Le Montaigne
Le Voltaire
This is because we implicitly refer to "le sac Speedy", sac being a masculine noun.
On the other hand, everything that's a pochette or a suitcase would be referred to with a feminine article:
La pochette Métis
La pochette Clés
La valise Pégase
The particulars of Latin languages 😃😃😃
