My newest , best. Favorite, Safest backpack ever

A little clumsy at first but easily acclimated. A few tugs here and there and this is durable, safe, armored lockable and stylish. I hesitated before purchase and so glad I did.

A MUST

This is nothing special yet everything special. Amazing sense of security, light weight and oddly comfortable. Absolutely the best gift idea for ANYONE that travels and for anyone that doesn’t. Would love to see a cross body.
