My perfect travel bag

I hesitated between a backpack and a suitcase a long time. After going over all possible Website about montain stuff i buy this one :

Like volkswagen and so many German brand I probably speak of the superiority of the German quality. Congratulations and thank you Deuter ! Then I would like to say thank to Le Vieux Campeur seller's for his patience because I really tried every bag in all the store. Every time i put 20 kilogrammes in each bag and i walk alone through the store during several minutes. After approximately 10 bag tried, i choose this one, and i'm glad to have it.
