I'm new to the travel backpack world. I generally travel with a carry-on suitcase and may supplement it with a personal sized backpack. I've been wanting to get into more minimalist traveling and have been doing research into travel backpacks when I saw the post about the Mystery Box on my Facebook feed. Since it was a great deal, I took a chance and ordered the Transit Mystery Box. To my delight, I received the 35L backpack in Wasatch Green, exactly what I was hoping for. I have yet to travel with my new bag but if all the positive reviews I have read about it are accurate, I believe I will have a great experience with it.
