The best backpack for any digital nomad cannot be predicted freely. It depends upon the DM and his/her traveling area. Moreover, it depends upon so many factors like the gear to be carried, route, whether traveling solo or group etc.
Always, while choosing a backpack as a DM.choose a lightweight backpack. Don't overburden with a heavy load on your back. The backpack market has got plenty of choices for selecting one good backpack. While choosing a backpack for DM consider the gear organization, features, durability, brand, previous customer reviews, and the cost. Don't think always a costly one will bring all good features. There are several good backpacks available with a lot of features at an affordable cost.
Spending a few minutes online before making a purchasing decision will save your pocket and bring comfort.
