I could use some advice on which Messenger Bag to get ...

I already have one Messenger Bag, about 12 inches long (too short!), 8 inches high, and about 4 inches thick.

I need a Messenger Bag much larger ... I've been looking at over 100 different Messenger Bags, and found these two that look interesting:

I ride my Surly Long Haul Trucker everywhere ... Work, Shopping/Errands, Church .... I need to carry several books at times, food for the day (I have Hypoglycemia really bad!!!), medicines, ID, Keys, several water bottles, scarf, stocking cap, gloves, and maybe a compact poncho. Also might carry my tablet, either 8-inch or 10-inch, if space and safe pocket.

I'm looking for something that has two water bottle pockets, one on each end. I would prefer a Flap that fits over the bag, so if the zipper breaks, I can at least still cover the bag with the flap. At least one out pocket would be nice for easy access.

Since I will be carrying food and books, would be nice to have separate pockets, so if the food spills, the books will not get damaged.

Is anyone familiar with either of the Messenger Bags I am looking at, or could suggest something else? I'm looking at spending around $100 or less ....

Thanks for reading. I really need to get something soon .....
