The Timbuk2 Grubstake Laptop Pack is a load-and-go pack. With only an internal laptop sleeve, and no external pockets, this pack is designed to be filled to the brim with whatever you wish. It’s perfect for trips to the grocery or loading with textbooks. The TPU exterior panel makes this pack almost waterproof. So now you don’t have to worry about those freak rainstorms ruining your goods. And the ergonomic straps actually fit your body, making this pack a delight to wear. But be careful, if you just throw your wallet in loosely, you might have to dig for that buried treasure.
