Firstly, I have a few different drawstring bags that I use for various reasons.  But this Adidas Alliance II is certainly one of the best for your money!

It's very practical for a variety of uses, but I primarily use it for a work bag and as a daily carry-all.  The main compartment can easily house your larger items (I have my Herschel network bag to keep smaller items separated, my iPad, notebook etc), while the front zipper compartment is great for small items (like your car keys/fobs, wallet/cash, work ID badge, etc), & the 2 mesh pockets on both sides of the bag actually go much deeper than expected (making them ideal for water/drink bottles, I also throw in my sunglasses/cases without worry of them falling out).

Don't hesitate if you need a great drawstring bag, you'll be very happy with this Adidas Alliance II.
