Good Day Bag
I used a 5L See Dry Bag from SealLine for the few things I wanted easy access to on a river trap. It's helpful to be able to see through the bag to find what you're after quickly. With the 5 L size I could fit my extra layers (midweight fleece and lightweight fleece vest) and sunblock. I'd highly recommend the 5L or 10L size for this purpose. The bag seems well made (and kept my stuff dry) though I would not call it the most durable dry bag out there by any means. This bag fit the bill for my "day bag" needs perfectly, and at a reasonable price.
