Recommend a waterproof diaper bag

grimesk12

So I have a really nice diaper bag that my mom made but it's not waterproof. I'm looking for recommendations for a waterproof diaper bag that doesn't scream "I have a baby". I'd like one that's not too small or too big. Oh and the more affordable the better (like $80 or less).The worst part is I have to shop online since I live in bfe and have no stores around to shop at.

Thanks in advance for your suggestions!
