Those Akito suits are kinda weird. They have a removable waterproof lining which goes on the inside. That mean the suit gets drenched anyway, which doesn't make much sense to me.
I have one of these Bering rain suits. It keeps the rain out nicely and is pretty visible in shitty weather. It's pretty big though, when packed tightly it's about the size of a small-ish sleeping bag.
