Had the pleasure of trying it last week after getting a newsletter email link from Abby's for free product. I tried Sabino Moisture Block, and it locked in all the moisture I need (my hair is dry so I left in some conditioner at the last step), and blocked out the moisture I didn't. It just rained a couple days ago and instead of having huge hair, my hair stayed smooth and shiny.  Yes I was under an umbrella, but still, just the humidity in the air would normally frizz me out. Here's the link to the newsletter where I found out about it. They have a free sample fill out thing so you can try it for yourself! A plus!
