After trying three different brands, this is the first one that actually blocked the midges in our area. It’s not the most "luxurious" looking drape out there, but if you actually care about not getting bitten while you sleep, this is the one to get. Shipping was fast too.

Waaay too heavy. It clogged my pores and gave me tiny bumps all over my forehead. Definitely not for oily skin.
