I feel like many fly sheets are soft and mosquitoes bite through. Anyone used a fly sheet that is also effective for mosquitoes?

This is my first year with fly sheets & I have bought  a lot of the cheaper ones to try out & was very dissapointed until I ran across Schneiders Mosquito Mesh sheet.  It keeps flys, mosquitos, deer & the large horse flys from getting to her. It's a bit more $ than the others...but it's worth it.

Thank you!

What about fly masks?  Mine are out in pasture & we live by a dairy the flys are horrible on their faces.  Was wondering can you leave them on at night in pasture or best to take them off at night & put back on during day?
