Mesh density varies across products, typically ranging from about 600 holes per square inch up to 1,600 holes per square inch in available nets and bug jackets.
Some heavy-duty mesh tarps are breathable yet block a substantial amount of light—around 70%—and many are treated for UV resistance. Check the specific product details for the exact UV treatment and rating.
Mesh tarps commonly include secure tie-down points such as brass grommets spaced about every 2–3 feet. Some rainflys also use corner hook attachments to fasten to a screen tent.
Screened tarps often use heavy-duty polyethylene mesh. Rainfly covers are typically made from poly-oxford or poly-oxford-style fabric, and insect nets usually use polyester mesh (for example, 15-denier 100% polyester).
Rainfly-style covers are described as water-resistant and commonly made from poly-oxford fabric with taped seams. Mesh tarps are noted as water-resistant and tear-resistant, and some are treated for UV resistance.
