Sea to Summit Ultra-Fine Mesh Mosquito Head Net

The Sea to Summit Ultra-Fine Mesh Mosquito Head Net is a 23 g head net built for backpackers, campers, and overlanders traveling through areas with heavy insect pressure. Its 310-hole/cm² (2,000 holes/in²) hexagonal nylon mesh blocks no-see-ums, sandflies, and midges (insects fine enough to pass through standard head nets), while black mesh coloring preserves forward visibility. One size fits all via an elasticized drawcord closure.

Stops the Insects Standard Nets Miss

Most head nets use a coarser mesh that keeps out mosquitoes but lets through the smallest biting insects: no-see-ums, sandflies, and midges. The Ultra-Fine Mesh Mosquito Head Net uses a custom 310-hole/cm² hexagonal weave specifically sized to block these smaller insects. For anyone camping or traveling in latitudes where these species are common, that finer mesh is the difference between a tolerable evening and a miserable one.

Ultralight and Always in the Pack

At 23 g (0.8 oz), the Ultra-Fine Mesh Mosquito Head Net weighs approximately 50% less than Sea to Summit's standard Mosquito Head Net. At that weight, it costs nothing meaningful to carry on every trip and comes out only when needed. The net packs into its included stuff sack, which protects the fine mesh from snags and keeps it organized alongside other small camp items.

Permethrin-Compatible for Layered Protection

The Ultra-Fine Mesh Mosquito Head Net can be treated with permethrin spray without damaging the mesh, drawcord, or barrel lock closure. Permethrin treatment adds a chemical insect-repellent layer on top of the physical barrier the mesh provides, which is useful in high-density insect environments or when extended wear is expected. The mesh works as a barrier on its own; permethrin treatment is optional.

Specifications

Who This Is For and Isn't

The Ultra-Fine Mesh Mosquito Head Net suits backpackers, thru-hikers, car campers, and overlanders heading into areas with heavy populations of no-see-ums, sandflies, midges, or mosquitoes. Its universal drawcord fit works over most hats and caps, which also provide the face clearance the net needs to keep mesh off skin.

This head net does not include a stiffener ring; buyers who want structured face clearance without wearing a hat underneath will need a different net. It is sized for one universal fit and is not available in children's sizing.

Common Questions

Does the Ultra-Fine Mesh Mosquito Head Net block no-see-ums and sandflies?

Yes. The Ultra-Fine Mesh Mosquito Head Net uses a 310-hole/cm² (2,000 holes/in²) hexagonal mesh specifically sized to stop no-see-ums, sandflies, and midges: insects small enough to pass through the coarser mesh used in standard head nets.

Does it have a stiffener ring to hold the mesh away from my face?

No. The Ultra-Fine Mesh Mosquito Head Net does not include a stiffener ring. Wearing it over a brimmed hat creates the clearance needed to keep the mesh off skin. Omitting the ring is what allows the net to pack down to 23 g.

Can I treat this head net with permethrin spray?

Yes. The mesh, drawcord, and barrel lock closure of the Ultra-Fine Mesh Mosquito Head Net are all compatible with permethrin spray treatment and will not be damaged by it. Permethrin adds a chemical repellent layer on top of the physical mesh barrier.

What does the head net weigh, and how does it pack?

The Ultra-Fine Mesh Mosquito Head Net weighs 23 g (0.8 oz) and packs into an included stuff sack. The stuff sack protects the fine mesh from snags during storage and keeps the net easy to locate in a pack or kit bag.
