Sea to Summit Nano Mosquito Pyramid Net Shelter

The Sea to Summit Nano Mosquito Pyramid Net Shelter is a single-hang-point pyramid net designed to protect one or two sleepers from mosquitoes and most flying insects in warm-weather and tropical conditions. Woven from 15-denier nylon mesh at 500 holes per square inch, it weighs as little as 90 g and packs to the size of a fist. The shelter is available in Single and Double sizes.

Asymmetric Shape Puts Space Where You Need It

On a standard pyramid net, the apex sits at the center, which means the tallest point is directly above your midsection, not your head. The Nano Mosquito Pyramid Net Shelter shifts the apex toward the head end, so the mesh clears your face and shoulders with room to spare. That extra headroom reduces the claustrophobic feeling of mesh pressed close to your face and lowers the chance of skin contact with the net during the night, the kind of contact that can allow mosquitoes to bite through the fabric.

Secure Base, No Zipper Required

An elasticized hem runs the full perimeter of the shelter's base. Tucking it under a sleeping mat or mattress seals the gap at ground level without stakes, clips, or additional hardware. Entry and exit are through the side: lift the hem, slide in or out, then tuck it back under. The absence of a zippered door removes a common failure point and keeps the packed weight low. Color-coded corner tapes and a single suspension cord make pitching straightforward even in low light.

Ultralight Mesh That Breathes

The 15-denier Ultra-Vis nylon mesh uses a hexagonal weave at 500 holes per square inch (80 holes per cm²). That density stops mosquitoes and most other flying insects while maintaining airflow, a meaningful consideration when sleeping in humid, still air. The mesh is black, which improves outward visibility so the net does not feel like a visual barrier between you and your surroundings. Both the net and the included stuff sack are 100% nylon. The shelter can be treated with spray-on or wash-in permethrin without harming the material.

Specifications

Who This Is For and Isn't

The Nano Mosquito Pyramid Net Shelter suits solo travelers and couples sleeping in locations with a single overhead anchor point (a ceiling hook in a hostel, guesthouse, or hotel room, or a ridgeline or branch in camp) who need lightweight mosquito protection without carrying poles or a freestanding frame. It works over a sleeping mat, cot, or mattress in warm-weather and tropical environments where mosquitoes and similar flying insects are the primary concern.

This shelter does not protect against no-see-ums, sandflies, or midges: at 500 holes per square inch, the mesh is not fine enough to block insects that require 2,000 holes per square inch or more. It does not have a zippered door, a built-in frame, or ground stakes, and it cannot be pitched freestanding. It is not designed to hang from a tarp; the geometry and required ceiling height make that impractical.

Common Questions

Does the Nano Mosquito Pyramid Net Shelter protect against no-see-ums, sandflies, or midges?

No. The Nano Mosquito Pyramid Net Shelter uses a 500-hole-per-square-inch mesh, which stops mosquitoes and most flying insects but is not fine enough to block no-see-ums, sandflies, or midges. Blocking those insects requires a mesh of at least 2,000 holes per square inch, which would also reduce airflow significantly.

What do I need overhead to hang this shelter?

The Nano Mosquito Pyramid Net Shelter requires a single overhead anchor point (a ceiling hook, a structural beam, a tree branch, or a ridgeline) directly above the sleeping position. It is designed primarily for use in rooms with ceiling hooks. It does not have poles or a frame and cannot be pitched freestanding.

How do I get in and out without a zippered door?

The Nano Mosquito Pyramid Net Shelter uses an elasticized hem rather than a zipper. To enter or exit, lift one side of the hem, slide in or out, then tuck the hem back under the sleeping mat or mattress. This seals the base against insects and removes a zipper as a potential failure point.

Can the shelter be treated with permethrin for added protection?

Yes. Both spray-on and wash-in permethrin treatments are compatible with the Nano Mosquito Pyramid Net Shelter's nylon mesh and will not damage the material. Permethrin treatment can add a layer of protection beyond the physical barrier of the mesh.

What is the difference between the Single and Double sizes?

The Single Nano Mosquito Pyramid Net Shelter measures 221 × 122 × 107 cm (87 × 48 × 42 in) and weighs 90 g. The Double measures 240 × 170 × 130 cm (94 × 67 × 51 in), weighs 155 g, and includes a 22-inch aluminum spreader pole (packs to 6 inches) to help maintain the shelter's shape over a wider sleeping area.
