G'day Anne,

It does have an odor but it's difficult to say if it's strong or not.
I'm personally not a fan of Permethrin treated stuff, as I'm sensitive to it, however, most people don't have any issues.
There certainly hasn't been any complaints or negative feedback from customers, so you should be ok.

G'day Andy,

Generally, the Permethrin treatment will last for about 12 months, or up to 30 washes. 

They are roughly 50cm from the seam around the top to the elastic at the base, Alexa. Length, when worn, will vary depending on what you are putting it over, and tightening the bottom will shorten the length too.

I hope that helps.

G'day Sarah,

There is just the one open end that has a drawcord to secure around your neck. The top is stitched up so you can pop it over a hat or your head.

G'day Kathy,

I don't have a bunnings hat here to try this but I think the headnet will be a little too small to fit over one of these.

G'day David,

It's hard to give an accurate answer as no-see-um mesh is a trademarked type of mesh. What we do know Mosquito Headnet Permethrine not only has an ultra-fine mesh, the mesh has permethrin embedded into it, which will keep the mozzies at bay. 

G'day Brent,

The manufacturer doesn't specify any safety precautions in regards to the permethrin for children however it might be worth consulting a medical professional for clarification. It's also worth checking out the Royal Children's Hospital website, which, among other things mentions Permethrin treated clothing for children.

G'day Pam,

Yes, the Mosquito Headnet Permethrine Treated comes in a small lightweight nylon sack.

G'day Ann,

I've just grabbed a Sea to Summit Mosquito Headnet to measure for you. The circumference of the hole at the bottom is about 100cm and it's about 37cm from top to bottom when laying flat.
