I use it as a fishing net,water filter, to melt snow and of course bug protection
What do you use it for?

I don't have one yet, but with all those uses that I hadn't thought of (especially a fishing net), I'll be getting one

uh.. waterfilter? Thats one rough filter than, where do u use it for? Something made of cloth would perform so much beter.

headnet is a headnet and a little bag for me when i'm collecting things. Incase i need to keep them seperated from the things in m pockets.

If I filter water, I use a coffee filter and than add a micropur tab.
A headnet COULD be used for filtering. Mine has a very fine mesh, so it isn't rough.

I'm curious as to how efficient the headnet melts snow. The way I figure is you suspend it full of snow over a water container. Does this work better than filling a trashbag with snow. I would think the trash bag would work better as it traps moisture an heat.

One of the problems you have with melting snow is that the white stuff is such a good insulater that the container has been known to burn through. It's also very expensive in terms of fuel. One of the best ways to melt snow is to take a headnet, fill it with snow, hang up close to your fire.place a container underneath it. Snow melts. Drips into container. You drink or pour into insulated flask for later use.
