And, I should add:
This is not, and shouldn't be considered to be, a mainstream headnet. It's less durable, it lets noseeums in, and it's expensive.
There are some folks that would be spending their money irresponsibly if they purchased this headnet. If you're choking on the price, then it's for good reason. Spend your money on other ways to lighten your kit. We're talking fractions of ounce here.
Look at the specs, and if it's worth it to you, fine, if not, great. If you want a cheaper option then I do recommend the OR Basic Headnet. It's very functional and offers a good value.
If you really need to pinch then you can find Coghlan's nets for $5 apiece, and they work well enough.
