Are tiny biting insects ruining your outdoor experience? Do midges, black flies, no-see-ums or sand-flies gravitate towards you, leaving you with itching welts once they've had their way with you? Consider upgrading your headnet to our ultra-fine mesh. More than four times finer than our existing mosquito mesh, even the smallest biting insects won't be able to squirm their way through, leaving you bite-free.
