The shit eats through plastic and titanium for christs sake. Deet today equals horrible screaming death later. Just cover yourself with long sleeve shirts and the like. A turtle neck cotton shirt will work well as well. No you dont get much hotter than anyone else out there.
Sunglasses are useful.
But only as usefull as the person using them. If your partner doesnt like them he will steal them for himself or throw them in the bush and you will never see them again. Your eyes absorb uv radiation as well. Learn on a staff if you think you will be planting for a long time. You will fuck your hand up if you dont.
