This year (so far) has been conducive to all those biting bugs we all love to hate.
When I head out, day or night, I prefer to wear long sleeves and sweats (coated with a dose of bug spray) and a face covering.
Serves double duty, as stops the bugs and prevents sunburn.
Heck, although I haven't done so in quite some time, I used to fish a bridge in Duxbury MA during the summer with temps in the 80's wearing jeans, long sleeve shirt, a windbreaker and neoprene gloves.
Sweat a lot but didn't have to do the "mosquito slap-dance" and could concentrate on fishing.
