I almost sweat perceptibly today. I was down to a think synthetic Arborwear shirt, Arborwear tech II pants, gloves, buff and helmet. Buff, muffs and a visor add a perceptible amount of heat. I'm ready to put my mesh screen on. It cuts the sun a bit.
I like buffs...covers the neck pretty well, and kept the moss at bay. I can hold my breath while cutting (sometimes stopping cutting for a couple breaths, then recommence breath-holding and cutting) so sawdust isn't so bad, unless the wind is going the wrong way. Very mossy maples today, in places inches thick.
