The Breathedry waterproof smock is a lightweight, breathable, pullover jacket built with the arborist in mind. Extra-long back sheds water, and high collar with waterproof zipper and neck protector prevents water intrusion. An adjustable hood is big enough to fit over a helmet, and stows away in the color when not needed. Hood has a wired peak, a bungee volume adjuster draw cord, and a large hook & loop storm flap.
