FERNFLOW x Dr. Bullock Hooded Windbreaker Mens
Designed to shield you against wind and light rain on trail rides and other adventures, this casual-fit jacket has a soft anti-wet cling fabric inside for next to skin comfort, plus an under-the-helmet hood for adaptable weather protection.
Dr. Bullock, a former high school principal, began spray painting bikes in 2019 and in just a few years became one of the most celebrated bike painters in the business. For this collab, he created a cohesive system of colors and shapes, that when cut and sewn, becomes a totally unique piece that will be yours and yours alone. Lightweight, comfortable and playful, it’s just the type of jacket Dr. Bullock loves wearing for outdoor adventures near his home in Portland, Oregon.
