The Big Joe has been in the KAVU lineup for a decade, and there’s a reason it keeps coming back. The 6oz certified organic cotton flannel hits a useful middle ground — warm enough for cooler days without turning into a heavyweight overshirt. A herringbone weave adds subtle texture, while the casual fit and bias-cut back yoke keep it comfortable through the shoulders. This season, the longtime favorite gets an upgrade to 100% certified organic cotton. Same Big Joe. Better fabric story.
