Negative Pressure. Positive Work Ethic. — Xylem Hoodie

Negative pressure. Positive work ethic. A little tree science for the days that ask more of you.

A tree can look completely still while water is moving from its roots toward the canopy. The leaves set that movement in motion: as water evaporates, it creates tension that pulls water through the xylem. Cohesion helps the water molecules stay connected along the way. Quiet work, happening beneath the bark.

This hoodie gives that process the full-back treatment. Cream lettering and blue-and-ivory flowing lines carry the message, with xylem facts worked into the design. The official Knotty Intentions logo at the chest keeps the front simple and recognizable.

Pull it on for cool mornings, a walk beneath the canopy, or the well-earned part of the day when the gear is put away. For the tree people who appreciate what is happening under the surface.
