| What it is | Breathable, moisture-moving active fabric |
| Focus | Sweat management & temp regulation |
| Not | A fully waterproof shell |
| Used in | Active wind shells, base/mid layers |
Pertex Equilibrium is a family of lightweight, breathable fabrics engineered to move moisture and manage temperature during high-output activity, rather than to be fully waterproof. Often using a dual-surface construction that pushes sweat away from the skin and spreads it to dry fast, it’s used in active wind shells, base and mid layers, and breathable insulation liners.
For working hard
A breathable Pertex family focused on wicking and breathability, not waterproofing.
Frequently asked questions
What is Pertex Equilibrium?
Pertex Equilibrium is a range of lightweight, breathable fabrics built to regulate temperature and move moisture during aerobic activity. Instead of maximizing waterproofing, it focuses on pushing sweat away from the skin and spreading it across the outer surface so it evaporates quickly, keeping active users comfortable.
How does Equilibrium manage moisture?
Many Equilibrium fabrics use a dual-surface or differential construction: the inner face moves sweat away from your skin while the outer face spreads it out to dry rapidly. This 'push-pull' effect, plus high breathability, helps prevent the clammy chill that comes from sweat building up during hard effort.
Is Pertex Equilibrium waterproof?
No — it's designed as a breathable, moisture-managing, often wind- and weather-resistant fabric, not a waterproof membrane. It's best for high-output use where breathability matters most; for sustained rain you'd want a waterproof fabric like Pertex Shield or a Gore-Tex membrane.
