Get dressed in THE IQONE

A THE IQONE thermoregulating T-shirt combines a base of wood-cellulose fibres with Outlast® PCM technology — a phase change material originally developed for NASA. The microcapsules take up excess heat when it gets warm and release it when it gets cool. They don't just heat or cool in one direction — they buffer the changes that keep coming through the day: car, air-conditioned office, outdoors, shop.

Composition: 56% Tencel™, 37% Outlast® viscose, 7% Lycra® — 93% fibres of natural origin (wood cellulose), no polyester. According to Outlast® data, PCM technology reduces sweating by up to 50% (measurement: C. Russ — INSIDE CLIMATE, Munich). Customers tell us the T-shirt doesn't pick up odour even after a full day.

Is it a thermoactive shirt?

Not quite. A thermoactive shirt, usually made of polyester, wicks away sweat that has already formed. A THE IQONE thermoregulating T-shirt reacts earlier — it takes up excess heat before you start to sweat. It works best where movement alternates with standing still: on the trail, out in the field and through a whole day in town. Full comparison.

How is it different from cotton?

Cotton absorbs moisture and dries slowly, so after a few hours it's wet across the back. Tencel™ with Outlast® viscose handles moisture next to the skin better, and PCM helps limit overheating.

Is it for women and men?

Yes. Sport comes in separate cuts: women's (fitted at the waist) and men's. Worker is unisex, and the headband and balaclava are one size. For her · For him.
