| 3D BIONIC SPHERE® | The award-winning 3D Bionic Sphere® system stops unpleasant moisture, overheating during intense activity, and prevents cooling during rest and recovery phases. |
| MERINO WOOL | The comfort and performance of merino sheep wool are exceptional. Soft and supple, this wool is an excellent thermal insulator that ideally regulates body temperature both in winter and summer. It can absorb a third of its weight in the form of water vapour, and its heat release prevents the feeling of chill. Even when wet, the garment remains warm. Wool fibres are naturally resistant to mechanical wear, stain little, and are antibacterial, significantly reducing unpleasant odours as well as washing frequency. Like all natural materials, merino wool is biodegradable. |
