| Merino Wool | The comfort and performance of merino wool is simply outstanding. It is soft and very flexible. It provides excellent thermal insulation and body temperature regulation in both winter and summer. It can absorb a third of its weight in the form of water vapour and its heat supply prevents the feeling of chill so that the top remains warm even when wet. The wool fibres are naturally resistant to the effects of movement, do not show dirt and are anti-bacterial, which greatly reduces odours and the need for washing. Like all natural materials, merino wool is biodegradable |
| ZoneKnit™ | Zoned construction technology helps regulate your body temperature during high-intensity activities. |
