Nothing protects you from the harshness of the New Zealend elements like Swandri. The secret blends of wools and water repellent finishes have been used in these Swandri bush shirts for over 90 years. The combinations are used to keep you warm when you cool down, and cool when you heat up. And they keep on doing the job, season after season, with the natural toughness of wool in every single thread.
