This is where the Pen Wiwar story began. Yr Wyddfa was the subject of our first design and remains closely connected to the identity of the brand today.
Created by Pen Wiwar founder Dan, the artwork draws on Wales’ highest mountain and the landscape that helped inspire Pen Wiwar in the first place.
The Yr Wyddfa artwork features across the back, with the Pen Wiwar logo on the front.
