Witness × Marathon Mate
MADE TO BE SEEN
Marathon Mate started with two friends training for the 2026 Brighton Marathon. They wanted a running vest that was light, secure and, importantly, helped them stay visible when running on darker mornings and evenings.
So they made one.
Whether it’s an early morning run, a few miles in the evening or simply getting out there, Marathon Mate is made to help you be seen and support you.
