They trust us

The specific adaptation of the OVERSTIM.s range accompanied the best performances and allowed the brand to be represented more than ten times on a podium of the UTMB® since 2011 (François d'Haene, Nathalie Mauclair, Sebastien Chaigneau, Ludovic Pommeret, or Yeray Duran Lopez)

François d'Haene, 3 times winner:

"During my training sessions and my ultra trails, it is essential for me to hydrate myself properly and to supplement my energy expenses.

Today, my collaboration with OVERSTIM.s motivates me for several reasons: the diversity of products, the attention paid to their origin and of course the fact that production is French and organic!

I also appreciate to find a development team ready to work on product development and innovation. "
