The key points

Water resistant


Developed in collaboration with numerous athletes, the Pulse 12 Ultra women’s trail running vest is specifically adapted to the female body type. It will bring you comfort and stability on all your outdoor outings (trail running, hiking, Nordic walking, cross-country skiing…). No more discomfort or rubbing!

Its 3D Coolmax technology located on the straps and the back panel, favouring thermoregulation, offers excellent breathability. Its robust 40D Ripstop fabric (10000mm waterproof) is a guarantee of quality and durability and will keep your belongings dry.

Organize your personal belongings and mandatory running gear easily with the many storage compartments.

If you run with poles, you’ll especially appreciate the Easy Fix Pole Control system or the expandable quick access pocket on the back of the running vest.

And if you’re a race number fanatic, the Pulse 12 Ultra trail bag is equipped with a clever magnetic race number holder. No more holes in your shirts!

The Pulse 12 is our best-seller and is recognised by many female runners for its quality and reliability.

This new trendy colour will go perfectly with the tee-shirt and the short skirt from the same collection!
