Lumen 600 V3

This light is lightweight, comfortable and bright!, I used this in a 12 hour night race and could keep the brightness as high as I wanted (because the batteries are cheap and easy to change). It lit the trail well and allowed me to run at my pace (did not need to slow down for visibility).

This vest is AMAZING!! I’ve had many vests over the years but this one beats them all, hands down. I love the placement of pockets, materials used and the overall thought of design that will be long lasting and comfortable at the same time.

Nucleus Vest

Love the design with easy front bottle and phone access. I am short with short arms and love that it’s just an easy grab upfront and super easy to put back in place. Love the magnetic pickers for key fob and nutrition. Such an innovative design and UltrAspire nailed it.
