On a mountain ultra you want gear designed by people who run long distances themselves. A vest that stays put, a jacket that fits over your pack. That's exactly why we carry Raidlight at Trail.NL.
The French brand makes running vests, rainwear and gear for long distances in the mountains. Many details are practical, like a jacket that fits over your vest or flasks you can grab without stopping.
For us, Raidlight is above all a brand by and for ultrarunners: well thought out, functional and made for the days when the weather turns against you.
