Yupster - Flash Strike

Nightflash Collection
Black by day. Flash by night.

A high-performance trail running collection built for runners who move through mountains, forests, and into the dark.
Ultra-light, quick-dry, and highly breathable—engineered to pair seamlessly with a hydration vest.

By day, it stays understated.
By night, reflective details ignite, keeping you visible when the trail disappears.

Quiet in daylight. Bright when it counts.
