We have something to celebrate: Our Helium series with the classic quilted pattern is turning 10! This vest from our best-selling series is incredibly lightweight and easy to pack away. The wind- and water-repellent outer material with high-quality down filling in 90/10 quality makes this piece the ideal companion for your outdoor activities. The vest can be worn both as an outer layer and as an additional warmth layer under a shell jacket. Peak Performance exclusively uses sustainably sourced down with "Track My Down®" provenance certification. Made from PFC-free recycled polyamide.
