Love this vest

This vest is so lightweight, but keeps you warm. Perfect for backpacking and hiking, as well as just for everyday use. Loved this color (Rosedawn)--sort of a peachy copper. It actually is a great contrast to so many other colors.

The perfect layer
7 years ago
Was looking for a layer with versatility and I found it in this vest. The 850 down is perfect with a LS underlayer and light wind/rain over. Going to use it for 546miles of the El Camino Santiago in Sept/Oct. The shiny light blue color I bought is a real eye catcher for traffic.
