love it
Its a great color and it keeps me warm and its thin enough to go under other vests.
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.
Great!
Very comfortable and warm. Love the color and cut... easy to hike with and not too puffy for the warmth.
Gift to Daughter-in-Law
She loved it - just in time for cold weather. Her kids saw it and thought it was great.
Down fast
Love the color love the way it fits very functional
The perfect layer
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.
Nice extra bit of warmth
Attractive fit, warm, very lightweight. Perfect for a vest.
