Great Puffer!

Not very puffy puffy jacket
Size: XX-Large, Color: Denim Blue
At xxl the shoulders fit well and perhaps the first jacket where the sleeves came down to my wrists and not halfway to my elbows if I reached forward. Love the zipper. The zipper pull is at my right hand side. It is where i would use my right hand to engage and pull it closed. The zipper glides smoothly. The hood is voluminous. There is no string available to control the fit of the hood. As it us the hood is much too large. It makes the jacket look cheap and unfinished. The jacket would be immeasura bly better if the was a bit more fill in the body and a string pull in the face of the hood to bring the fit closer.

It's thin but it's good for cooler mornings and windy days
This jacket is not super thick or sherpa/fleece lined. But it's great for cooler temperatures, windy days, or staying warm while out on a boat. It's lightweight, cuts the wind and is great for layering. Folding it into the bag makes it ideal for travel and camping

Okay for the price
Size: XX-Large, Color: Denim Blue
The product was light and compact for packing for an Alaska cruise. It was also sufficiently warm and relatively rain resistant. But on the second day of wearing, the zipper blew out. I was able to fix for a short while, but in the end, I couldn’t use it.
