Primaloft® SB
The lightest and most compactible synthetic insulation on the market.
Primaloft® is a high-loft, lightweight insulation that is unsurpassed in its ability to keep you warm and dry. It combines softness and compressibility with superior insulating qualities for even the harshest conditions. Primaloft insulation is proven to be warmer wet or dry, and absorbs less water than its competitors.
When compared to down, Primaloft has similar softness and comfort, but not the technical limitations with regard to moisture.

Good hat. Blocks the wind and keeps you warm close to freezing. You'll need something warmer for freezing or below, but it will still keep you warm. I'm very sensitive to the cold, so it might be more satisfactory for other people with a better tolerance. One slight negative, if you have a big head- like me- it is a very snug fit, though it will break in. Overall a good hat with a good style that will serve you well in most temperatures-except for the very cold. The packability of it is a really nice plus too. Fits in your pocket.
