Brooks-Range Cirro collection of jackets, hoodies and pullovers use Primaloft One insulation. Synthetic insulation doesn’t get any warmer, or fluffier. Primaloft One acts like down for warmth, except it retains a good chunk of that warmth even if it gets wet. At only 60 grams per square meter, it's light too.
Even so, it stays dry with Pertex, a super fine denier nylon for the shell fabric. It's a good barrier to water, but it breathes too so it's not watertight. It also stops wind dead in its tracks. Though it feels smooth, it uses rip-stop nylon threads to prevent snags and tears.
The Cirro Jacket comes with a full-length zipper, a small, zippered stash pocket, elastic cuffs and an unbeatable price. Available in small, medium, large and extra-large sizes, in red, blue, or black colors.
