Flyout Wool Half Zip

FG icon


Half zips are an essential - beloved in the sport world. We love them even more when they're made from Flyout Wool, the superstar fabric that keeps you comfy in variable climates. It cools you when it's hot, and it warms you when it's cool. And now we bring it all together in a classic design that also gives you the convenience of heat release, and a bit more coverage at the neck. Even so, the design remains incredibly light and versatile... the perfect outerlayer for running, or under a mid-layer for fall and winter pursuits. Always soft, never scratchy, and washer-dryer friendly, this is wool reimagined.


• Front half zip
• Thumbholes
• Watch window
• 24.5" body length (size 4)


• Flyout Wool (polyester / wool)

Threading unraveled after wearing once.

I really wanted to love this top; the fit is good, and loved the color and design, but it seems poorly manufactured. I wore this once and the thumb holes threading immediately started unraveling. Seems like for the price it would be manufactured to hold up a bit longer…

Love this for winter running

Love this shirt for winter running! I have this in two colors (Mist and Ivory) and would love to have more if they had more colors available in my size. I find the shirt does run a bit loose so it isn't as warm as it could be, but I find it okay by itself for ~40 degree temperatures for easy runs (probably fine for ~25-30 degrees for racing), and with a Vigor vest, is fantastic for as cold as 20 degrees. I haven't encountered any pulling from the Mist shirt, which I wore for 1.5 winter seasons so far. Love how it dries off quickly when wet so that it isn't cold to wear - useful for runs where you'd socialize after the run.

Fabric snags

The size is great and the watch window is on point and in a good spot but the fabric is thin and sangs very easy.

Really like this!

I originally ordered this in the cream color in a 6 but it was too large and the color was not great on me, it was see through, and just blah. I exchanged it for the navy in a 4 and I love it! The differential striping at the neck and wrists is really cute and ithe half zip is nice to show your tank top underneath. The weight is perfect for a chilly day where you will be warming up quickly. It pairs well with black also. I got it on sale and so am very happy with it, but at full price I probably would have wanted something a little thicker.
