Flyout Mock Neck Long Sleeve


Color: Ivory/White

A fresh new take on the beloved Mile One silhouette of the past. This is the perfect lightweight layer for a little extra warmth on crisp mornings or cool evenings. The collar is double-layered to give the neck more structure and support. Fun color blocking makes this long sleeve stand out from the rest. Once you're warmed up and ready to roll, shed the Flyout Mock Neck and tie it around your waist with ease.

It’s my go-to!

This has been my go-to shirt this winter!! The fabric is super soft, stretchy, and comfortable. It has a flattering fit that doesn’t cling. I love the green/red color way. I have the Mile One shirt in thicker fabrics from previous seasons, but I’m always reaching for this one. I prefer staying a little cool on runs. It’s perfect on its own for temps in the 40s-50s and would layer well over/under other pieces for wider temperature ranges. The collar is just the right weight to keep you warm without overheating. The sleeves are long enough to cover your hands for a little extra warmth at the start of a run, and they go over your elbows easily once you warm up (unlike shirts with thumbholes that are tighter at the wrist). The sleeves hold their original shape after being pushed up. It’s such a fantastic piece that I bought two! It’s sold out now but I hope to see it in more colors in the future.

A little flyout spice!

It's fun to have a new style in the flyout fabric! I love flyout so much and just look for an excuse to buy it. I've liked this style for the cooler weather running. It's nice to have the benefits of the flyout fabric in the body, but with a nice built in collar/gator piece.
