Must Have
In preparation for cooler weather, I wanted a slightly thicker than your typical running long sleeve and this fit the bill perfectly. It kept me warm during a 39 degree weather run without being hot. I wore a short sleeve underneath and it was a perfect layering combo. I am 160# 5’2” and a large was the perfect fit. It covered the tummy without it being too long and it’s not a slim fit like most women running tops are. Even with a short sleeve underneath, this top still room. This is a very comfortable top and worth every penny. Will end up buying another for rotation.
Why are most ‘athletic’ clothes made from plastic?
I like this shirt very much but polyester? So much running or hiking clothes are plastic, what gives?
Great shirt but weird fit
Found this shirt on the clearance rack in my local REI store. Loved the material and the color, however I could not tolerate the shortness of the sleeves with my thumbs in the thumbholes (my main purpose for the shirt), and I could not tolerate how tight it was in the front of my neck (I kept tugging at it). I am an average sized 5'6" frame, like I don't have exceptionally long. arms or neck or anything. Maybe this would better fit someone who is more petite.
Great running top
Recently bought this for trail running in cooler weather. Overall I really like this top. It was about 30 degrees on my run and I wore this top without any layers. It kept me warm without overheating. Only complaint is the neck line could be looser. If you are between sizes would recommend sizing up.
Great color - weird fit!
I loved the color of the blue. The material felt nice as well. However, the arms felt really short on me and I have 5'5'. The neckline also felt weird on my neck. I wanted to love it but I wound up returning it.
Great for cold runs!
Love the thumb holes, hand covers with fleece like lining, zipper pocket on side of the shirt. The fit is cozy but not skin tight. Loveeee this shirt for running in the cold weather so far.
LOVE
I LOVE this shirt. I am a huge fan of micro grid. I love the pocket, thumb hooks and hand covers. This is the perfect layer for cold runs. My new favorite.
great for cold runs
This is my new favorite for cold winter runs. Keeps me warm and dry. I also love the fold over mitten feature and my hands stay warm in 20 degree weather.
Fits great!
This is a perfect layering shirt that’s not too tight or clingy. I’m not too hot wearing this. Please make it in more colors. It is a great shirt!
OK
Haven't worn this yet but trying it on it is comfortable. When I washed it I noticed that the wrinkles that were in the front did not come out.
