"Excellent, lightweight top! I tested this out on a day with 90% humidity… whew! Loved the lightweight feel and I never felt weighed down when the top got drenched in sweat the further I ran! Will most likely wear this for an upcoming 50k ultra race in September! Runs true to size."

Fastrock, my fave tee!
"I LOVE the purple FastRock tee! The fabric is lightweight and cooling so it drys fast and it’s so comfortable. I wish I could get this as a regular tee instead of a crop version so that it would pair better with my hydration vest. As a crop, I have to keep pulling it down. Otherwise, I love this shirt and it deserves 5-stars!"

Good not perfect. ;)
"It is cute, but a bit longer would be better. (but I have a long torso). It was not as cool as I had hoped. . . some under arm venting might help. All said I will wear it and I love your gear."

Not a trail runner but loving this for all running
"First, I was happy to see how thin and airy this fabric feels. I also love the fit and sleeve length. For reference, I’m 5’3” tall and 105 lbs. yet I often size up from XS to S because I don’t like constrictive fit. I’m happy to say that even in XS, this top feels very free while still looking very flattering, partly due to the cropped length. The sleeves cover my arm almost to the elbow which is what I was hoping for since that’s half an arm not to have to slather on sunscreen. Even though I’m not a trail runner, it looks and feels like a fabric that will not pill from vests or other outer layers. The design is just as striking in person as online, and in the neutral colorway that I chose, it looks great with every single pair or shorts I own."

Loving this tee for summer!
"Big fan of this tee - it’s lightweight, breathable, and has a boxy crop fit that doesn’t ride up under a vest! Sleeves are a nice length and material feels great when wet. rabbit nailed it with this tee!"

Best. Shirt. Ever.
"The fit and material are absolutely perfect. I will wait to go on a run until my laundry is done so I have this piece to wear!"
