Poor Fit

"I wanted to love this tank, but the fit was off. My measurements are 5. 3ft, 135 pounds, 36C, and I ordered the medium. The overall fit was too big and the arm holes were huge and gaped out. I exchanged for a small and it fit better, but the length was too short and my stomach was exposed above my shorts. Returning again."

NEW FAVORITE SHIRT!

"So light & breathable! Wore it for a relay race on a ridiculously hot & humid weekend and I'm so stoked with how it held up! Now I just need more colors!"

— christina h. (5/5)

long run dream

"Where I live is extremely humid, and this tank did great on my long run. It stayed cool and did not cling through 28k. I will mention that I wore it under the osprey hydration pack, and the pack chewed up the fabric a bit. I don’t especially care because I’m going to continue wearing it under that hydration pack, so the snags will not be visible. Great shirt overall."

Material feels great

"I love this lightweight top. However, I wore with a backpack for a few hours, and the material started to wear and pile where the straps touched. I would still recommend, but don't wear with a running vest or backpack."
