Made with the same super-soft, buttery fabric as our Circuit Crop Tank, but with a bit more coverage, this lightweight short-sleeve wicks moisture and provides odor control for everyday wear.
Made from ultra-soft synthetic fabric that feels great next to the skin, you won’t want to take it off when you’re back from the crag - and you won’t have to since the Circuit Tank has built-in odor control and moisture-wicking properties.

"Nice material. I ordered a large to accommodate my large chest, but this top was too big. Still, the material and cut are really nice so I'll reorder in a medium. It's a more relaxed fit, so order your usual size or size down if you are unsure."
"True to size, perfect for hot weather"
