Introducing the rabbit Clubhouse Series, a curated hospitality experience popping up at three of the most iconic races in the world: Chamonix, Chicago, and New York City. This is race week done the rabbit way.
The Trail Tour is back! We’re teaming up with 32 incredible races across the country. Race, earn gear, and join a community of trail runners nationwide.
Meet the Chase Team, a group of 11 athletes balancing big OTQ dreams with real life. Some are chasing their first-ever spot on the Trials starting line, while others are returning to the pursuit after childbirth.
Layer one matters most. But will any flatter and fit like our new thermal top? Lightweight grid fleece performs as a breathable base or solo layer. Flatlock seams reduce chafing for long-lasting comfort.

Most orders are shipped within 3-4 business days; orders over $125 ship for free within the U.S. International shipping is available for most countries.
Layer One is a lightweight grid fleece thermal top designed for cold weather running. It is made from a blend of 67% recycled polyester, 27% polyester, and 6% spandex, offering warmth, stretch, and quick-drying properties. Customers appreciate its tailored fit and flatlock seams for reduced chafing and long-lasting comfort.
"I would size up because it's a tailored fit, just wish there was a relaxed fit option for us self conscious gals." —

Layer one
"This is the softest running shirt I own. I wear it in cooler weather often because it is very comfortable and warm. I really love the pink color it’s very pretty! The arm length is perfect, though I wish it were a little bit more cropped at the bottom."

Do Anything Layer!
"I am so impressed by the Layer One! I love the durability and warmth it provides, while also being lightweight. The best feature is the loop on the outside of the shirt (top back) for easy drying/hanging up. So simple and so helpful! Will be adding more to my collection!"

Abrasive fabric for highly sensitive persons
"If you are a highly sensitive person you will not like this fabric. The shirt is well made but I wanted to share this on here because I purchased this because one of the reviewers said the material is soft. That person may have thought so but if you are someone who routinely removes tags this isn't soft at all. The EZ tees are soft! They are the most wonderful shirts and I live in them, but this did not work for me."

Really good
"The Layer One is good base layer, maybe slightly warmer than the EZ long sleeve. This shirt fits like the original EZ long sleeve which I LOVED; if you like the new “relaxed” EZ LS fit, maybe size up in this? For reference, I am 5’4” 107# and got this in XS."

This has quickly become my
"This has quickly become my favorite go-to shirt. It's comfortable, feels great on, and love the ballet pink color! It's a perfect fit and I will be buying this in other colors! It's a great base layer or everyday top and the sleeve length is perfect!"

Lightweight and warm
"This shirt is perfect for the cooler weather it is lightweight but keeps you incredibly warm. Great worn alone or with a light jacket over."
