The Women's Sleeveless Cycling Base Layer is a lightweight, breathable mesh base layer cut for women's proportions to sit smooth under any jersey, in every season. Finestra™ mesh moves air constantly and pulls sweat off the skin out to the jersey, keeping you dry on hot climbs and warmer on cold descents. A sleeveless women's cut layers cleanly under short and long-sleeve jerseys with no lines under a race-fit jersey, and flatlock seams sit flat with no chafing or ride-up. Cut and sewn in the USA from Italian fabric, this women's cycling base layer is the foundation that makes the rest of your kit work, from spring through winter.

Best For

Recovery Training Hard Efforts Race

Versatile enough for everyday training rides, built to perform when the effort peaks. The Ritual Base Layer works hardest when you do.

Breathability

Low Moderate High

Fenestra's™ golf ball dimple structure creates continuous airflow channels against the skin, engineered to release heat before it builds, even at race pace.

Climate

Cool Mild Warm Hot

Built for warm and hot conditions. Fenestra ventilates aggressively to keep core temperature in check when the sun and the effort both bear down.

Fit

Relaxed Regular Race

A close, compressive fit shaped for a woman's proportions that layers cleanly under any cycling jersey without bunching, rolling, or adding bulk.

Air Where You Need It Most

Fenestra™ Construction

Fenestra is our warp-knit stretch fabric with a golf ball dimple structure, engineered to create aerodynamic airflow channels against the skin. It moves air continuously, releases heat before it builds, and keeps you cooler on hard efforts and long summer rides.

Sleeveless Freedom

The sleeveless cut keeps your shoulders fully unrestricted, no bunching under jersey sleeves, no restriction through the pedal stroke. Clean fit, clean feel, nothing in the way.

Fast Moisture Management

Fenestra™ wicks sweat away from the skin and dries fast. It doesn't hold moisture, it moves it. So even when the effort is high and the temperature follows, you stay dry and comfortable.

Built to Layer

Close-fitting and low-drag, shaped for a woman's proportions, the Ritual Base Layer sits flat under any cycling jersey without adding bulk or shifting position. It works with your kit, not against it.

frequently asked question

Why wear a base layer in hot weather?

A base layer isn't just for cold, the right one actively improves comfort in heat. Fenestra™ keeps air moving against the skin, wicks moisture faster than jersey fabric alone, and creates a microclimate that helps regulate your temperature during hard efforts.
What fabric is the Ritual Base Layer made from?

It's constructed from Fenestra™, our warp-knit stretch fabric with a golf ball dimple structure (82% Polyester, 18% Elastane, 180 g/m2). Four-way stretch, UV protection, and engineered to move air aerodynamically.
Will it fit under my cycling jersey without bunching?

Yes. The Ritual Base Layer is cut close and low-drag, it sits flat under any jersey without rolling, bunching, or adding noticeable bulk. This product is designed to do just this.
How does the fit run?

It's a close, compressive fit, shaped for a woman's proportions and designed to layer cleanly.
How do I care for it?

Machine wash cold, gentle cycle. No fabric softener, it reduces the fabric's moisture-wicking and breathability performance over time. Hang dry only.
