Reviews

Too tight across upper back

"I followed the size chart & ordered a Small. I wear that base layer top size in Craft but this is uncomfortably tight between /across upper shoulder blades especially in biking position. Material is very thin & garment is long. I’m 5’5 & athletic, 67 yrs old. Will be returning. Too bad- color is lovely."

— Mary F. (4/5)

Form-fitting Baselayer

"This form-fitting shirt works great under a jersey. Once arranged, it doesn’t shift, yet it moves with your body. And the Lilac color is gorgeous."

— Susan W. (5/5)

Questions & Answers

The Pro Mesh Sleeveless Baselayer is for women riding in warm weather who want moisture management as their first priority under a jersey. Built around Italian fit and a 3D mesh fabric, it's engineered purely to move sweat away from the skin and keep airflow high. If most of your riding happens in heat and you want a skin-tight layer that disappears under your jersey rather than adding warmth, this is the baselayer built for exactly that job.

No — the Pro Mesh Sleeveless Baselayer is a moisture-management layer rather than a warmth layer. Its 3D mesh construction is designed for excellent moisture management, not for warmth retention. If temperatures drop enough that you need insulation under your jersey, consider the Active Comfort Baselayer for mild conditions or the Flow LS Baselayer Top when you want light warmth plus sleeve coverage. The Pro Mesh earns its place when sweat management, not warmth, is your concern.

The 3D mesh fabric in the Pro Mesh Sleeveless Baselayer is engineered to maximize airflow and moisture transport. The open structure pulls sweat off your skin and lets it evaporate, so you stay drier and cooler under your jersey on hot rides. For women cyclists, this means less clinging and overheating during warm-weather riding. It's one of the most sophisticated moisture-transport layers Terry offers for warm conditions, built specifically for wicking rather than insulation or warmth.

It depends on how you plan to wear it. The Pro Mesh Sleeveless Baselayer has an athletic fit and is intended to be worn skin-tight under a jersey, so stay with your usual size if that's your goal. If instead you want to wear it as a standalone lightweight indoor or outdoor mesh top, order up a size for a looser fit. Both uses work — the sizing choice simply follows whether you want an under-jersey layer or a standalone top.

The Pro Mesh Sleeveless Baselayer has a waist hem designed to stay flat under shorts, so it tucks in smoothly without creating a visible ridge. Combined with its close, athletic cut and 23-inch center back length, the baselayer keeps a low profile and disappears under both your shorts and jersey. For riders who want a first layer they don't notice and that doesn't interfere with the rest of their kit, this flat-hem design matters on every ride.

Yes. While the Pro Mesh Sleeveless Baselayer is built to be worn skin-tight under a jersey, you can order up a size and wear it as a lightweight standalone mesh top, indoors or outdoors. The same 3D mesh that manages moisture under a jersey makes it breathable as a top layer in warm conditions. The only decision is sizing: stay true to size for an under-jersey layer, or size up for a looser standalone fit.

The Pro Mesh Sleeveless Baselayer is sleeveless by design, with 3D mesh fabric for excellent moisture management. If you want a similarly lightweight layer but need sleeve coverage — for sun protection or cooler mornings — the Flow LS Baselayer Top is the better choice. It adds long-sleeve coverage and light warmth for fall or mild conditions. Choose the Pro Mesh when sleeveless moisture management is your priority, and the Flow LS when coverage or a touch of insulation matters more.

The Pro Mesh Sleeveless Baselayer is built around 3D mesh fabric for excellent moisture management, worn skin tight under jerseys for moisture transport. A merino option like the Merino Seamless Baselayer regulates temperature across a wider range and resists odor on multi-hour rides. If you want a breathable, moisture-focused layer, the Pro Mesh is built for that. If your conditions swing cooler or you want one layer that works across temperatures, a merino baselayer fits better.
