What is a cycling mid layer?

A mid layer is the insulating piece between your base layer and outer shell. It traps a layer of warm air while still breathing, so you stay warm on cool rides without overheating on the climbs. Thermal long-sleeve jerseys and wind vests both work as mid layers.

Mid layer vs. base layer vs. jacket?

The three work as a system: a base layer wicks sweat next to your skin, a mid layer adds insulation, and a jacket or vest blocks wind and rain on top. Add or shed the mid layer to fine-tune warmth as conditions change.

When do I need a mid layer?

Reach for one on cool and cold rides, long descents, and days with big temperature swings. A packable mid layer is easy to stash in a pocket once you warm up.

Can a long-sleeve jersey be a mid layer?

Yes. Thermal long-sleeve jerseys and wind vests double as mid layers, adding warmth over a base and under a shell. For dedicated cold-weather tops, see Cold Weather Cycling Jerseys .

How should a mid layer fit?

Close enough to layer smoothly over a base and under a shell, with room to move and no bulk that bunches. Check our Size & Fit Guide if you're between sizes.
