Is this top good for layering?

Yes. The full zipper lets you wear it open over a tank or closed as a base layer. The regular length keeps it from bunching under jackets.

Does polyester make it hot to wear?

It can. Polyester does not breathe like cotton, so it feels warmer and can get clammy in heat or during hard exercise. It works best as a light outer layer or in cool weather.

How does the sizing run?

It comes in S through 3XL. The cut is regular rather than oversized, so check the size chart against your bust and waist measurements before choosing.

Can I machine wash it?

Yes, polyester is machine washable. Wash cold and skip high heat in the dryer to avoid shrinkage and static buildup.

The solid polyester knit is generally opaque in darker shades. Lighter colors may show more under bright light, so a nude or matching underlayer helps.
