Playtex Women's 18 Hour Active Breathable Comfort (Style 666C)

In this review of the Playtex Women's 18 Hour Active Breathable Comfort Wireless Bra the bottom line is simple: it is best for women seeking a comfortable, non-wired everyday and lightly active bra that stays cool and smooth under clothes. The single biggest reason to buy is the combination of moisture-wicking cups and breathable cup liners that actually help keep skin dry during movement, making it a reliable choice for yoga, errands, or long work days when underwire is not wanted.

Key Features

• Cool Comfort cups: Moisture-wicking fabric in the cups and breathable liners helps pull sweat away and reduces clamminess during activity.
• Wirefree support: The wireless design provides comfortable hold without pressure from wires while still offering structure for everyday wear.
• Smoothing non-foam cups: Smooth cups create a sleek T-shirt bra profile so the bra disappears under fitted tops.
• No-slip cushioned straps: Wide, cushioned straps are designed to stay in place and reduce shoulder strain during active or all-day wear.
• TruSUPPORT system: Support is distributed from the cups through the sides, back and straps to deliver four-way stabilization for light activity.

Who It's For

The bra works well for women who want a comfortable, wireless everyday bra that can handle lightly active days such as walking, yoga, or busy work shifts. It is a good pick for those who prefer full coverage and a smooth look under T-shirts and blouses.

Users who need heavy-impact sports support or highly molded shaping should look elsewhere; this bra is designed for light activity and smoothing rather than firm compression or push-up shaping. Also, shoppers who rely on very exacting size fits may want to try on or check fit guidance since customer reports show mixed sizing experiences.

Pros & Cons

Cons
