speedo Women's One Piece PowerFlex Princess Seam (Style 1740)

In this review the speedo Women's One Piece PowerFlex Princess Seam Ultraback is judged primarily on durability and fit for active swimmers. The bottom line: this suit is best for women who want a conservative, stay-put one-piece for lap swimming, water aerobics, and regular pool use because its PowerFlex and Xtra Life Lycra fabric resist sagging and fading while providing medium built-in bust support. The princess seams create a slimming vertical line without sacrificing coverage, and the Ultraback cut provides secure shoulder straps for confident movement.

Key Features

• PowerFlex fabric: Provides a long-lasting material that stands up to repeated pool sessions and resists bagging compared with ordinary spandex.
• Xtra Life Lycra: Keeps the suit looking newer for longer by resisting chlorine-related fading and sagging for extended value.
• Compression technology: Improves circulation for faster muscle recovery and reduces chafing during lap sets or water exercise.
• Built-in bust support: The soft cup bra construction and medium support cups hold the bust comfortably for less bounce during active use.
• Lotion and oil resistant: The material stays put in the water, reducing slips and the need for constant readjustment while swimming.
• Princess seam design: Vertical seams add a slimming silhouette while keeping the conservative cut appropriate for modest coverage.

Who It's For

The suit is ideal for women who regularly swim laps, attend water aerobics, or want a reliable one-piece for beach and pool days with modest coverage. It suits swimmers who prioritize a secure fit, reduced bounce and long-lasting chlorine resistance over fashion-forward, trendy cuts.

Those looking for a highly revealing or fashion-first swimsuit, or who require extreme compression targeting competition swim times, should look elsewhere. Also, buyers who need exacting sizing should check fit notes carefully, as some customers report the sizing runs slightly large for certain body shapes.

Pros & Cons

Pros

• Long-lasting fabric resists sagging and fading so the suit keeps its shape after many swims.
• Comfortable medium bust support with soft cup construction reduces bounce in active use.
• Chlorine and oil resistance means the suit stays in place and maintains coverage during workouts.
• Slenderizing princess seams create a flattering, conservative silhouette suitable for modest wear.

Cons

• Sizing received mixed feedback, with some customers finding it a bit large and others saying fit is spot-on, so trying or checking size guidance is advisable.
• A few users report material deterioration over long periods despite the Xtra Life Lycra claims, which may vary by usage and pool conditions.
