speedo Women's One Piece PowerFlex Princess Seam Ultraback - Modest 5

In this review of the speedo Women's One Piece PowerFlex Princess Seam Ultraback, the bottom line is simple: this is a conservative, durable one-piece built for regular lap swimming, water aerobics, and modest poolside wear. The suit's single biggest reason to buy is its trademarked Xtra Life Lycra, which is designed to resist bagging and sagging so the suit retains shape over repeated chlorine exposure. The soft cup bra construction and vertical princess seaming make it a practical choice for swimmers who want coverage, gentle shaping, and a reliable fit during active water exercise.

Key Features

• Xtra Life Lycra: fabric that lasts 5 to 10 times longer than traditional lycra, providing long-term resistance to stretching and degradation.
• Chlorine and oil resistance: resists the effects of suntan lotion, skin oils, and chlorine so the suit looks and fits like new for longer.
• Conservative cut with soft cup bra: offers modest coverage and light bust support for comfort during aerobics or lap swimming.
• Princess seaming: vertical seams provide a slimming visual line that helps trim the torso without restrictive compression.
• Ultraback design: a higher back provides secure coverage and ease of movement for swimming and water workouts.

Who It's For

The suit is best for women who prioritize coverage, durability, and a straightforward silhouette for regular water exercise. It suits lap swimmers, water aerobics participants, and those who prefer modest one-piece styling with light bust support rather than competitive cut suits.

Swimmers who want maximum compression or race-focused hydrodynamic cuts should look elsewhere, and buyers expecting padded shaping or heavy-duty underwire support will find the soft cup construction provides only moderate support.
