Product Insights
The Quantum Accent Stripe One-Piece delivers durable, lap-swim performance with PowerFlex Eco fabric that retains shape 10x longer than traditional swimwear, resists chlorine, and includes recycled ECONYL, plus a racerback design and side panels for stable support and unrestricted arm movement—yet runs small, requiring at least one size up, especially for larger busts, and may show some elasticity loss and fading after six months, needing immediate rinsing and air drying to maximize longevity.

A one-piece made for regular lap swimming and pool workouts
This athletic-fit Speedo one-piece is designed for swimming performance, with a chlorine-resistant PowerFlex Eco fabric and a racerback meant to allow unrestricted movement through the water. Reviewers report the quality fabric and stitching hold up to regular lap swimming and aqua fitness. If you have a larger bust, reviewers note the suit runs tight in the chest, and many found sizing up one size resolved this while still providing support.[1]
For lap swimming and aqua fitness classes

Reviewers describe quality fabric and stitching that hold up to regular pool use, and one reviewer noted the suit stays in place during water workouts.

Product comparison
Compared within this brand.
| Quantum Accent Stripe One-Piece: Choose this if you want an athletic one-piece for lap swimming or water workouts: it's made with chlorine-resistant PowerFlex Eco fabric, has a racerback for unrestricted movement, and one reviewer noted it stays in place during aqua fitness classes. It includes a built-in shelf bra with soft cups and removable foam padding, with a bikini cut, high-cut legline, and full seat coverage. Note that reviewers consistently report the sizing runs small—especially in the bust—so consider sizing up one size, which many say still provides support.[1,2] | Sculpture Boom Cross-Strap Trimmed One-Piece: Choose this if you want a one-piece for dynamic swimming with shaping support: Speedo describes its Sculpture fabric with LYCRA XTRA LIFE as chlorine-resistant, zero-pilling, and gently contouring, with a front powermesh liner and soft cups with removable foam padding. The Boom Back with wide crossed straps is designed for flexibility and freedom of movement, and the suit comes in a classic fit with four-way stretch, a scoop neckline, and a regular bikini cut. It is offered in Patterned Blue (navy with mint green trim) in sizes 32 to 38 only, so it may not work if you need other sizes or colorways.[3,4,5,6] |

J'aurais dû prendre un point plus grand
Très bonne qualité, photo et réalité sont pareil. Serré un peu du buste car j'ai une forte poitrine, j'aurais pu prendre un taille 10 au lieu d'un taille 8.

Convient bien pour l'aquaforme
Excellente qualité
Tissu et confection de qualité, design parfait pour nager.

Very flattering design
Love it!
If only it had fitted
Far too small so had to return. Checked size chart so should have been ok.

User inquires about Quantum Splice fit and comfort
I can't say if the quantum splice is good or not, I've never been much of a fan of the thicker straps but it wouldn't hurt to try it on and see if it fits your body well and feels comfortable when you move your arms.

Probably something close to the Quantum Splice that has worked well for me.
