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.

Very flattering design
Love it!
Excellente qualité
Tissu et confection de qualité, design parfait pour nager.

Parfait
Seyant
Convient bien pour l'aquaforme
Maillot natation
Doublure de soutien gorge intégrée. Très flatteur.
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.
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.
