Instant Swim · Karma® Collection
Size
Length
The Karma cuts higher at the leg and crosses at the back — not for aesthetics alone, but for hydrodynamic efficiency. Every seam is placed to stay put through flip turns, open-water entries, and 2km sets without a single tug.
The fit question
High-cut legs sound incredible until they dig into hips. Cross-backs look sleek until straps slide. The Karma solves both with thick fixed-back straps that distribute weight evenly and a leg line engineered to sit at the hip crease — not above, not below.
Most swimsuit brands offer one length per size. Karma comes in Regular and Tall (5'8+) across 7 sizes — XXS (26) through XXL (38). If you're over 5'9" and tired of one-pieces riding up, the Tall option adds torso length where it matters.

What makes this special
Fixed thick straps that stay put through racing turns and distance sets.
Regular and Tall (5'8+) — finally, torso length that actually varies.
Recycled yarn and recovered ocean plastic. Performance without virgin synthetics.
Speed-efficient cut that elongates without exposing. Sits at the hip crease.

Performance + conscience
Most eco swimwear is lifestyle-only — pretty but not built for lane swimming. Most performance swimwear ignores sustainability entirely. The Karma sits in a narrow niche: genuine racing-cut efficiency in Luxe Eco fabric sourced from recovered ocean plastic and recycled yarn.
