Quick-dry fabric
A triathlon suit uses quick-dry fabric so the transition into the next leg stays comfortable instead of cold and heavy.
Seams decide how much you chafe
Flat or bonded seams cut friction over a long swim. The neckline seam matters too, since that’s where a wetsuit sits directly against the skin.
Built to go under a wetsuit
Too much compression across the chest can affect breathing once a wetsuit goes on top. A suit that’s overly thick or tight works against that layering.
Compression built for racing, not chlorine
Orca’s Core jammer, brief, square leg, and thin-strap one-piece run on a nylon-elastane compression fabric rather than a chlorine-resistant polyester weave — the same trade-off that makes a suit comfortable under a wetsuit also makes it less suited to daily pool laps. If most of your training happens in a chlorinated pool, a PBT-polyester suit will outlast it; if race day and open-water sessions are the priority, that’s exactly what this fabric is built for.

FAQ
Can I use a regular training suit for triathlon?
You can, but quick-dry fabric and low-friction seams make a real difference over race distance.
Does the same suit work for training without a wetsuit?
Yes. Quick-dry, low-friction fabric helps regardless of whether a wetsuit is involved.
