    FAQs

    One-piece or two-piece?

    One-piece is faster (more aero, no transition flap). Two-piece is more comfortable for longer races and bathroom breaks.

    Should it feel tight in the water?

    Yes. A snug tri suit is more aero in swim and bike. Loose fabric drags in water. Should not constrict breathing or arm movement.
