Thickness rule, not a race entry

Panel thickness is not published as a maximum, so this guide makes no thickness-rule reading for this model. USA Triathlon rule 3.2.1b, in the rules dated 2026.01.01, states that a wetsuit may not exceed 5 mm anywhere, and that two pieces stacked in an overlap may not exceed 5 mm together. World Triathlon competition rules section 4.11 d (i), in the 2026 rules file with pages dated 13 December 2025, states the same 5 mm limit and allows a tolerance of 0.3 mm. A figure printed by a brand is not a measurement of the finished suit. It is not approval by World Aquatics. World Aquatics keeps a separate approved-swimwear list. A suit can meet a thickness line and still be forbidden at a warm race. Water temperature, swim distance, and the athlete category decide that. The event referee applies the table.

The temperature tables are on the method page. This site does not call a suit legal, and it does not claim a hands-on test.
