Printable Wetsuit Thickness Guide

This one-page wetsuit thickness guide is for swimmers, surfers, divers, paddlers, and triathletes who want a quick way to match suit thickness to water temperature. It lists two columns, water temp and suit, with ranges such as above 75°F or 24°C for a rash guard or 1–2 mm top, 65–75°F or 18–24°C for a 2 mm shorty or 3/2 spring suit, and 58–65°F or 14–18°C for a 3/2 mm full suit. It also notes that wind, activity level, and how cold you run can change the choice.
