The accepted standard neoprene thickness for warmer summer activities or high energy activities requiring a greater degree of flexibility. There is also a degree of industry accepted tolerance for this thickness of neoprene. Neoprene thicknesses of less than 2mm are designed for high energy activities or tropical environments where less thermal protection is required but naturally have a greater degree of flexibility.

5/4/3mm, 5/3mm
The accepted neoprene thicknesses for year round activities, winter activities or activities in cooler waters. These suits can also have a combination of neoprene thicknesses to create greater flexibility, where required arms/shoulders/legs, providing greater freedom of movement for higher energy activities. Thicker neoprene provides greater warmth but less flexibility.

7mm, 7/5mm
The accepted neoprene thicknesses for year round activities, winter activities, activities in colder waters or any watersports activity requiring greater thermal protection although resulting in lesser
