3mm Wetsuits

Full suits cover the arms and legs; shorties leave more skin exposed. A 3/2mm designation indicates different panel thicknesses, so check each model’s construction. Lining, seams, fit and activity affect warmth as well as neoprene thickness.

Compare 5mm wetsuits for a thicker option, or explore all wetsuits by style and intended use.

Check the model’s size chart and choose a close fit that allows comfortable breathing and movement. Ask our Hallam team for help choosing a suit for your activity and planned conditions.

Explore activity-specific collections: freediving wetsuits and spearfishing wetsuits.

Use the size chart for the exact model and take the measurements it requests. A wetsuit should fit closely while allowing comfortable breathing and the shoulder, hip and knee movement your activity needs. Ask our Hallam team if your measurements fall across sizes.

Follow the suit manufacturer’s dressing, rinsing, drying and storage instructions. Keep sand and salt away from the zip, avoid sharp objects and fingernails, and check compatibility before using a cleaner or lubricant. Open-cell interiors and dry main zips can need different care from lined neoprene and conventional zips.
