5mm Wetsuits

A lined scuba suit and an open-cell spearfishing suit can have different dressing and care requirements. Two-piece suits overlap at the torso, while one-piece suits use a continuous body with a zip entry. Choose the design for your activity and follow the specific manufacturer’s fit advice.

Compare lighter 3mm wetsuits, thicker 7mm wetsuits, or return to the complete wetsuit range.

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.

Compare construction in our existing two-piece wetsuits and open-cell wetsuits collections.

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.
