Obrien Elite 3/2mm Back Zip Wetsuit - Black - 12

The 3/2mm thickness is typically best for mild to cool conditions. Depending on your personal cold tolerance, it may be used in winter, but consider a thicker suit if you are in extreme sub-zero water temperatures.

This model is a UK size 12. Since wetsuits are meant to fit like a second skin, ensure your measurements align with the manufacturer's size chart for a snug but comfortable fit.

Yes, the flexible neoprene allows for the natural stroke pattern required for swimming, making it a viable option for open-water training.

A gentle soak in fresh water or a light rinse with a specialized wetsuit shampoo will effectively remove salt and odor without damaging the neoprene.

If the zipper becomes stiff, you can use a small amount of dedicated zipper wax or a non-petroleum-based lubricant to ensure it moves smoothly.

Ensure the internal flap is smoothed out flat before pulling the zipper, and try to reach behind your back with both hands to keep the suit material taut.

Check that the size is correct; a wetsuit that is too loose will allow water to circulate. Ensure the neck and wrist cuffs are pulled tight against your skin.
