🧊 Why a Good Wetsuit Matters

A wetsuit acts as thermal protection, trapping a thin layer of water between your body and the neoprene material. This water warms up to your body temperature, keeping you insulated against cold ocean temperatures.

Key Factors to Consider When Buying a Wetsuit:

✔ Thickness – Determines warmth (3mm for warm water, 5mm-7mm for colder conditions).
✔ Material – High-quality neoprene ensures flexibility and comfort.
✔ Seams & Stitching – Flatlock seams for warm water, glued & blind-stitched for colder temperatures.
✔ Fit – A snug fit prevents excess water from flushing in and out.
