FREQUENTLY ASKED QUESTIONS

How is this different from a regular rash vest?

Unlike regular rashies that become soggy and cold, our thermal rash vest is made from hydrophobic nylon fleece. It repels water, retains warmth, and dries quickly – keeping you comfortable for longer.

Can I wear it on its own or only under a wetsuit?

Both. It’s perfect as a standalone layer in mild conditions (recommended for 18–24°C water) and as an extra thermal layer under a wetsuit in colder conditions.

Is it suitable for all water sports?

Absolutely. Whether you're surfing, diving, foiling, spearfishing, or just paddling out, this vest moves with your body while offering serious warmth and sun protection.

Will it stretch out or lose shape over time?

The 4-way stretch fabric is built for durability. It holds shape through repeated wear, rinsing, and sun exposure.

Does it offer UV protection?

Yes – 50+ SPF sun protection to guard you on long sessions in the sun.

Great for Kayaking

Soft, flexible, didn't need any other layers on a crisp morning out on the water. Nice how the water beads off as it was raining a littlezzz Also didn't get too hot when i really got going. I'd like it in a forest green. Or a turqouise.

Amazing tolerance in ice water

I wish I had known about shark eyes before our winter. I could have continued my aquatic therapy. Thermol shirt allows me to to tolerate in icy water. the fit is true to size. I hope I can match thermol leggings for all year round ocean pool swimming.
I highly recommend shark eyes to everyone in particular people who cannot tolerate chlorine and heated pools. 10/10
