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.

10/10!

I was so happy & excited when my vest arrived & couldn’t wait to wear it in the 10 degree water in the bay (Melbourne). It does exactly what is says…repels the water & keeps you warm. It is comfortable & easy to put on & take off. I may well buy a 2nd one. The sizing is true to size as well. I didn’t need to swap or return. Thank you Shark Eyes.

Love my thermal zip rashie

This was just the perfect layer under my shortie wet suit to keep me snug whilst snorkelling. The front zip means it is not difficult to get into and the wet suit simply glided over the fabric which made that less of a struggle too.!

Toasty!

Very happy with this rashie! I have done a couple of swims in it and have no complaints. It definitely helps keep me warmer in the water. Very happy.
