Still the best!

What can I say?
I'm fat and I'm old and I need all the help I can if I'm having a decent length session! Radiator, still the warmest and the lightest.

Above my expectations

I am a dedicated dive professional, currently an active PADI Open Water scuba instructor, based in northern Greece. Given the year-round diving conditions with a wet suit, I sought un underwear thermal protection that is not only easy to put on but also efficient and durable. My search led me to the Radiator thermal vest with long sleeves, and it exceeded all my expectations.
The vest boasts an excellent fit, providing unparalleled freedom of movement while delivering a level of thermal protection significantly higher than standard neoprene vests. The use of high-quality materials and meticulous production contribute to its exceptional performance.
Beyond its impressive features, the Radiator thermal vest stands out for its perfect quality-to-price ratio. Additionally, the customer service associated with this product is of the same high standard as the material itself. I wholeheartedly recommend this thermal vest to anyone, like myself, who spends considerable time in the water and seeks a product with no compromise on quality.

Over the moon with this top.

This fits like a second skin. I can wear a thinner wetsuit for longer surfing. Keeps warmer in winter. Easy to get on and off. Absolutely an essential item in my wetsuit collection. My second one in 10 years.

Looks good, feels good

Light weight and flexible vest feels good on and allows free movement to swim. The vests have a flattering shape with the blue and the red tops having inserts under the arms.
I am pleased with my purchases and recommend others to try.

Warmest rashie you can get

These rashies are by far the warmest you can get. I don't love the cold water at all but with this rashie I am still surfing in boardies and it is nearly May.
If the water gets freezing you can wear it under your steamer. The rashie is as warm as a spring suit I recon.
