Great product but lead times and out of stock levels must be updated.

Out of stock (website wasn't updated) and will only receive in 6 weeks from order. Will record a review then. However, i did get a phone call to apologize with the option of a refund which I did not take up and prefer to wait. I really like the short sleeve product i purchased a few weeks prior although size was also out of stock (website not updated). Settled for a smaller size after a courtesy call from Radiator. A pity as the product I currently have is simply phenomenal - points lost purely on website out-of-stock levels not updated for quite some time and could be misleading to some.

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.
