Can a fabric be too comfortable to wear while diving? I’ve been wearing this rashguard for my last 5 dives and I’m still not tired of it. It provides great protection from the sun as well.

So soft and light. Perfect for calm waters. Does it withstand rough waters though?
Imran Hanafiah –
Thank you for your review, Rachel. We’re glad you’re enjoying the softness and lightness of the Mares Thermo Guard Rashguard. However, this product is designed to provide protection for calm waters. For rough waters, we recommend a thicker or specialized rashguard suitable for such conditions. If you have any further questions or concerns, please don’t hesitate to ask.

How does this compare to other dive rashguards in terms of water resistance and warmth?
Junhao Lo –
Hello Aqeelah, thank you for your review of the Mares Thermo Guard Short Sleeve Rash Guard! In terms of water resistance, the 0.5mm neoprene material provides excellent protection against the elements, making it suitable for smooth skin divers. Many divers have reported that it is on par with other leading brands in terms of water resistance. Regarding warmth, the Thermo Guard offers great thermal insulation due to its neoprene material, allowing divers to stay warm in cooler water temperatures.

This has been one of my favorite diving companions. The 0.5mm thickness keeps me warm even in cold waters, and the short sleeves offer excellent mobility.
Nor Hashiela Binte Tahir –
Does this particular rashguard have any issues with snags or runs, as the material seems pretty thin?
Imran Hanafiah –
Thank you for your question and for sharing your thoughts on our Mares Thermo Guard Short-Sleeve 0.5mm Men’s Rashguard. Unfortunately, we’ve had no reported issues with snags or runs on this particular product, even with prolonged wear and tear. However, please note that as with any thin material, minor snagging might occur if you rub against abrasive surfaces. To minimize this risk, we recommend washing it in cold water and drying it flat. If you have any further concerns, feel free to ask and thank you for choosing us!
