  • 11/26/2015 Just what I wanted

    5 Review Stars By Jet

    Shirts must be tight but also able to be taken off and on.  This shirt hits that need right in the middle.  It stretches a little after the first wearing, but that was fine.  It makes that first plunge bearable when the water feels really cold.
    Thanks, Mares.


    Fit: Feels true to size

    4 Review Stars By ToddinFl

    This is a great insulating layer for cool weather swimming, snorkeling, and surfing.  I wear it as an additional layer under my shorty wetsuit during the fall and winter months. I recommend this for anyone needing something more than just a swimsuit  and rashguard for warmth

  • 1/12/2014 Lightweight Thermo

    4 Review Stars By JRC

    Was surprised this was a Thermo shirt as it is very light weight. I have a Mares Thermo shirt that is wired for an iPod and it is much heavier. I only wish that the shirts came with a zipper in the back for ease of putting on and taking off. Otherwise, it will be good for snorkeling in water that is still a bit chilly in February in the Caribbean.

    5 Review Stars By monty h.

    I swim laps with the shirt. The indoor pool is cool late at night or early in the morning. The shirt warms me up nicely. I am 6" 1" 64 years old weigh 260; 48 chest 47 waist. It was a very tight fit dry but expanded nicely in the water. It needs to be tight to keep water out and is. The wrists were a little loose; water will come in. I solved this by pulling the sleeves to my forearms. I swim a lot of laps and I do have to keep pulling them up.The botton rides up as I swim. This is more an anatomy problem than shirt. I am going to look at a shorty one piece to solve the ride-up. I am very happy with the shirt. It is often the difference in going to the pool and not and winter has just begun. I like the .5 thickness, very little drag. I don't know about long term but it seems well made.

    I use this top to wear in the swimming pool as it is not heated. Keeps my upper body warm in the cold water. Good product.

    I bought this with the size specifications given. overall out fit heat however the neck seal is too big. Also for the price the material is very thin and cheap. Two thumbs down.
