Works like a champ. Hope it lasts a long long time. Stuff is too expensive these days, but what isn't?

Got the thermal swim shirt in late Nov./early Dec. 2013. Fabric seems to be wearing out...has worn spots in armpits and on the front.

These thermal shirts are extremely comfortable to wear for an extended time even in the hot sun at the beach. They are extremely soft inside and are easy to take on/off despite how tight they are while on. The first few mins in the pool/sea is def still quite cold but they warm up pretty quick and are very comfortable after. The only suggestion I would have is that the neckline is uncomfortable. It fits pretty high up and is tough with no give. It also would be great to have a higher neck in the back to protect the neck from the sun.

I teach swim lessons and am in the water about 25 hrs a week. Our pool is kept around 81/82 degrees fahrenheit. I love how warm it keeps me. The shirt unfortunately wears out quickly and stretches to the point that it doesn't provide the warmth I need. I ordered a size down on my last shirt and it seems to be holding up better.
