cool long sleeve rash guards?

Thanks to the thread recently posted on about hats for sun protection, I ordered an Adventure Hat from Sun Days for the summer. Now I’m looking for long sleeves with high UV protection to swim and paddle in. I’ve got a long sleeve Rapid Style and a Watergirl long sleeve rash guard, but they are nylon/spandex and I think they are going to be really hot in 90 degree weather. Same with a Columbia long sleeve fishing shirt I’ve got. Anybody have any other ideas to save the skin and stay cool while paddling?

Thanks - Jenn

This is basically a 100% polyester long underwear top. I have a men's grey one that I really like - better than the nylon spandex rashie, though not as durable (mine has lasted over three years, though, summer and winter). Get a light colour and they can be quite comfortable - no chaffing around a vest, either.

Of course, similar products from other companies would be good to - Try Pata-Gucci's Capilene, or similar.

probably not great to swim in, but great for paddling - Kokatat Destination Shirt (SPF 40)


I prefer to wear
UnderArmour products as a first layer - in both winter and summer. The stuff wears like iron and is highly functional as a first layer in hot or cold conditions.


works a lot better than sunscreen on the arms

Columbia long sleeve fishing shirt
I have a couple of these types. Wear them all summer long. I think they are cool enough for hot weather wear.

Along with a number of silkweight tops for slightly cooler weather I also have a couple of these in both short and long sleeve for super hot days.

Icebreaker Merino Wool - Skin Layer

I’ve had great success staying cool with Mysterioso tops. Cool patterns to boot (provided you don’t have a problem with Hawaiian Hibiscus Lycra material is actually cold to the touch. Also found out do not wear these when the temp drops below 75-78 degrees. I start shivering. Works even better when wet as the fibers seem to amplify the evaporative air conditioner effect. Also great sun protection.

See you on the water,

They speciallize in sun protection. Their swim shirts are great. Like a rash guard, but loose fitting. Long and short sleeves. I haven't found any similar yet.

Also some very nice super lightweight and quick drying sun shirts.

Shorts, lightweight, long pants, hats, etc...

Downside is price.
