For such a thin shirt it helps to keep me warm better than I thought it would, even when soaked with sweat. The fabric breathes well and drys quickly in a breeze. It is a little bit stretchy and hugs my shape well and I find the white stripes down the arms fashionable. I bought two of them for kayaking but wear them when I am out exploring dry ground as well. I got them on sale but believe they are worth the regular full price.
I would buy them again and recommend them for any activity where its important to stay warm when wet. One big plus is after it drys from sweating It doesn't smell like body odor like a cotton shirt does. Great for overnight kayaking trips.
