I've worn this style of Coolmax t-shirt from New Balance for years. The soft fabric wicks away sweat. The sleeves are just the right length to help prevent sunburn yet not get in the way of vigorous arm motion. The shirt is made of a UV-filtering fabric for an SPF of 20. They have also added reflective trim for night safety.
This high tech crew neck shirt has some nice styling. The sweat-wicking polyester/spandex fabric also is rated UPF 50+ to block damaging sun. The contrasting color areas are mesh inserts for air flow on the back and along the ribs. It has flatlock seams to help prevent chafing. Comes in sizes xs through XL Buy Direct and in plus sizes 1X - 3X Buy Direct
This lightweight shirt has mesh panels to keep you cool and the DRYROAD fabric will wick away sweat. It comes in a semi-fitted design to keep you stylish on warm weather walks. It comes in a variety of colors and sizes XS to XL. It has a back zip utility pocket for your MP3 player, energy gel or other small items.
This fast-drying shirt is made of soft pointelle polyester fabric. It will also shield you from the sun, with an SPF of 30, and it is treated to be odor-resistant. It has a slightly slimmer fit and comes in several colors. The size range is XS to XL.
I rarely go sleeveless as my walks are long enough to risk sunburn. But if you like to bare your shoulders, this tank will help you keep cool and dry with its soft pointelle sweat-wicking fabric. Like their crew shirt, it provides SPF 30 for the areas it covers and is treated to be odor-resistant. The flatlock seams help prevent painful chafing. It comes in sizes XS-XL.
Zoot specializes in triathlon clothing. Walkers will appreciate this tank style built to go the distance. It has a racerback design with a built-in Biowrap sport bra. It also has a side stash pockets for your small essentials such as ID and an energy bar or MP3 player. Naturally, it is made with sweat-wicking fabric. It comes in sizes XS to XL.
Like their Velocity t-shirt, this sleeveless shirt has a side pocket suitable for your iPod, ID or other small essentials. The neck and armpits are just the right cut for getting good ventilation. The soft sweat-wicking fabric will help keep you cool.
One More Mile has fun designs and slogans on shirts made of soft, sweat-wicking fabric. Unfortunately, they change slogans over time and did away with my favorite, "Walkaholic." If you see one you love, snap it up. At a recent marathon expo I spied this "I Know, I Know, I'm Almost There," which is what everybody tells you in the last mile of a race. Also seen, "I'm not slow, I'm just getting my money's worth from the entry fee," "26.2 miles - what could possibly go wrong?" It's fun just to browse and laugh.
The Dry-Fit fabric is soft and light and will wick away sweat. We have walker-slogan designs in both women's fit v-neck and in unisex crewneck shirts. Sizes from small through 2X. The women's designs come in either pink or white. The unisex designs come only in white.
