Now that we're coming up on the end of August, the mornings and evenings are beginning to cool down. If you love to workout during this time of day, your shorty shorts and tank top just aren't going to cut it. You'll need a thin extra layer to keep you warm.
I absolutely love this Capilene 1 Scoop from Patagonia. It's soft, silky, and very comfortable. You can layer it over a tank top, or wear it right next to your skin (it's not at all itchy like some wool baselayers can be). It will wick away sweat, dry fast, and keep you warm. If you get too hot, you can easily slip it off and tie it around your waist (it's so thin and lightweight, you won't even feel it).
It's highly breathable and made of polyester that's 100% recycled, and also 100% recyclable through the Common Threads Recycling Program. Usually polyester can retain odor, but this Capilene has Gladiodor™ natural odor control, so it won't stink.
This is a must if you like working out in late Summer/early Fall weather. Order it for $38 in Black, White, Wild Poppies (Pale Blossoms), Wild Poppies (white), or Tinted Ice.
