IT'S FINALLY HERE! Under Armour® is now available on Zappos.com!

It started with a simple plan to make a superior T-shirt. A shirt that provided compression and wick perspiration off your skin rather than absorb it. A shirt that worked with your body to regulate temperature and enhance performance.

Founded in 1996 by former University of Maryland football player Kevin Plank, Under Armour® is the originator of performance apparel - gear engineered to keep athletes cool, dry and light throughout the course of a game, practice or workout. The technology behind Under Armour's diverse product assortment for men, women and youth is complex, but the program for reaping the benefits is simple: wear HeatGear® when it's hot, ColdGear® when it's cold, and AllSeasonGear® between the extremes.

Under Armour’s mission is make all athletes better through passion, design and the relentless pursuit of innovation. 

Take advantage of the warmer weather by taking your running sessions outdoors. Start off with the perfect pair of running shoes like the ever-popular ASICS. Taking the time to pick the correct type of running shoes for your pronation type is key to avoiding injuries on those long runs on concrete and asphalt.

When running outside in heat and humidity, it’s essential that you pick lightweight clothing with moisture-wicking properties. For women, try the sleek Fizz Tank II from Sugoi and the Adidas Stella McCartney Running Performance Short. For men, pick a comfy muscle tank, like the Adidas Response Tee, to keep cool on your run. A pair of lightweight shorts like the Nike Four-Inch Woven Short is a good basic.

Running outside also calls for some extra safety precautions. Here are 5 tips to make your runs safer and more comfortable:

1. When listening to music, keep the volume low enough so you are able to hear cars and cyclists. Never assume that a car can see you.

2. Run facing the traffic.

3. Be careful not to run on paths where you are consistently on a slant. This is very hard on your hips and knees.

4. When running in low light conditions, wear reflective materials.

5. Wear sunscreen when running in the daytime. SPF 30 or above is best.
