Why We Like The On Running Performance Top

Any seasoned runner can affirm the advantages of running in synthetic layers. The On Running Performance Top is engineered to keep you mobile and comfortable on your most demanding runs. The tear-proof front fabric dries quickly when you're logging long miles on warm days while the breathable mesh back provides ventilation for enhanced cool comfort. The back yoke keeps you mobile while the fully taped, seamless design of the shirt eliminates rubbing and hot spots to keep you comfortable while you race and train. Lastly, the slim fit offers an enhanced range-of-motion to adhere to dynamic movements on your journey.

Lightweight, cool top--not seamless

I've put it through the wringer
Size Bought:
5' 4"

The price on this top is ridiculous but it's a nice top. It doesn't hold substantial amounts of sweat and cling like many tops. Even when I'm profusely sweating for hours, it's cool and comfortable. The design used on the back of the top seems to help keep the top from just clinging to my back by offering a little more airflow. The cut is slim, which I like. It's comfortable under my hydration vest too. The description says that this is fully seamless, yet there are seams on the back and sleeves. Do be aware that the white top is rather see through, and the neckline is wide enough that it may not cover the straps of racer-back bras. Edit: Down-voted this by two stars because the back started pilling after a fastpacking trip. This top isn't durable enough for wearing a pack.
