A true second skin

"Actually, the bag stays so still that you could almost forget you're carrying it while running. Very comfortable. One downside is the lack of a mounting system in the back pocket for a water bladder to make long runs more efficient. Other than that, it's flawless."

Fabrice V. (4/5)

Ultra-lightweight—you'll forget you're carrying it in no time

"First test yesterday—to be honest, I was worried about the fit when I tried it on... even though I'd followed the sizing guide! A 1-liter water bladder, my phone, a few sugar bars, and off we went for 23 km... a few more adjustments during the first kilometer... and PERFECT!"
