Don't let the comfort fool you. The G-Vest is a secret weapon that raises the challenge (and gains) of your training session. Wear it at the gym, and the difficulty of your workout hits a little quicker. Zip it on before a hike, and you turn an easy out-and-back into a strength and conditioning session. Or wear it at home to give bodyweight workouts a boost. The weight is spread close across the torso, so it feels lighter than its 10 pounds. And with a locked-in fit and pliable feel, there’s nothing holding you back.
