Runners and lifters add ten balanced pounds with this weighted vest, whose evenly distributed iron sand fill hugs the torso without bouncing through strides and burpees. Breathable neoprene keeps the 15.4 x 13.8 inch vest comfortable against skin, while the adjustable buckle fits men and women snugly and the reflective stripe keeps dawn jogs visible. Storage pockets hold keys and phones through hikes, Hiit circuits, and strength workouts.
