เสื้อถ่วงน้ำหนักรูปตัว X คลาสสิก - น้ำหนักคงที่

The iron sand filling is packed evenly enough that it doesn't shift or dig into my shoulders during workouts. I went with the 20 lb option and the X-straps keep everything snug without restricting my range of motion.

The X-shaped straps stay put through burpees and sprints, no shifting or digging into my shoulders like my old vest. The 20 lb version feels dense and balanced, and it’s comfortable enough that I forget I’m wearing it until the burn kicks in.

The iron sand filling sits so evenly that I forget I’m wearing it during warm-ups, and the X-shape keeps the weight from shifting even when I’m doing lunges. Been using the 20 lb version daily for two weeks now, and the straps haven’t dug into my shoulders once.
