經典U型加重背心 - 可調節重量

The U-shaped neckline really does what it promises — no digging into my collarbones even during squats. I’ve worn it for full workouts and forget it's on after the first few minutes, which is rare for a weighted vest.

The adjustable straps make it easy to dial in the exact weight for my workout, and I barely notice it’s there during squats. I was worried about neck strain, but the U-shape sits so naturally that I forget I’m wearing it halfway through my session.

The U-shaped neckline is a game changer—no more digging into my collarbones during squats. I've used it for three weeks now and can actually move through pull-ups without feeling restricted.
