Very comfortable
Size: 8lb, Color: Black, Size: 8lb, Color: Black
Love my weighted vest. It fits comfortably and the pocket holds my phone while I walk. It’s not too bulky so in inclement weather I can wear it under a jacket. My posture and walking pace has improved since using my vest everyday.

How much weight are you carrying?
Size: 16lb, Color: Black
I’m very pleased with my 16lb weighted vest. Great quality. The straps are easy to adjust and the weight is evenly distributed when wearing. It really helps with your posture. Great way to ease in on training for backcountry hiking/camping.

Comfortable Fit & Great Added Challenge
Size: 8 Lb, Color: Black, Size: 8 Lb, Color: Black
Really impressed with this vest. It fits snug without being bulky and stays in place during walks and workouts. The weight feels evenly distributed, so it’s comfortable on my shoulders and back. I’ve been using the 8 lb option and it’s the perfect way to add a little extra challenge to my routine. Easy to put on, well made, and definitely worth it!

comfortable and works
Size: 10 Lb, Color: Black
Finally figured out how to wear this vest. There are two sides to the vest. When I put it on upside down, it fits much better and is comfortable. I bought the 10lb vest and although it feels heavy when you pick it up, its very comfortable when wearing it. If I put it on right side up it does not fit across my chest. But turned around it fits great and I am able to buckle it closed. I definately stand up straighter when wearing this vest and easy to walk around it. Although, as the weather gets hotter, it is a bit warm to wear.
