Solid and comfortable vest
Size: 30lb, Color: Black
This vest is solid. Fits good, feels strong, and the weight sits right without being annoying. I like it for workouts because it adds that extra push without making it uncomfortable. Definitely worth it.

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: 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!
