Doesn’t look like a tactical vest
Size: 20lb, Color: Black
Affordable and easy to wear for a nice rucking session around my city neighborhood. Strap design fits comfortably around my shoulder. Tends to rub my traps after a long session, but that could be due to posture. Clips securely but straps are too long. Fits under hoodie very nicely.

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: 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.
