Great work out product
Size: 15 Lb, Color: Black
Zeerun Weighted Vest is most definitely a great product. I am plus-size with large shoulders. This product fits great, the clasp is adjustable, and the padding is soft and comfortable. I don't worry about it holding up. I've been using it for about a month it has great stability, and it's not bulky.

Comfortable fit allows full range of motion
Size: 12 Lb, Color: Purple, Size: 12 Lb, Color: Purple
This is a powerful tool to have in your workout arsenal. The vest is made well; exactly as pictured and described. I ordered mine in purple and thought it would feel bulky and heavy because I struggled with the weight of the box.
However, as I took it out of its packing and it unfolded, I felt the weight change. It slipped on easily and adjusting the chest strap went quick and has stayed secure.
It feels good on; comfortable, stays in place and does not hinder arm movements. The padding sounds like sand(?) and conform to my body thus avoiding pressure points or places of pain.
It does not make me hotter than my workouts normally would, nor does it encourage excessive sweating.
I am 100% happy with this vest and as I get stronger I will purchase a heavier one from this company.

Adjustable Weighted Vest for Stronger Workouts
Size: 10 Lb, Color: Black
Training feels more intense and controlled with this Zeerun Weighted Vest, designed to add extra resistance during walks, workouts, or cardio routines. The weight is distributed evenly, helping maintain balance while increasing workout intensity without feeling overly restrictive.
The adjustable buckle system allows for a more secure fit across different body types, which helps keep the vest stable during movement. The reflective stripe is a useful detail for visibility during early morning or evening outdoor workouts.
The material feels comfortable enough for longer sessions, and the design allows natural movement while still adding resistance to everyday exercises like walking, jogging, or bodyweight training.
It’s a practical way to increase workout difficulty without changing a full routine.

Weighted Vest
Size: 24 Lb, Color: Black, Size: 24 Lb, Color: Black
it’s going to feel heavier than 25lb if it’s your first time with a weighted vest but the quality is top tier, it’s easy to put on and remove, very fitted and adjustable, it comes with pockets to store little things while on your walk or run. wouldn’t recommend washing this unless it’s being washed outside and hung up to air dry but overall perfect for a good workout.

Simple, Comfortable, and Exactly What You Expect
Style: Rack with 3 Pairs (5, 10, and 15 Pound)
These are pretty much exactly what you want from a set of dumbbells — simple, functional, and no nonsense. The neoprene coating gives them a comfortable grip and keeps them from feeling slick in your hands, especially during longer workouts or if your hands get sweaty.
The coating also helps keep them from banging up floors or making as much noise compared to bare metal weights, which is nice if you’re working out at home.
Weight accuracy seems fine for general fitness use, and they’ve worked great for things like accessory movements, shoulder work, lighter presses, rehab-style exercises, and general muscle toning. The shape also helps keep them from rolling around everywhere when set down.
They’re not fancy, and they’re not trying to be — they’re just dependable dumbbells that do what they’re supposed to do at a fair price.
If you want straightforward hand weights for home workouts without overthinking it, these are a solid buy.
