Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.051". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.This Part Fits:

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.

ONE OF THE BEST ON THE MARKET AND GREAT PRICE!
Size: 24 Lb, Color: Pink, Size: 24 Lb, Color: Pink
I received my 24 pound vest today. I ordered pink. I love the color! Upon inspection, I see that the vest is very well-made, sturdy, with no metal beads leaking. It fits great. My previous vest hung down too low, resting on my hips. This one sits much higher, just like I wanted it too. This fits my body pretty great. I wore it inside my house to give it a try for two hours. It never shifted and I did not have to adjust it. However, the bulging sand pockets on my back, pressed against my shoulder blades and were a little bit bothersome, but not painful. I’m sure I’ll get used to it. I have purchased 5 rucking vests from 4 different manufacturers and this one, along with RuKSTR are the best. Unfortunately, RuKSTR does not make a 24+ lb weighted vest.
Here are the stats of my body:
5’9” 142 lbs. 68 yrs old
Bust = 38” Waist = 28”
Midriff = 30”
Top of shoulder to waist = 19”
Shoulders end-to-end = 15”

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.
