Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.040". With MID Sleeves. 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.

Showstopper! Incredible Fit and Stunning Floral Design!
Size: Medium, Color: Black
I bought this Mgnaie floral tuxedo for a special event, and I was absolutely blown away by the quality and the fit! Getting a slim-fit suit online can be a gamble, but this two-piece set fit perfectly right out of the package. The blazer hugs the shoulders beautifully, and the pants have a modern, sleek profile without being too restrictive or tight. The floral pattern is exactly what I wanted—bold and eye-catching, yet elegant enough for a formal setting like a wedding, prom, or gala. I received compliments all night long! The fabric feels premium, breathable, and comfortable enough to wear and dance in for hours without losing its shape. For the price, you are getting a high-end look that rivals much more expensive designer tuxedos. If you want to stand out from the crowd in the best way possible, I highly recommend this suit. It is an absolute must-have for any formal wardrobe!

Very high quality suit for the price! Might as well buy, then rent.
Color: Deep Grey (Stretch Fabric), Size: X-Small
I bought this for my son for his Prom, as he decided to go last minute. He weighs around 125 pounds and is about 5'11. The XS fit was pretty amazing. As the supplier says, follow the size chart on the second picture. There is also some stretch to the material and the pants have belt loops. The only thing we noticed that we didn't like is that the sleeves were a little large at the opening around the wrist. Since the cuff-links are sew on, there isn't really on easy way to adjust this. All in all, this was a great purchase and I would highly recommend YND suits.

Good buy for sure.
Color: Burgundy (Stretch Fabric), Size: X-Large
The suit looks and feels great for the price I’m 6’3 190-200lb and ordered a size XL. I’m going to have the sleeve dropped a tad bit and waist taken in. The hem is perfect and to my liking. Will be buying 2-3 in the future.

We’re happy!
For the price, this suit was great. My son is a bigger guy and when we rent tuxes, the pants always look terrible. This one, we were happy with. He usually wears a 2x in clothes but we sized up to the 3x. He’s 6’2” and prob 270. Maybe more but the vest was still a little snug.
