Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.051". 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.

Comfortable, warm enough. Feels a bit like a shawl but looks like a good sweater.
I like the color and the fit is good, roomy, feels a bit like a shawl but holds shape and hides a few extra pounds. The zipper is thin but whether you'll find it good enough to last I wouldn't know yet. I'm keeping this.

Comfortable, well put together, nice material, size chart is way off.
Color: Black, Size: 3X-Large
A well put together sweater that is made with very soft yarn, and doesn't seem to have any major structural issues. The zipper works great and the stitching looks like there's not major flaws. The only big issue is the 3XL sweater I got is way off size wise. Oversized sweaters are great, so I was excited about getting this for me to use for day to day wear, and my wife (who is a lot smaller than me) to steal when she's watching tv on the couch or sitting outside, so the disappointment was palatable. Sadly the 3XL size is about the same size as XL sweaters in the closet, where as a few 2xl sweaters we recently ordered from another company are a lot larger than this one. Outside of the major size discrepancy, which could be a major deal breaker for some, the sweater itself is really comfy and really nice. Sadly 3XL is the largest size we could get on the chart.

Well made for the money.
Beautiful, and well made front zipper sweater. I purchased 7 for Christmas and the men in my family loved the soft feel of the fabric. They were true to size..

Very stylish
Color: Khaki, Size: Medium
My husband doesn’t like wearing pullover sweaters because he gets hot after being inside for awhile. This sweater jacket was perfect. It’s stylish and well made. Very comfortable and great price. When I gave him the pkg and reminded me he didn’t like sweaters inside. When he opened it and was pleasantly surprised. Finally he could wear a sweater that was easy to put on and take off. He loved everything about it. I bought more colors and he wears every one of them. Great sweater!
