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.

A Traditional Tee that's Fun to Wear
Size: Large, Color: Navy, Size: Large, Color: Navy
Here is a classic fitting tee-shirt that combines a soft feel along with a rugged outdoor look. A top priority for me is comfort and this graphic tee is 100 percent cotton that moisture-wicks sweat away and is non-itchy! Made by Pioneer Camp, the navy blue top is a good fit in medium that is not too tight nor baggy. Staying cool is important and the micro-ventilation fabric is wonderful whether I'm at the gym doing aerobics or running errands. There is a Mont Blanc graphic logo that adorns the upper right corner of this tee, however, it's small and unobtrusive. So, whether you are into hiking, traveling, yoga or just lounging, here's a short sleeve tee that delivers.

Soft and breathable
Size: Large, Color: Navy, Size: Large, Color: Navy
Nice and comfy tee. I love the minimalist design and how fresh it feels. I ordered a size Large and I’m 5’1, 151lbs, jeans size usually 8/29. It fits on the fitted side but with extra room for comfort. This a nice t shirt for daily wear or outdoors. I don’t hike a lot so I’m not sure what people look for in hiking tops. I love the color scheme and quality; and it’s 100% cotton! I do feel like it’s slightly overpriced but if you’re looking for a good quality tee or something to gift I do think it’s worth it.

A great shirt for me to wear to work
Size: Medium, Color: Navy, Size: Medium, Color: Navy
I ordered this shirt to wear to work because I’m pretty active at my job and need to move around comfortable. I’m 5’0 and around 115lbs, but people with the same measurements can have different body types - however I will say that the shirt fit me very well, had a loose fit, but not too loose, just comfortable and easy to move around while wearing. I wouldn’t say it did anything different in warm temperatures than any other shirt I own, but at least it don’t make me hotter. The fabric feels nice and good quality. After a handful of washes, the color still looks great so I have hopes that it won’t fade and look worn right away. It honestly looks exactly like the pictures. The majority of clothing items I’ve ordered off Amazon had left me very disappointed, so this was a very pleasant surprise!

Soft, comfortable, more of a casual tee than performance
Size: Medium, Color: Navy
This is a really comfortable shirt. The fabric is soft right away and it fits well without feeling tight or awkward. It drapes nicely and just feels easy to wear. I wouldn’t really call it a true moisture-wicking workout shirt though. It feels more like a soft cotton tee than anything performance-focused. I haven’t worn it for anything super active, but based on the material it doesn’t seem like that’s really what it’s best for. That said, for casual wear, travel, or light activity it’s great. Comfortable, breathable enough, and the graphic is a nice touch without being over the top. Overall, I like it. Just go in expecting a comfy everyday shirt, not a high-performance athletic one.

Worn, lived in feel
Size: Medium, Color: Navy
The material is soft and breathable, with limited stretch but has a comfy worn feel. The fit is loose with a boxy straight cut, and hem that falls on or just above hip. The color is as seen in the pictures; a deep navy blue with logo print on the upper chest. It’s an everyday anytime kind of t-shirt. Looks great with leggings, jeans, shorts, etc.
