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

Lightweight, Stylish, Moisture-Wicking, Breathable & Stretchy
Color: Bluedotwhite, Size: Large, Color: Bluedotwhite, Size: Large
I picked up this Alex Vando polo in bluedotwhite to add to my polo collection, and overall I’m pleased. The fit is true to size, and the material is lightweight, breathable, comfortable, and stretchy which is perfect for casual office wear or everyday use. I like the subtle design details on the pocket and collar, which add contrast and visual interest without being over the top. The shirt feels substantial without being see-through, and the construction is solid with clean stitching and no loose threads or buttons. At the current online price, this shirt is a good value. My only disappointment is that I got a noticeable snag on the right chest after the second wearing; I’m not sure if there’s a way to smooth the threads back out. Despite that, I still recommend it for style, comfort, and performance.

soft breathable shirt
Color: Navycircles, Size: Large, Color: Navycircles, Size: Large
I measure a 33w and 42c. That would indicate that I should be closer to a size medium. But I have received enough summer short sleeve shirts that have a sizing chart that says that I should be a size medium only to find that they would only look good on me if I were built like Adonis. So I ordered a size large. It fits pretty well. I still think it is a little more snug than I would want but that is just my vanity wishing I had a flat gut. It is a bit difficult to read the washing instructions that are printed in silver on the inner collar. The label says it is 87% nylon and 13% spandex. The craftsmanship of the shirt is excellent. The collar has a nice cloth roll covering the seam so there is no chafing on the neck. The inner seams on the sides are double shitched with an interesting taper at the bottom that would only be noticeable if the shirt is not tucked in. The length of the shirt is sufficient that it will not try to pull out on the back and it is stretchy enough that I think if I tuck it in my underwear it will not pull out when riding my bike. I like the pattern. It is like the little dots on a bird feather repeated over and over.

I wonderfully versatile athletically fitting summer polo
Color: Lightbluedot, Size: Small
Don't really have any down sides on this polo. It's lightweight yet surprisingly wind resistant, even on cooler days im not losing all my body heat at the slightest breeze. It feels more like a cotton blend while performing like a polyester with the stretch and drying performance. The fit is very athletic, with just enough room in the chest and shoulders while hugging close to the midsection. This polo is quality both in looks, with the collar holding shape and appearance, the faux chest pocket ups the look of the shirt without being a clunky piece with a pocket that bunches up. Im thrilled with this polo and am buying more colors to have variety with this shirt. Wonderful wonderful value for the money if you're looking for a versatile close fitting shirt without hindering mobility

Great shirt with a couple of very insignificant flaws
Color: Bluedotwhite, Size: Small, Color: Bluedotwhite, Size: Small
Stylish, breathable, great fit, vibrant color, nice attention to detail with the colorway. Check out my photos for a look at the way the pocket colors and fabrics match that of the collar button, and the tiny perforations in the main fabric that allow you to stay cool in this shirt. There are a couple of spots where you can see flaws, but they're not significant enough to me to deduct a star. The flaws are the thread sticking out of the button, and how the collar has a bit of an indentation in it and isn't totally level smooth. It's hard to figure out how to iron the collar without creasing it in a bad location, so this is the way it looks after ironing with my best effort. All in all, as I've found with the Alex Vando brand, I enjoy their polo/golf shirts a lot - the fit, look, pretty much everything.

Comfortable summer wear. Runs a little big and long
Color: Blueoval, Size: Small, Color: Blueoval, Size: Small
This is a very comfortable polo. I can tell from the features that the shirt is pretty much designed for golf. - Very light weight like tees for runners. It is see through if not for the printed pattern. - Definitely breathable, perfect for dry weather region. Will keep you dry throughout the round and does not cling onto the body to inhibit motion. Structure stays crisp throughout the round. - Stretchable, does not restrict motion during golf, sweat or not. - Longer length to stay tuck in. Note: - It runs big overall. The model shown is 6’1” and he is wearing a Medium. Seeing that, I bought a Small even though I normally wear medium. It fits my upper body perfectly with a little room to spare. - It also runs a little long. It will definitely stay tucked in throughout the round. However, it is too long for me to wear it untucked. I am 5’ 8”. Overall I like the shirt’s quality and a reasonable price for a golf shirt. It would have been perfect had it not been a little long for untuck wear.
