Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.036". World Products Man-o-War Block. 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.

Really snug, but not uncomfortable
Size: Large, Color: Black
I don't know why these were so much tighter than all the other UA socks I've bought over the years. Not uncomfortable, just really tight when putting them on.

Leg part is TIGHT
Size: X-Large, Color: Black
I am a size 15, and the foot portion is comfortable enough, but the fit of the leg portion is so exceedingly tight that I can't wear them for long, which makes them worthless. I would return them if I didn't already toss the packaging.

Post-COVID Sock Hunt: Finally a Win
Size: Medium, Color: (001) Black / Black / White
Ever since COVID, I haven’t been able to find a pair of socks that hold up for more than a few months. Brands like UA, Adidas, and others seem to have cut corners—likely in response to inflation—by downgrading materials and labor rather than raising prices. The result? Socks that wear thin, rip easily, or lose shape fast. These, however, have been a pleasant surprise. I’ve been wearing them for a few weeks and so far, they’re holding strong. You can tell some cost-saving measures were still made—certain areas feel slightly thinner—but overall, the construction is solid. A key win: they stay on. These are ankle socks (not “no-shows”), and they hug the ankle securely. That’s a huge plus in a world where most post-COVID no-shows slide off halfway through the day. We may never get back to the pre-COVID quality standards without paying a premium, but for now, these are a reliable choice. Ratings: • No slipping: 10/10 • Price: 7/10 • Durability (so far): No pilling or loose threads — promising start.
