Sharkskin Titanium 2 Long Sleeve Full Zip (Men's)

The Sharkskin Titanium 2 Long Sleeve Full Zip is a men's thermal dive top built to serve as your main exposure protection in water down to 68° F (20° C). Sharkskin tested the T2 material as equivalent to 5mm neoprene, so it makes sense for warm water reef dives and long snorkel sessions where a thick wetsuit feels like more than you need.

How the Titanium 2 Fabric Keeps You Warm

Titanium 2 starts with Sharkskin's Chillproof material and builds on it in a few ways:

• Titanium nanoparticles embedded in the fabric capture and hold more of your body heat.
• A hollow yarn fleece on the inside traps a thin film of water against your skin and warms it.
• A one-way membrane blocks wind and water from outside while letting moisture from the inner layer wick away.
• The nylon/lycra outer shell has four-way stretch and a water-repellent, abrasion-resistant finish.

Fit and Sizing for Men

Men's sizes run from SML through 5XL. Plan on a snug fit, since the fleece needs contact with your skin to do its job. Between two sizes, the smaller one usually keeps you warmer.

Frequently Asked Questions

Can I wear the Sharkskin Titanium 2 Full Zip without a wetsuit?

Yes. Sharkskin rates the Titanium 2 range as primary exposure protection in water down to 68° F (20° C), so in water at or above that temperature you can wear it on its own.

How warm is Titanium 2 compared to neoprene?

Sharkskin tested Titanium 2 as equivalent to 5mm neoprene for thermal protection, while the four-way stretch outer layer keeps it flexible enough to move freely.

Does the Titanium 2 top help on the surface between dives?

It does. A one-way membrane inside the fabric keeps wind and water out, which reduces the chill of sitting on a boat in wet gear.
