Chillproof vs T2 Titanium: Which Sharkskin Range Is Right for You?
Once you have decided you want Sharkskin thermal wear rather than a neoprene wetsuit, the next question is which range: Chillproof or T2 Titanium. Both are neoprene-free thermal water-wear distributed by Sharkskin Europe across the continent, and both keep you warmer in and out of the water. The difference is what conditions and use each one is built for.
Chillproof: the everyday, multi-sport range
Chillproof is the more versatile of the two ranges. It is designed to be worn on its own in warmer and temperate water, and it works well across diving, snorkelling, surf, kite, SUP and swimming, useful if you move between sports in the same session or the same trip. It is the range most people reach for as a single, everyday piece of thermal kit.
T2 Titanium: the warmer, more technical range
T2 Titanium is Sharkskin's warmer range, built with a titanium-based lining designed to reflect body heat back to you rather than let it escape. It is aimed at colder water, repeat dives, and longer sessions where you need more warmth than a single everyday layer gives you. It is also the range most divers choose as a base layer under a wetsuit or drysuit when the water turns properly cold.
How to choose: by conditions
- Warm to temperate water, worn alone: Chillproof is usually the better fit - enough warmth without overheating, and flexible enough to move between sports.
- Cooler water, worn alone: T2 Titanium gives more warmth for conditions where Chillproof on its own would leave you cold.
- Cold water, as a base layer under a wetsuit or drysuit: T2 Titanium is built for this, adding warmth without adding meaningful bulk under your exposure suit.
- Repeat dives through the day: T2 Titanium's extra warmth matters more as your body heat depletes dive after dive.
- Multi-sport use across a trip (dive one day, surf or paddle the next): Chillproof's versatility tends to win out.
How to choose: by use
If you are a school or rental fleet outfitting students or renters for a range of conditions, Chillproof's versatility across sports and conditions tends to make it the easier single range to stock. If your customers or your own diving skews toward colder water or serious repeat-dive days, T2 Titanium is worth carrying or wearing alongside it as the warmer option.
Plenty of divers end up owning both: Chillproof for warmer days and multi-sport use, T2 Titanium for the colder days and as a layer under an exposure suit.
At a glance
| Chillproof | T2 Titanium | |
|---|---|---|
| Best for | Warm to temperate water, multi-sport | Cooler water, repeat dives, layering |
| Worn alone or as a layer | Mostly worn alone | Alone or under a wetsuit/drysuit |
| Warmth level | Everyday warmth | Sharkskin's warmer range |
| Versatility across sports | Dive, surf, kite, SUP, snorkel, swim | Same, with a focus on colder conditions |
When neither is quite right
In genuinely cold water, neither range replaces a proper wetsuit or drysuit as your outer exposure protection - they are designed to work with one, not instead of one. If your diving is mostly cold water with a drysuit already, think of T2 Titanium as your base layer rather than your main defence against the cold.

Still not sure?
If you are weighing up thermal wear against your current wetsuit setup more generally, our guide on how to stay warm scuba diving covers the layering approach in more detail. Otherwise, think about the water temperature you dive in most, whether you will wear it alone or under a suit, and how many sports you want one piece of kit to cover.
A useful rule of thumb: if you are only ever buying one Sharkskin piece and you are not sure, Chillproof is the safer everyday choice for most people. Step up to T2 Titanium once you know your diving regularly pushes into cooler water, longer sessions, or repeat dives where the extra warmth earns its place in your kit bag.
