Thermal Flex Socks
Lightweight warmth. Fast drying. Built for wet environments.
Thermal Flex Socks are designed for situations where your feet will get wet — and still need to stay warm, comfortable, and unrestricted. Made from ultra‑thin, high‑density stretch Lycra, they feature a DWR (Durable Water Repellent) finish and titanium‑infused fibres that generate Far Infrared (FIR) thermo‑regulation.
The result? A lightweight sock that delivers surprising warmth, dries fast, and keeps your feet comfortable — even after repeated soaking.
Why Thermal Flex Works
🔥 Warmth Without Overheating
Titanium nano‑particles reflect your body’s natural heat back toward the skin, maintaining consistent warmth without trapping excess heat. Your feet stay warm, regulated, and sweat‑free.
💧 Water Repellent & Fast Drying
The DWR treatment causes water to bead and shed from the fabric. After full immersion, Thermal Flex Socks dry rapidly — perfect for multi‑session water sports or long work days in wet conditions.
🧦 Thin, Stretchy & High-Density
Unlike bulky thermal socks, Thermal Flex is thin, smooth, and extremely elastic. Ideal for wearing:
- Under water shoes
- Inside dive or snorkel fins
- Inside neoprene boots
- Under wetsuits for easier entry & reduced friction
No pressure points. No restriction. Just flexible, all‑day comfort.
💨 FIR Compression for Circulation & Recovery
Gentle compression combined with FIR technology helps support:
- Improved circulation
- Reduced fatigue
- Faster recovery
Great for both in‑water performance and everyday wear.
Designed for Water. Useful Everywhere.
Perfect for:
- Snorkelling & diving
- Surfing, paddling & kayaking
- Wearing under neoprene boots for added warmth
- Easier wetsuit entry
- Cold, wet work environments
- Travel, recovery, and daily warmth
Engineered for water sports — loved as an all‑purpose warm sock.

Warmth Without Overheating
Far Infrared energy reflects your body’s natural heat back toward the skin, creating consistent warmth without trapping excess heat. Your feet stay warm, comfortable, and regulated — not sweaty or stifled.

The DWR treatment causes water to bead and shed from the fabric. Even after full immersion, Thermal Flex Socks dry exceptionally fast, making them ideal for multi-session or all-day use.
Thin, Stretchy & High-Density
Unlike bulky thermal socks, Thermal Flex is thin and highly elastic, allowing it to fit comfortably:
- Under water shoes
- Inside dive or snorkel fins
- Inside neoprene boots
- Under wetsuits to ease entry and reduce friction
No pressure points. No restriction. Just smooth, flexible comfort.
FIR Compression for Circulation & Recovery
The combination of gentle compression and Far Infrared technology has been shown to support:
- Improved circulation
- Reduced fatigue
- Faster recovery
This makes Thermal Flex Socks as useful out of the water as they are in it.
Ideal for:
- Snorkelling & diving
- Surfing, paddling & kayaking

At SHARKSKIN, we deeply care about the environment, as many of us are avid scuba divers and natural world enthusiasts. Our commitment to sustainability is demonstrated through five key company initiatives.
- Solar Powered
We are pleased to announce Sharkskin’s new building is 100% solar powered. - Environmental Manufacturing
Sharkskin manufactures in its own factory, allowing us to strictly control waste and efficiency. We pack our orders effectively to reduce freight and waste, and we use cutting-edge technology to minimize material waste throughout the manufacturing process. - Biodegradable Packaging
We have transitioned to biodegradable packaging. Currently, 95% of our range uses this packaging, with a goal to reach 100% soon. All newly manufactured items will be packed in the new biodegradable bags, while items in stock will remain in existing packaging. - Australian Made
We are proud to announce that we have been accredited to use the official Australian made Logo. The official website states, “The famous ‘Australian Made, Australian Grown’ (AMAG) logo is the true mark of Aussie authenticity. It’s Australia’s most trusted, most recognised and widely used country of origin symbol, and it’s underpinned by a third-party accreditation system, which ensures, products that carry the logo are genuinely Australian”.
95% of our range is proudly Australian-made. Products that do not feature the "Australian Made" logo below the "buy now" button are not manufactured in Australia. - Built to Last
We believe in creating quality gear that stands the test of time and the harsh Australian conditions. This not only results in a better product but also keeps items out of landfills, reducing waste and environmental impact for the future.
