THERMAL FLEX FEATURES

Warmer than Lycra / Spandex and traditional Jammers

Thermal-Flex offers the flexibility of lycra but with significantly more warmth to keep you comfortable in cooler water. Using Smart Skin FIR technology instead of adding thickness and bulk, Sharkskin delivers the perfect blend of thermal protection and maximum flexibility.

Revolutionizing Swimming

The new Sharkskin Thermal Flex range is a game-changer for swimming. It combines thermal insulation, FIR technology, superior flexibility, UPF50+ sun protection, and high-visibility colour options for ocean safety.

On the surface, it shields you from wind and cold without restricting movement, while its high breathability ensures optimal thermoregulation. The Hydro-Lock water repellent treatment is next level and adds more durability to the garment by protecting the threads plus reduces water friction dramatically to allow you to swim faster. The FIR active recovery technology combined with body mapping compression fit helps you to recover while you are swimming. Thermal Flex will revolutionise the way swimmers recover and stay warm and protected in the water.

A Smarter Alternative to Wetsuits

Until now, swimmers had to choose between traditional jammers, which provide no warmth, or a bulky and buoyant wetsuit alternative that can restrict movement. Thermal Flex changes the game by merging advanced fabric technology with thoughtful design. Developed with feedback from Sharkskin ambassadors worldwide, this revolutionary range offers ocean swimmers, surfers, and all active water sports enthusiasts maximum flexibility while taking the chill off the water for a more comfortable and enjoyable experience.

Enhanced Surfing Performance

Surfers benefit from the extra warmth and water-shedding properties of Thermal Flex, making it far superior to traditional jammers especially when sitting on a board exposed to the wind. Soft-stitch panels ensure unrestricted, friction-free movement.

Optimal Comfort for Snorkelling & Diving

Thermal Flex is designed to keep you warm and comfortable when water and air temperatures are cooler, so you can fully enjoy your underwater adventures without getting chilled. When it's too cold for a Sharkskin Rapid Dry but not cold enough for the Sharkskin Chillproof range, T2 Chillproof range, or a wetsuit, then Sharkskin Thermal Flex is the perfect solution.

Smart Skin technology is showcased in this handcrafted garment made with fabric that integrates ultra high-density compression material with Hydro-Lock and FIR technology. Thermal Flex garments provide enhanced insulation without extra bulk to ensure the best body thermoregulation—so you can focus on your underwater explorations with ease.

Support for Recovery & Training

Stay active while training at a slower pace! Those recovering from injuries or needing extra comfort will appreciate how easily Thermal Flex can be put on and taken off - all thanks to its super-flexible design. For individuals focused on health and wellness, Thermal-Flex’s inbuilt FIR technology supports metabolism, aiding recovery and repair even during training sessions.

Discover the Power of Far Infrared (FIR) Technology

Sharkskin Thermal Flex takes innovation to the next level with its advanced Hydrophobic Nanotech Compression fabric. This high-performance material is designed to keep you warmer, speed up recovery, and move effortlessly with your body.

What makes it special? The fabric is slightly heavier to provide extra insulation while still offering incredible flexibility, so you never feel restricted. Plus, with Hydro-Lock technology, it repels water and resists absorption—even when fully submerged—keeping you drier and more comfortable for longer.

But the real game-changer is the Far Infrared (FIR) Nano-technology, inspired by Sharkskin’s R-Series Compression range. This next-level tech delivers three key benefits:

1. Enhanced Warmth – Your body heat is reflected back to you, keeping you cozy in cold conditions.

2. Performance & Recovery Boost – FIR radiation is known for improving circulation, reducing muscle fatigue, and speeding up recovery.

3. Built-in Protection – A permanent antimicrobial effect keeps your gear fresher for longer.

Experience the unbeatable combination of warmth, flexibility, and recovery benefits with Sharkskin Thermal Flex, engineered for those who push their limits.
