These semi-dry wetsuits are perfect for keeping you warm during extended dives and colder conditions. As a Dive Instructor in water averaging 11-19C, myself and my dive students have used these wetsuits for years and highly recommend them. 
 
"THE WORLD'S FAST DRYING DIVE SUIT" - dries in minutes and incredibly warm! Imagine never having to put on a wet, cold dive suit ever again.

Exclusive to Probe Wetsuits, the revolutionary "QUICK-DRY" fleece inner lining not only dries super fast, it's also super warm, super flexible, super comfortable and makes the suit super easy to slide on and off over your skin.

A major warmth advantage of our "QUICK-DRY" fleece inner lining is that it performs similar to wearing a fleece thermal garment under your entire suit. Providing you with extra "built-in" warmth by trapping your core body heat next to your skin.
 
The 7mm iDRY has been fully tested under CE en14225-1 Thermal Performance Classification and is rated as suitable for use in water temperatures of between 10 - 18°C / 50 - 64.4°F
