DETAILED DESCRIPTION
The Element by ION
ION created the Element for riders who love being in the water and need straightforward gear to have a great time. This wetsuit is flexible and elastic. It is also robust, incorporating several of the collection's most technical details. The ION Element 4/3 Overknee LS Back Zip men's 2023 is the 4/3 version with long sleeves and overknee legs. It has a back zip. This 2023 vintage is now end-of-life at ION, but you can find the current Element available online alongside it.
Linings
Hot_Stuff 2.0, ION's most elastic thermal lining, covers the back and torso, delivering warmth, flexibility, and comfort. Silk_Stuff on the chest and shoulders ensures a comfortable fit. On the arms, it provides excellent elasticity for your shoulders.
Robustness
The nylon exterior features Supra_Tex protection. Critical seams are reinforced with either glued seams or flatlock stitching, and all stress points are strengthened. Plus, small padding protects your shins.
For what conditions
A 4/3 wetsuit is perfect for spring and autumn sessions on the Atlantic coast; for winter, you'll want a 5/4. The overknee leg design keeps your knees free when the water starts to warm up. Available in sizes 46/XS to 56/XXL.

FAQ - ION ELEMENT 4/3 OVERKNEE LS BACK ZIP MEN 2023
This wetsuit is for the kiter, wingfoiler, or surfer who wants a flexible, durable, no-frills wetsuit with a back zip. A 4/3 is ideal for spring and autumn on the Atlantic coast; for winter, you'll need a 5/4. The overknee leg design keeps your knees free as the water warms up.
The ION size guide further up the page provides height and weight for each size, along with chest circumference. A wetsuit should fit snugly when dry, with no air creases. If you're between sizes, give us a call.
They share the same range and spirit: flexibility and elasticity, which makes them robust. The 2023 model is a previous vintage, now end-of-line at ION. You can find the Element from the current collection available online alongside it.
After every session, rinse your wetsuit inside out with fresh water. Hang it on a wide hanger in the shade to dry. Never dry it in direct sunlight or on a radiator, and never fold it wet in a bag. Always close the zip before hanging, and rinse the pull tab thoroughly; sand is the quickest way to wear out a zip.
We're a dedicated shop for Kite and Wing, as well as Surf. We are located in Pornichet, right on the Atlantic coast, and we're out on the water all year long. We don't just sell ION wetsuits; we wear them ourselves. If you're unsure about the right size or thickness, give us a call or swing by the shop!
