ION Seek Core 5/4 Backzip 2026 Wetsuit

Stay warm and flexible in any season with the Seek Core 5/4 from ION

Looking for a reliable wetsuit for the colder season that offers both warmth and flexibility? Then the new ION Seek Core 5/4 Backzip 2026 is a solid choice. A smart blend of materials and advanced linings keeps you comfortable longer, even when temperatures drop.

What makes this ION wetsuit stand out is the combination of natural rubber with a high-performance inner lining. The neoprene is completely oil-free and made from sustainable materials such as oyster shell powder, soybean oil and eco carbon black. Great for you and the ocean.

Inside, the Seek Core comes with a significant upgrade. The lining has been improved from Hot_Stuff 2.0 to the brand new Hot_Stuff 3.0. This thermal lining feels soft and plush while offering added warmth. Made from recycled nylon and super stretchy, it keeps you toasty without sacrificing freedom of movement.

The comfort layer has also been upgraded. The former Silk_Stuff lining is now replaced with Silk_Stuff 2.0 on the arms and lower legs. This ultra-smooth inner fabric feels soft against your skin yet is tough enough to handle rough sessions. More comfort and more durability in one clean update!

The seams are blind stitched and glued to keep as much water out as possible. Thanks to the Maki_Tape 2.0 elastic neoprene tape at key stress zones, the suit is extra durable and watertight. The backzip makes it super easy to get in and out, even with cold hands.

In short, the ION Seek Core 5/4 Backzip Wetsuit is your reliable go-to for chilly days. Warm, flexible, eco-friendly and ready for action!
