KEY INFORMATION
ION SEEK AMP 6/5 BACK ZIP MEN'S 2025 - 6/5 mm cold-weather fullsuit
What we like
- Hot_Stuff 2.0 in the front, Plasma_Plush 2.0 in the back: A very flexible, quick-drying thermal lining covers the front, while a soft, fast-drying fabric in the back protects against cold wind.
- Silk_Stuff on the shoulders and arms: This thin, silky textile is strategically placed where you move most, ensuring unrestricted paddling, pumping, and holding the bar without your wetsuit pulling.
- Recycled Max_Flex: Covering the chest, shoulders, and neck, the Max_Flex outer lining delivers 30% more flexibility, according to ION.
- I_Foam Neoprene: ION chose this low-density foam, infused with oyster shell powder, for its insulation.
- Glued and taped seams: These are blind-stitched, with flexible tape on the entire interior. You'll find reinforced stress points and fused edges at the arms and legs.
- Back zip and Novaskin in the back: The back zip makes for quick, unassisted entry and exit, while the Novaskin fabric in the back effectively blocks cold wind.

DETAILED DESCRIPTION
The 2025 edition of the Amp series
The ION Seek Amp 6/5 Back Zip men's 2025 is the 6/5 back zip version from the Seek Amp series in the 2025 winter collection, ION's most elastic series. While the 2027 vintage is also available, the 2025 model stands out with its specific linings: Hot_Stuff 2.0 on the front, Plasma_Plush 2.0 on the back with a windproof Novaskin textile, and Silk_Stuff on the shoulders and arms. This model is currently at the end of its production run at ION.
Elasticity: Max_Flex, Silk_Stuff, I_Foam
The recycled Max_Flex outer lining covers the chest and shoulders. It also covers the neck. ION states it provides 30% more flexibility and quick-drying properties. Inside, the Silk_Stuff on the shoulders and arms allows for free movement. Beneath these linings, the low-density I_Foam neoprene contains oyster shell powder, a filler ION uses for insulation. The shoulders are without a seam, and the number of panels is reduced.
Back zip, watertightness, and seams
Entry is via the back zip, a design that allows for quick, unassisted donning and doffing, keeping the chest panel intact. Silicone prints on the arms and legs minimize water entry. The seams are glued and blind-stitched, reinforced with a flexible tape across the entire interior, and feature strengthened stress points. The arm and leg edges are fused. You'll find thin padding on the shins, along with reinforced drainage holes and separate straps on the legs.
For what conditions
This is the warmest of the Seek Amp back zip models, perfect for the coldest winter waters and extended sessions. Pair it with a hood and boots for ultimate warmth. Gloves are also recommended. When the water temperatures rise, the Seek Amp 5/4 Back Zip will be sufficient. It's available in ten sizes, from 46/XS to 56/XXL, including short cuts 25/MS to 28/XXLS, which offer a wider chest and shorter legs.

FAQ - ION SEEK AMP 6/5 BACK ZIP MEN'S 2025
This fullsuit is designed for riders who hit the Atlantic coast in the depths of winter, enjoy long sessions, and prefer a back zip they can easily close themselves.
They are the same series, with the same cut and recycled Max_Flex. The 2027 has different inner lining, with Graphene_Plush 2.0 and Hot_Stuff 2.0 throughout the body, and recycled Eco_Stretch. It also adds the Water_Gate panel behind the back zip. The 2025 keeps Hot_Stuff 2.0 in the front, Plasma_Plush 2.0, and Novaskin in the back. This is a proven winter wetsuit, now an end-of-series item at ION.
The ION size guide, located higher on this page, provides detailed information on height and weight, as well as chest circumference for each size. Our short cuts, ranging from 25/MS to 28/XXLS, are designed with a wider torso and shorter legs. Remember, a wetsuit should fit snugly when dry, without any air pockets. If you find yourself between sizes, don't hesitate to give us a call for personalized advice.
Rinse it with fresh water after every session. Turn it inside out and dry it in the shade on a wide hanger. Never dry it in the sun or on a radiator. Never fold it wet in a bag. Close the back zip before hanging it, and rinse the zipper pull with the rest. Sand in a zip is what wears it out.
We are a Kite, Wing, and Surf shop in Pornichet, on the Atlantic coast. We ride all year in water that drops below ten degrees in February. We wear ION wetsuits before we sell them. If you have a doubt about the size or hesitate between two thickness options, call us or visit the shop.
