Gul Response FX 5/4mm Chest Zip Men's Wetsuit

The Gul Response FX 5/4mm neoprene steamer wetsuit takes the DNA from Gul' core Response collection and morphs it into a high performance comp-level wetsuit - think of it as a 'pimped' up Gul Response.

This Gul Reponse FX features Aqua Barrier Chest Zip Entry, combining 5mm and 4mm thick double lined neoprene for superb thermal protection and flexibility. Constructed with glued and blindstitched seams and all over X-Flex super stretch and thermal linings, giving you over 150% stretch. The Response FX wetsuit ticks more than just the required basics in this an entry level Chest Zip 5/4mm wetsuit. Incorporating critical waterproof taping helping to virtually eliminate flushing and so aiding warmth retention.

Gul's Aqua Barrier Chest Zip entry system wetsuit helps ensure minimal water ingress around the neck while improving comfort and flexibility. Removing the usual rear zip entry means there's less panelling, less stitching, less opportunity for water ingress and greater freedom of movement.

Combining Gul's 150% stretch neoprene and thermal linings the Response FX morphs into a higher level performance with improved thermal properties and greater flexibility resulting in a enhanced freedom of movement. 

Typically a 5/4mm neoprene wetsuit is considered a Winter wetsuit although depending on which activity you may wish to wear the wetsuit for and in what conditions this wetsuit could be suitable for year-round use.

The Gul Response range of wetsuits have consistently been a popular choice of multi-sport steamer wetsuits that could span four seasons providing great value and performance. A quality Steamer wetsuit from Gul who have been at the forefront of wetsuit design in the UK for some 50 years.

On an environmental note Gul use non-petroleum based neoprene in the making of the Gul Response wetsuit. These wetsuits arrive packaged in bioplastic - containing cassava, vegetable oil and organic resins. The material is biodegradable and compostable, breaking down over a period of months on land or at sea but dissolves instantly in hot water
