Technical characteristics:

TECHNOBUTTER 2-NEOPRENE

Has the same properties as TechnoButter neoprene, but with the addition of an inside that is resistant to velcro. Standard on all TechnoButter products with Velcro.

SIMPLE, LIQUID-SEALED SEAM

O'Neill's liquid-sealed outseam is a revolutionary seam construction that covers the outside of a bonded blind-stitched seam with liquid, non-abrasive, high-quality urethane-silicone adhesive that is water-resistant while maintaining maximum flexibility.

DOUBLE SUPERSEAL COLLAR

A pleasantly warm 2-layer design with a soft inside, ample adjustment options and a secure closure. Fully adjustable and waterproof.

CRYPTO KNEE PADS

Extremely durable, extremely stretchable and ergonomically shaped neoprene inserts that have a long service life. The flexible and unique design with an extended knee pad provides extra durability.

SUPER SEAL CUFFS

O'Neill Super Seal cuffs prevent water ingress. The welded seam seals the cuffs and is extremely durable.

OUTER KEY POCKET WITH LOOP

Abrasion-resistant, extremely hard-wearing and ergonomically shaped neoprene insert with a high stretch factor. Placed on the inside of the lower leg. Fluid Seam welds and UltraFlex DS neoprene material make this key pouch extremely robust, easy to use and absolutely secure.

TECHNOBUTTER 2-AIR FIREWALL

Available in single (single lined/ SL) and double lined (double lined/ DL) versions. Has the same properties as TechnoButter but with the advantages of Air Technology. TechnoButter Air Technology is a complex 3D structure of neoprene and trapped air. Think of double-glazed windows, which trap more heat by trapping air. The TechnoButter Firewall interior is 20% lighter and absorbs 30% less water. The result is the warmest, lightest and fastest drying material available.
