Wetsuit Construction and material types

To help you understand all the technical ins and outs of wet suits we've put together some explanations of the different materials used in wetsuit construction and the various ways of making the different types of wetsuits that you may come across.

Overlock Stitching
Overlock stitching is the LEAST EXPENSIVE and least effective form of wetsuit stitching. The Two edges of neoprene are rolled together with stitching lightly around them. This forms a ridge inside the wet suit that is both uncomfortable and it also allows water to penetrate the seam.

This type of stitch can generally only be used on neoprene up to 3mm thick and is therefore only really suitable for summer conditions.

Lomo Watersport do not use overlock stitching on any of our wet suits.

Flatlock stitching
Achieved by lapping the neoprene together, this creates a FLAT, COMFORTABLE SEAM but it also allows water to penetrate slightly.
Only suitable for Wetsuits up to 3mm thick and summer conditions.
Flatlock is identified by a band of interlocked thread on both sides of the suit, sometimes in contrasting thread colour for visual effect.

Flatlock stitching is used on our Summer range of wetsuits.

Blind Stitching.
Produced by gluing and then butting together the two adjoining pieces of neoprene, followed by stitching that does not penetrate through to the other side of the neoprene. This is a watertight method of construction and is also the most comfortable option, most winter Wetsuits should be made this way.

Lomo Watersport use blind stitching on our winter wetsuits and often used double blind stitching and gluing of seams to further strengthen and seal our wetsuit seams.


Nylon 2 Neoprene
This is neoprene rubber with Nylon bonded to both the inside and outside of the material. This increases the durability of the Neoprene.

Smoothskin Neoprene
This has no coating on it and is used for internal ankle and cuff seals.

Finemesh Neoprene
This is used on the chest and back panels of our winter wet suits to reduce the effects of wind-chill. Wind-chill is normally caused by the evaporation of the small layer of water held on the outer skin of Nylon covered Neoprene.

3mm Neoprene
This thickness is suitable for Summer wet suits.

5mm Neoprene
This thickness is suitable for Winter wetsuits
