Winter Wetsuit Technology: Seams

The Winter Wetsuit market is constantly evolving and developing with brands bringing out new technology season on season and many brands using similar technology in different areas and calling it different things. Here at Shore we decided to give a quick run down of the varying different technologies what they mean for you in the water. In this addition of the series we look closely at the Super Seam Weld or Powerseam seen on a lot of the high end winter suits.


Super Seam Weld, Powerseam Weld


The latest in seam technology this is the evolution of many years of wetsuit development and is aimed squarely at the top end of the market. It features a slimmed down version of the classic fluid seam weld technology, which was used heavily in all O’Neill top end suits. With this technology if the suit uses the super seam weld on both sides of the suit the total thickness needs to be 8mm between both external and internal. A lot of companies have experimented with the thickness and it has been proven than a 3/4mm external and 4/5mm internal thickness gives the best option for longevity and warmth. O’Neill primarily use this double sided super seam weld in there top end suits such as the O'Neill Psychofreak and O'Neill Psycho 3.


XCEL, Cskins and Billabong go down a slightly different route. XCEL and CSkins both go for the powerseam however they put this only externally on the suit and internally tape the inside. This tape is called a fusion tape from Xcel wetsuits or a powertape from CSkins they both do a similar great job in holding the seam tight together. With a average of 3 mm of powerseam externally throughout the XCEL Drylock and CSkins Hotwired the suits are super warm and with the tape can sometimes last a bit longer than double powerseam both internally and externally although using this tape does compromise the flexibility slightly.


Billabong in their Billabong Xero Pro again offer a slightly different take on the Powerseam. Only using this internally throughout the wetsuit. With a standard double over lock stitch externally and then internally throughout around 70% of the suit use the powerseam weld. This offers a slightly different take on the use of the seam technology and does prove to be very effective and helps in keeping costs down on the suit making the wetsuit seam technology more affordable.
