In this post you can find information about De Soto First Wave wetsuits – description and key features from the manufacturer website plus added reviews and experiences from users. The manufacturer claims that the two-piece design of the T1 wetsuits offer more comfort and less restriction than a one-piece.

The manufacturer De Soto description of First Wave: “This is the fastest wetsuit that money can buy. We use our new GreenGoma™ #9 Rubber with Slick Composite Skin. This new rubber is extremely flexible and buoyant; the best money can buy!. For more than a decade, no other company has been able to produce a wetsuit as fast as the First Wave Pullover  or the First Wave Concept 5 and First Wave Bibjohn. We continue to give you the ultimate wetsuit.”

 All T1 models are sold as separates for a customized and personal fit. With up to seven sizes of tops and bottoms, you have 49 possible size combinations from which to choose. T1 First Wave Concept 5 and T1 First Wave Pullovers are identical with the exception of the sleeve thickness. Concept 5 has 5 mm sleeves and the First Wave has 2mm sleeves. The Bibjohn is 5mm thick from the oval ankle openings up to the crotch and up the sides of the hips. From that seam up, the Bibjohn is 2mm thick. 

First Wave wetsuit is an elite/pro performance level wetsuit for men and women. Standart manufacturer price T1 First Wave Concept 5 Pullovers $440 (EUR 374), T1 First Wave Pullovers $370 (EUR 314) and Bibjohn $440 (EUR 374) .

  • BIO-STROKE design puts your arms into a forward rotated shoulder position for a more efficient swim stroke

Reviews about First Wave Wetsuit

Here I gathered different reviews about De Soto First Wave wetsuit from different sources. I hope it will help you form your impression about the De Soto First Wave wetsuit.

Review on the “Slowtwitch” website, dated February 10, 2017.
Short summary: Who should buy this wetsuit? Are you odd shaped? Do you have a much bigger upper body than lower body or vice versa? Do you have a very long torso? Do you always have trouble getting your wetsuits to fit? Or putting wetsuits on? Can you never find a wetsuit with a comfortable neck? Here you go. Older people who have limited shoulder mobility or strength like this wetsuit. Those who find that wetsuits are very chest-constricting like this wetsuit. These are the problems the 2-piece wetsuit uniquely solves.

  1. Hi, I purchased a De Soto 2 piece wet suit from you about 10 years ago. I found it to be the perfect wetsuit. I have experimented with different suits and I still revert back to my old De Soto when I have a tough swim to do. I now need to replace the top. Is there anyplace in Ireland I can buy this product ? What are my options?
    Regards Paul Timlin

    1. Hello Paul!

      Thanks for sharing your experience. I don’t know exact sellers in Irland, but my suggestion would be to contact the Manufacturer De Soto and ask them.
      Would appritiate if you could share afterwards the sellers in Irland – it could help others who are on the search!
