Benefits of the O’Neill Wetsuit

O’Neill wetsuits have been a top choice for surfers for many years now, largely because of the amazing fit that they offer. Jack O’Neill started the brand in 1952 when the creator’s passion for surfing inspired the very first surf shop in Santa Cruz and the subsequent development of amazing surfing apparel.

O’Neill is credited with making the very first wetsuit, and the high level of quality and innovation continues to be prevalent in each wetsuit that goes on the market.

Consider the following benefits of O’Neill wetsuits;

  • The entry-level price range makes it an affordable option for all surfers
  • Variety of thickness levels to suit every season (5:4 winter, 4:3 spring/fall, and 3:2 summer)
  • Quality design and material for long-lasting enjoyment

How to Fit a Wetsuit

The most important part about fitting a wetsuit is referencing the brand’s size chart. Once you’ve got your size, you need to make sure that it fits snugly, like a second skin. Make sure that you can still move comfortably and move your arms in a paddling motion. If there’s space, practice a pop-up too!

Keep in mind that the wetsuit will become more comfortable and loosen slightly once in the water.

The sleeves of a full-length wetsuit should come to your wrist bone and the legs should end at your ankle bone. Ideally, there will be no gaps or rolls of neoprene.

When a wetsuit fits well, then you should have a full range of motion and trust that the material will remain durable for a decent amount of time. When a wetsuit is too small, then you limit your flexibility and put a lot of stress on the seam. When a wetsuit is too big, then it can reduce your warmth and make you feel uncomfortable in the water, cutting your surf short.

In addition to a good fit, you should consider the following three aspects;

  • Warmth
  • Durability
  • Flexibility
