Types of O’Neill Wetsuits

O’Neill spent decades creating the most cutting-edge wetsuits in the market, and the brand offers tons of them to fit all types of athletes from all skill levels and sizes. O’Neill wetsuits come in a wide variety of designs and styles, with some perfect for winter or colder weather while others make suitable summer suits.

Check out your style options when buying O’Neill wetsuits.

Wetsuit Jacket or Vest

When you need minimal insulation, like when you go surfing during warmer months, a wetsuit jacket or vest is the best option. These types of wetsuits are usually thin enough to give your core a little warmth while offering breathability, perfect for warm weather.

You can use a wetsuit jacket or vest by itself during the summer or use it as an extra layer for a full wetsuit during colder weather.

Spring Suits

Spring wetsuits have short legs but have either short or long sleeves. It’s ideal for use when the water temperature goes from warm to chilly one minute, like during spring and autumn. This type of wetsuit provides ample protection from the sun’s damaging UV radiation while keeping the body warm in critical places.

Long John Wetsuits

Long Johns have longer legs than the typical spring wetsuit. It keeps your entire lower body warm against the cold water and air while its sleeveless design gives your arm maximum freedom for swimming or paddling.

Full Wetsuits

A full wetsuit offers protection from the sun, water, and air for your entire body. It can keep you warm and comfortable no matter how cold the water temperature is. This type of wetsuit covers your whole legs and arms, allowing you to stay in the water for a long time. Thinner full wetsuits are available for summer use, while thicker options are essential as a winter wetsuit.

Hooded Full Wetsuits

This type of wetsuit is similar to full wetsuits, only with an addition of a fixed or removable neoprene hood. When surfing or diving in colder water temperature, a hooded wetsuit design keeps your entire body warm and well-insulated, including your ears and head. This type of wetsuit is essential when you are swimming or surfing during the winter season.
