O'Neill Women's Slasher Comp Vest


5 reviews
By O'Neill

Our vests are engineered for performance, tested by the greatest athletes on the water, and defy conventional design. O'Neill's NytroLite Foam is more buoyant, lighter by a factor of 3, and provides superior impact protection compared to traditional foam. Using an exclusive nitrogen-expansion process, our Low Density Polyethylene is 10% more buoyant, 15-20% less water absorbent, and 3 times lighter than standard PVC foam.

    Competition Vests are designed to fit skin tight. They are form fitting and will stretch. If you are used to wearing a loose fitting vest, ski and wake vests will feel much different. They are designed NOT to ride up on you while in the water. When you first zip the vest, it will feel very tight, then loosen up once you are in the water.


    What does H2OProShop have to say:

    We love how buoyant O'Neill Comp vests are while not adding any bulk, the Nytrolite foam truly is noticeable right when you jump in the water.  They are comfortable to wear, and impact resistant.  We wouldn't sell anything that we gave a bad review, and O'Neill is on the top of our list for vest design!

    Overall a good vest

    Overall, I am pleased with the look, quality, and performance of this vest. The sizing is slightly off. I have a 36” chest and ordered the large. It stretched out after the first use and is now marginally big.


    Beautiful and lightweight and great customer service!!!

    Comfortable and stylish

    Tailored fit like a big hug. Stylish and unique. Trying it out for outrigger racing in the cooler weather. It is warm for sure.
