    • Open Water swim Wetsuit
I have used this wetsuit for a 2 mile open water swim in the pacific and other fresh water swims. Fit is excellent - I got MT and I am 6'+ and 188 lbs. The only issue was when I did not do the velcro around the neck correctly and I got a rash, but this was my fault. Corrected when I used the next time. Never any rash on arms, legs or anywhere else for long swims. ... show more

    • Excellent wetsuit!
Arrived later than promised and in no way a reflection of the seller. The wetsuit was perfect and worth the wait.

    • Flexible wetsuit with an easy back zipper.
My grandson used this on freezing and hot days in our cold northern lake. It dried quickly before the next swim. It fit well.

    • Great fit MT
I’m 6’ 1”, 178lbs, 42” inch chest. Based on the reviews I was worried it wouldn’t fit right. I’ve never owned an O’Neill before and used to be heavier in a LT by Xcel. The chart was on the money, it fit perfect and not restricted at all. A new wetsuit is always going to be tight at first, gotta break it in. It needs to be tight in order to work, otherwise it’ll slow you down. If you feel completely suffocated squeezing in, yeah then you need a size up. Use the chart, it works. Great purchase! ... show more

    • velcro fades off
The reason for the two stars is that it has the potential of being a good suit. However, the velcro faded off after just using the suit a few times. This gets annoying since the zipper gets undone when in the water. Hoping to get a replacement or a fix.
