O'Neill Women's Reactor 2mm Spring Good suit as expectedReview by debe debe
Fits good, looks good, keeps the chill off. Get a little back neck drip but not such a big deal for a spring suit. Use it for fall/spring surf in Florida.

O'Neill Women's Reactor 2mm Spring Good productReview by Lysa Lysa
I had recently started SUP and wanted to,have my own wetsuit so I didn't have to wear rented ones. The O'Neil Spring wetsuit is perfect for my use. I'm usually a size 4 in clothing; I opted to get a size 6 for the wetsuit as I wanted to have enough room for movement. I prefer a comfortable fit over one that's snug. And the size 6 worked nicely for me.
Packaging and customer service by Cleanline Surf is awesome. With my order, I got some nice freebie items - including some Starburst candy,. : ). I thought that was so cute!
