Excellent top for the price

"I wear an XL in everything, 6'3" 200lbs, and it fits perfect. It is difficult to get on and off but the fit is exactly how you want it for surfing and other water sports. I replaced my other one I've had for years because it got worn and very stretched out. Super stoked they still make this one!"

Q&A

HI , I always buy hyper freak 1.5 L/S tops, u have been out of this for a long time, was wondering if the Reactor 2 fits the same? had a Reactor before but was a lot shorter then my Hyper freak top. can please let me know if length is same or not. thanks Dean
Hi Dean! For any inquires regarding neoprene top measurements, please feel free to reach out to our wetsuit customer service team by email at info@oneillwetsuits.com
I am looking for a top to wear to swim. Our pool is not heated in winter stays around 60 degrees. Would this work for that or what would you recommend. I want to be able to have arms covered and swim free style or back stroke
Hi Melika! If you don't want a full suit or spring suit, I'd recommend the 1.5mm tops - although I'd probably stay away from the Jacket Tops since those are zip-up and may restrict movement for swimming. The REACTOR-2 1.5MM L/S TOP or the HYPERFREAK 1.5MM LONG SLEEVE TOP (which has more stretch/flexibility it it) are probably your best bet.
