Matt Says:
"O'Neill has been making the Hyperfreak series for years and now we finally are able to enjoy this wetsuit in a 4/3 hooded version. This is the stretchiest hooded wetsuit on the market hands down, thanks to the TB3x Neoprene in the shoulders and arms. Internal tapping makes this suit simple yet durable and a great buy for anyone looking for a mid-range 4/3 hooded wetsuit, or just an insanely stretchy suit with a hood. I would recommend this wetsuit for water temps between 50 and 60 degrees Fahrenheit depending on your air temp and personal preference."

I love my 4/3 back zips but this suit beats them all. I haven't been happy with the current seperate hood options so I decided to try this one since I'm wearing the 5/4 version in the winter. I may never buy another back zip again.

REALLY light and flexible
This is for sure the lightest and most flexible 4/3 I have ever worn/ owned especially since it is a 4/3+. I put it on thinking "This thing feels like a 3/2, there's no way its warm enough for PNW water temps." I was wrong. It's super toasty and easy to put on/ take off. Dries quick, seals well, and keeps the shoulder burn to a minimum. For the record, I'm 6'4/ 185 lbs and the LT fits perfectly.

Super Warm
Ordered the hooded O'Neill HyperFreak 4-3 suit. The suit was in perfect condition, no flaws or defects anywhere (the first thing I checked). Super warm, excellent comfort, great suit for cold winter water temperatures.
