Women's O'Neill 5.5/4 Psycho Tech Wetsuit Review

As long as I live here on the Oregon Coast, I hope to always have a Psycho Tech! 

Over the last five years, I’ve used two O’Neill Psycho Tech wetsuits from Moment Surf Co and I couldn’t be happier with their quality. For most of these five years, I’ve had a second lesser-quality suit that I rotate in whenever surfing many days in a row, which I’m sure has helped the Psycho Techs last as long as they did. That and I do generally take good care of my wetsuits - I always rinse with fresh water unless I’m on a camping trip, turn right side out after a day of drying, etc. But I’m definitely guilty of sometimes leaving them in the sun to dry.

Compared to the other wetsuits I’ve tried over the years, the Psycho Tech is not only warmer but also more flexible. Paddling feels unrestricted! Getting the wetsuit on and off does not feel like a major battle. I will say that I haven’t lived anywhere else since I started surfing, nor have I taken extensive surf trips to warm water spots, so wearing a 5/4 suit is just totally normal in my experience. For someone new to cold water surfing, this wetsuit might still feel like a burden. But I can say that compared to other wetsuits of similar thickness, the Psycho Tech is amazing and there’s no question that I will get it again when the need arises. Obviously it’s pricey compared to some other brands, but it lasts so much longer that it more than covers the price difference of having to buy a new suit every year. And then of course there’s the important bonus of creating less waste.

In general I’m someone who tends to be more sensitive to cold than those around me, but if anything I’ve had the opposite experience with this suit. It’s lovely to just put the hood down to cool off and refresh. Speaking of the hood, I have a lot of hair and it somehow all gets under there no problem.

One of the two Psycho Techs I’ve had, I sent in for a warranty repair and that went smoothly. I don’t remember now how long it took but O’Neill replaced both arms completely, as my elbows had worn the suit super thin.

Sizing

As far as sizing goes, I’m 5’6 and weigh around 140lbs, and both the 8 and 8T fit me well. Fun fact: when I was pregnant a couple of years ago, I wore a Psycho Tech surfing into my 7th month of pregnancy. The suit was able to stretch no problem.

Both cheers of support and loud laughter were heard throughout Pacific City this past weekend as surfers and spectators gathered on the beach to root on the participants in the annual Cape Kiwanda Longboard Classic. This year marks the 25th running of the beloved community event.
Started in 1998 by Bob and Michelle Ledbetter, the contest has grown to become a staple of the NW surf community. It not only attracts surfers throughout Oregon, but this year saw people from Canada, California, Washington and even Hawaii make the pilgrimage.
Welcome to the team Justin Buford! Justin has been a part of the shop since we opened in 2010. He was a true local grom who would spend his days skateboarding in our parking lot and washing rental wetsuits when he wasn’t in school. His family lived just up the street and his step-dad is one of the best surfers in town. His brother-in-law comes from the legendary South County Surf family the Ledbetters. Surfing is who and what Justin is, it’s in his blood. 
It felt a lot like home, Ireland. I suppose in a bizarre way it is, as my ancestors planted their roots in county Sligo on the North West coast of the country in the early 1700's after immigrating from Scotland. Ireland has been at the top of my travel list since long before I found out there was surf there. I formed images in my head of what the landscape would look like from seeing pictures, videos and hearing stories of infamous rocky basalt point breaks and shallow heaving slabs. Every image I had crafted fell short in comparison to seeing it all in person for the first time.
