Sarah Says:

This is by far my favorite suit, and worth the money. It's super warm, super flexible, lightweight, and dries quickly. The TechnoButter 3 Neoprene easily makes this the most comfortable suit I've worn because of how stretchy and light it is. It slips on and off easily whether it's wet or dry, and you don't feel like you're wearing 5.5mm of neoprene. The cut is simple and flattering, the fluid seam welds are high-quality and keep this suit water tight, and it's one of the only suits I've felt truly warm in. If you can swing it, get this suit.


One of the best-hooded wetsuits made for the ladies, the O'Neill Women's Psycho Tech 5.5/4 Hooded Wetsuit is better than ever. Including the most advanced heat trapping elements, the Psycho Tech has external fluid seam welds, internal taping in critical areas and quick drying TechnoButter Air Firewall Smoothskin panels in the chest and back to block wind chill and soak up the sun's warmth. The tactical combination of TB3 (TechnoButter 3) neoprene and TechnoButter Firewall deliver maximum maneuverability and a snug, comfortable fit.

Focusing on a pleasant and productive experience, the Psycho Tech is loaded with everything you need for long sessions in anything from chilly, to downright hostile cold water conditions. Wrist and ankle seals, durable knee pads, heavy duty zippers are all part of the package along with a toasty warm two-layer F.U.Z.E chest zip that keeps water from entering at critical points and seams while retaining a relatively generous entry. Fully equipped for performance and warmth, the O'Neill Psycho Tech is simply one of the best, high quality options for women surfers.

I'm 5'4" about 130 lbs, 34 chest, 27 waist, 40 hip, and this suit fits like a glove! Have been in the water a since the end of December and I don't even feel the cold! Learning to surf in the winter has been awesome!

O'Neill Women's Psycho Tech 5.5/4 Hooded Chest Zip Wetsuit Fantastic suit!Review by Andrea Andrea
This is my first front zip and it's worth the trouble to get it on and off ( and it does get easier). Super stretchy, snug, feels light and flexible, haven't shivered once through a long, cold New England winter. Highly recommend.

O'Neill Women's Psycho Tech 5.5/4 Hooded Chest Zip Wetsuit Best Woman's Winter SuitReview by Kelly Kelly
This suit is great. The new thinner technology keeps you warm and allows for so much more mobility than other winter suits. It is a bit tough to get on and off at first but it does get easier. It has put a whole new spin on winter surfing for me and I am so glad I purchased it.

O'Neill Women's Psycho Tech 5.5/4 Hooded Chest Zip Wetsuit Seems greatReview by Joanna Joanna
I just got this suit so I've only used it a handful of times, but so far I love it.
Fits really nicely, seems to be great quality, and is surprisingly stretchy for paddling (no tougher to paddle in than my 4/3 flashbomb).
It is a little bit of a workout to get in/out of, but I think that's to be expected with a suit this thick, and it does get easier every time.
