Pretty damn good Good fit Very cosy I want to surf more
AustraliaJust bought online and size chart was spot on. Wetsuit fits great and is made really well. First O’neill wetty and can assure you won’t be the last
AustraliaReally awesome wetsuit, pretty much no resistance when paddling or stretching. The zipper along the chest is the only downfall as it seems to have been placed in a way which restricts stretch in that entire area... would love a zipperless but only seem to be available on the states.
AustraliaI had issues with the durability of the Hyperfreak product line, although the most flexible on the market the product life is only 14 to 18 months. I have just bought a Psycho One and happy with the extra warmth and its still very flexible. I can only really advise on the product life after 12 months of continuous use but it appears to be more durable.
AustraliaMight be the most comfy steamer I've ever owned, I'm 6'3/80kg and the MT fits me perfectly. Very small complaint, the other day it was 8-9c with light wind and I got a bit cold while waiting for the sets. Not uncomfortably cold or anything, but it's not as warm as steamers I've had in the past. But as I said, this is definitely one of the most comfortable wetty's I've owned. As long as I wasn't still for too long, I stayed nice and warm. Overall I'm happy with it.
Hi Lachlan, thanks for the great review. What you have said makes perfect sense... This wetsuit, the Psycho One is focused on providing very good warmth with plenty of flexibility. The brother of this suit, the Psycho Tech, is more focused on providing ultimate warmth but sacrifices a tiny little of that comfort and maneuverability/flexibility in favor of extra warmth and wind protection. The key difference is the Psycho Tech features a smoothskin on the chest and back of the body, this smoothskin is that shiny type of neoprene that blocks out the wind, but it's less flexible and adds weight. So the Psycho One that you have doesn't have the smoothskin on chest and back and instead has TB3 neoprene, but is the our best all-round top-end cold water wetsuit, however yes on those super windy days, you might feel the wind a little more. On all the other days, you'll appreciate having a suit that is still very warm, but also light and flexible. Both these Psycho wetsuits have 'Firewalls' which are liners inside the suit to trap extra warmth, so they are both warmer than say our Hyperfreak series suits. Hyperfreak series suits lack a firewall but are made of our most flexible neoprene, TB3X. So those are the most flexible suits but not our warmest. There is always a trade-off of warmth Vs flexibility/weight. What you purchased is considered the best balance of everything. Hope that helps you and other customers choosing between styles!
