Psycho tech

I already have a psycho tech and a new hyper freak which is not as warm and is wearing out already so I bought another psycho tech to store until I need it your new wetsuits have gone backwards especially given the price these days , as a customer for 50 years disappointed with your new options

Steamer to small

The steamer seems pretty good but I have not been able to try it out as it was too small and I have had to return for a refund as this was the only size you had available.

Wetsuit Review O'Neill

Great wetsuit ! They are a good tight fit and do stretch a little with more wearing . Worm as a 5/4 should be! If you want more flexibility go for the Hyper Freak which i have in a 4/3 and this has been good in the warmer winter days . Psycho Tec Hooded i use on the cold winter days ! Hose down and dry in shade will make them last longer .
