AustraliaGreat wetsuit
Flexible, warm, comfortable. Cant ask for much more.
AustraliaIts ok
I've been buying wetsuits since the late 70s this is my first O'Neill purchase,I found the overall fit really comfortable and flexible.entering the water and first duckdive there was no water entry or flushing.however when falling or impacting the water I found the neck seal would allow a fair bit of water in.overall I really like the suit but on the coldest of days the flushing would lessen my time in the water.
