For a wetsuit, we find that your weight is usually the most important measurement to follow. Height is less critical as a wetsuit will still function well if the legs are a little too long or short. We also suggest going for the smaller size if you are tossing up between two sizes.. most women's returns come back because the wetsuit fitted 'Too large'.
  1. Weight - Jump on the scales to weigh yourself.
  2. Height - Your full body height, measured from the floor to the top if your head.
  3. Bust - Keeping the tape level, measure under your arms around the fullest part of the bust.
  4. Waist - Measure at the narrowest part of the natural waistline with no tension around the tape.

THE ULTIMATE WETSUIT- 4/3 back zip HyperFire

I was shocked on how good it was! I live at Angourie and mainly surf a 2/2 mm long sleeve steamer and 3/2 for mid winter with all front zips. I wanted the 4/3 for J Bay in 2025. I have recently developed a dodgy left shoulder and opted for the back zip . About 2 weeks ago I received the west suit and we had probably our coldest day for winter. Only 19 but with a cold offshore from icy/snowy Glen Innes. The flexibility in the sleeves and shoulder were next level by 3 levels!! It was the easiest wetsuit I have ever put on and the pullover neck seal was a dream to pull over. In the water there were zero leaks and warm. Most of my wetsuits are Nuetral - neither cold or warm. Then 1/2 way through the surf I felt this weird feeling around my kidney regions - they felt WARM -this was a first time . Then I remember it had the 4 mm thick rubber panels - which I had never seen around the kidney regions before - GENIUS! The flexibility during the surf was unparalleled - never felt anything like it !

After the surf removing the wetsuit was a breeze - because of the back zip and flexible panels-normally I find it a nightmare .

As my other wetsuits have limestone impregnated neoprene - I am used to quick drying times of 4x 15 ( 4 sides to dry in the sun) minute - total drying of 1 hour. This wetsuit took4x30 minute with total drying time of 2 hours. Most other wetsuits can take days to dry . This wetsuit has such a variety of new technology panels.

I honestly cannot see how you could…
