Best swimmers I've owned for sges
Fit is great. Love the pattern and the fit. Around my bottom is great no crawling up. Slightly tight on shoulders but once in water all good. Very supportive. And im a life saving and play underwater hockey.

These swimmers fit amazingly and I wouldn't go with another brand as these ones stay on perfectly
These swimmers fit amazingly and I wouldn't go with another brand as these ones stay on perfectly throughout my hour and a half swim session.

Garra Jammers
They look good & feel great on. I normally wear 31/32" waist jeans and the 16 was a tight but good fit for me.

Love the xover one piece
I have now purchased 3 x xover one-piece kozii's to have in rotation. They are fantastic, everyone comments on them at the pool as the colours are amazing and fit very complimentary. Tip size up by 2 sizes. Love these kozii's, of course I need a 4th pair now, ha ha
