Beautiful fabric
Beautiful fabric and fit. Feels really snug on. Sizing runs small - I'm a size 10 in all other clothing and swimwear.

Fab colour. Great hold for diving.
Love it! Has kept its hold and I took it with me to compete in Croatia. Colour really pops out against the Adriatic backdrop.

Sizing note
I usually wear a 10 in the Elite bind in other fabrics. I opted to size up to a 12 for the CT fabric, but I didn't really need to. It was slightly tighter than the other fabric but I would have been fine to stick with the 10. I prefer a tight fit. Ill be getting a 10 next time. Awesome suit, love it.

I love my Frankii thermal rashie
I love my Frankii thermal rashie. It is much warmer than my normal rashie as the water in my area is down to 14 degrees at present and it will probably get colder.

I love this thermal rashie
I love this thermal rashie. It gives me full movement and extra protection from the cold in the water and from the wind out of the water.
