I really love the colours in this swimsuit! And I also love that they are lined in black too - I feel its supports the bold colours better. They feel strong and its comfortable in the water.

Great. Love it. Looks good fits well. Went with a size 14 normally a 12 good choice.

love them. I feel very free in the water doing my laps during winter

Fantastic. I wear a 12 in jeans and got a 12 in the thermal pants. They fit good and I probably could have even got a 10. So if you are in between sizes, choose down. I also wore these under jeans when I was at a cold sport tournament (3 degrees!) and they worked so good as outdoor thermals too! They are super comfy and I’ve been recommending them to all my surf club ladies

they are great fit well very warm

Love the bathers fit well and last

I love the soft feel of the thermal rashie. It was a perfect warmth between a standard rashie and a wetsuit

Love them

So comfortable, and a perfect warmth for a winter surf ski paddle

Love them

Love these tights. Perfect for jet ski, kayak, boating and winter swimming. Love love love!!

Love my thermal rashie, keeps be warm in winter beach training.

I teach swimming lessons and some of the mornings recently have been very cold. The mermaid thermal fitted Rashie is so comfortable and keeps me warm in the water. I love it.

Perfect fit.
Good material.

I bought the thermal tights and rashie to where paddling through winter. I was really looking forward to pulling them on this morning for our 5:30am paddle… and they did not disappoint. I’m stayed warm and comfortable all morning. I’ll be recommending them to other ladies in our club!
