Koji Fine core warmer

The Koji Fine is a thin but snug, stretchy, waist-warming band. Pull this on after a cold swim and it will add an extra insulating layer to your core to help heat you through. Lots of warm layers are the best way to heat up slowly after chilly dips and this makes a great addition to the layering process.

It's so easy to step into, so cold, fumbling hands are not a problem and it can also double up as a modesty cover if you pull it over your boobs when changing.

Wear it next to your skin for a soft and warm base layer.

The Koji Fine is our thinnest Koji at 3mm thick and yet it still provides great warmth without being bulky. Choose this Koji if you want to forget you are wearing it or are trying to keep a sleeker look in your post-swim layering process. Also great for everyday wear in winter. 

Get cosy in a Koji! You'll end up wearing it all day - not just post swim!

Available in black and grey

Size Guide

The below is a guide but as the Koji Fine is a stretchy garment there is the possibility to size up or down. Size down for a snugger fit and size up for extra stretch (possibly to cover boobs when changing)

 Apologies for not having larger sizes in this Koji model
