Find My Size

Our Hydra neoprene drysuit is available in stock sizes with a limited range of fitted boot sizes.
Use our calculator to find out which size is most suited to you.

Handy things to know before you start

The sizing allows for Xerotherm or Arctic under garments.

If you find yourself at the upper end of the size chart we suggest to go a size up especially if you would like to wear Arctic (thick) under garments with the suit.

Boot sizes allow for a Xerotherm or Arctic sock to be worn.

All bodies are different, therefore you may not find a perfect fitting suit using this chart. We suggest you find a local dealer with a stock suit you can try.
