All armbands are suitable for use in water!
Always rinse your armband under running water after use in the sea or pool.
Measure the circumference of your arm where you usually place your sensor or pump (do not measure the device itself), and choose the correct size.

If your measurement falls between two sizes, we recommend selecting the larger one. However, the final choice depends on your personal preferences 

this is just our suggestion :)
If you're using it with an insulin pump (such as the Omnipod), add 2 cm to your arm circumference when selecting your size.
