We currently offer a choice of monthly or full season hires which are available on our Men's and Women's Advance wetsuits. 

The price of each hire consists of a hire charge, plus a deposit which we refund as soon as the hire suit is back with us. 

If you love your hire suit so much that you'd like to keep it once the hire period is up, just get in touch and we will work out the best solution for you. 


A range of articles and blogs to help you take it up a notch in your next event will be available here shortly!
