Hi Catherine,
Thanks for your review, our Bahia range of wetsuits are manufactured using a durable UltraFlex DS Neoprene. If you are wanting a more flexible wetsuit, we would suggest looking at the O'Neill Hyper range of wetsuits, this includes the HyperFreak, HyperFire and HyperFire X. The Hyper range are made using the most flexible wetsuit materials available. For more information, check this link below;
