Hi, I'm currently looking for a 2 piece open cell hooded wetsuit camo and 5mm. I've signed up to a freediving course but starting that next year. At the moment I'm not very fit also suffering with chronic spinal problems with sciatica. I've already started at the gym working on my core, and also swimming in the local river. At the moment I have a 3/2 mm gul wetsuit with my diving 5mm shorty over the top with a hood. The combo is OK, but I still get cold after a while, so looking for a proper suit and keep warmer for longer. Water here is about 10 deg c max atm. There are now so many to choose from so just asking for advice on a good suit. I've been looking at mares, cressi & a few other brands. I have a budget of £250. Thanks
