I have bought the two Br1 wetsuits both size medium and they fit amazing! I'm 5ft 8in waist 33in. by 30length. My son is 6ft 1in waist 30in. by 32length. It still is a perfect size for both of us. Daughter (4/3 rbz bones wetsuit) 10/12 in girls and the juniors 10 fits just a little baggy but I'm sure it will allow for 2 years of growth. The br1 is so silky smooth inside and out. No key pocket but still good. Extremely flexible like second skin. 4/3 Rbz juniors is still flexible and a little more stiff but that's expected. Ocean water on east coast was 60f and we didn't feel phased one bit. I would highly recommend buell wetsuits!!
