“Ordered reaction and was to big in sleeves felt similar to my blue 70 synergie, a very nice wetsuit but older. So returned for smaller Helix. Felt stretch would help if a little small. So Helix went on very easy felt incredible and wow what a difference. Just incredible feel swam a 1.75 miles 59 degrees most comfortable wet suit ever. Only bad part is that says should only be used for races due to its build.. so train in old suit but can't wait to put back on Helix. Great wetsuit.”
